Data scraping tool for non-coding journalists launches

A tool which helps non-coding journalists scrape data from websites has launched in public beta today.

Import.io lets you extract data from any website into a spreadsheet simply by mousing over a few rows of information.

Until now import.io, which we reported on back in April, has been available in private developer preview and has been Windows only. It is now also available for Mac and is open to all.

Although import.io plans to charge for some services at a later date, there will always be a free option.

The London-based start-up is trying to solve the problem of the fact that there is "lots of data on the web, but it's difficult to get at", Andrew Fogg, founder of import.io, said in a webinar last week.

Those with the know-how can write a scraper or use an API to get at data, Fogg said. "But imagine if you could turn any website into a spreadsheet or API."

Uses for journalists

Journalists can find stories in data. For example, if I wanted to do a story on the type of journalism jobs being advertised and the salaries offered, I could research this by looking at various websites which advertise journalism jobs.

If I were to gather the data from four different jobs boards and enter the information manually into a spreadsheet it would take would take hours if not days; if I were to write a screen scraper for each of the sites it would require knowledge and would probably take a couple of hours. Using import.io I can create a single dataset from multiple sources in a few minutes.

I can then search and sort the dataset and find out different facts, such as how many unpaid internships are advertised, or how many editors are currently being sought.

How it works

When you download the import.io application you see a web browser. This browser allows you to enter a URL for any site you want to scrape data from.

To take the example of the jobs board, this is structured data, with the job role, description and salaries displayed.

The first step is to set up 'connectors' and to do this you need to teach the system where the data is on the page. This is done by hitting a 'record' button on the right of the browser window and mousing over a few examples, in this case advertised jobs. You then click 'train rows'.

It takes between two and five examples to teach import.io where all of the rows are, Fogg explained in the webinar.

The next step is to declare the type of data and add column names. For example there may be columns for 'job title', 'job description' and 'salary'. Data is then extracted into the table below the browser window.

Data from different websites can then be "mixed" into a single searchable database.

In the example used in the webinar, Fogg demonstrated how import.io could take data relating to rucksacks for sale on a shopping website. The tool can learn the "extraction pattern", Fogg explained, and apply that to to another product. So rather than mousing over the different rows of sleeping bags advertised, for example, import.io was automatically able to detect where the price and product details were on the page as it had learnt the structure from how the rucksacks were organised. The really smart bit is that the data from all products can then be automatically scraped and pulled into the spreadsheet. You can then search 'shoes' and find the data has already been pulled into your database.

When a site changes its code a screen scraper would become ineffective. Import.io has a "resilience to change", Fogg said. It runs tests twice a day and users get notified of any changes and can retrain a connector.

It is worth noting that a site that has been scraped will be able to detect that import.io has extracted the data as it will appear in the source site's web logs.

Case studies

A few organisations have already used import.io for data extraction. Fogg outlined three.

    British Red Cross

The British Red Cross wanted to create an iPhone app with data from the NHS Choices website. The NHS wanted the charity to use the data but the health site does not have an API.

By using import.io, data was scraped from the NHS site. The app is now in the iTunes store and users can use it to enter a postcode to find hospital information based on the data from the NHS site.

"It allowed them to build an API for a website where there wasn't one," Fogg said.

    Hewlett Packard

Fogg explained that Hewlett Packard wanted to monitor the prices of its laptops on retailers' websites.

They used import.io to scrape the data from the various sites and were able monitor the prices at which the laptops were being sold in real-time.

    Recruitment site

A US recruitment firm wanted to set up a system so that when any job vacancy appeared on a competitor's website, they could extract the details and push that into their Salesforce software. The initial solution was to write scrapers, Fogg said, but this was costly and in the end they gave up. Instead they used import.io to scrape the sites and collate the data.

ScraperWiki lets anyone scrape Twitter data without coding

The Obama administration’s open data mandate announced on Thursday was made all the better by the unveiling of the new ScraperWiki service on Friday. If you’re not familiar with ScraperWiki, it’s a web-scraping service that has been around for a while but has primarily focused on users with some coding chops or data journalists willing to pay to have someone scrape data sets for them. Its new service, though, currently in beta, also makes it possible for anyone to scrape Twitter to create a custom data set without having to write a single line of code.

Taken alone, ScraperWiki isn’t that big of a deal, but it’s part of a huge revolution that has been called the democratization of data. More data is becoming available all the time — whether from the government, corportations or even our own lives — only it’s not of much use unless you’re able to do something with it. ScraperWiki is now one of a growing list of tools dedicated to helping everyone, not just expert data analysts or coders, analyze — and, in its case, generate — the data that matters to them.

After noticing a particularly large numbers of tweets in my stream about flight delays yesterday, I thought I’d test out ScraperWiki’s new Twitter search function by gathering a bunch of tweets directed to @United. The results — from 1,697 tweets dating back to May 3 — are pretty fun to play with, if not that surprising. (Also, I have no idea how far back the tweet search will go or how long it will take using the free account, which is limited to 30 minutes of compute time a day. I just stopped at some point so I could start digging in.)

First things first, I ran my query. Here’s what the data looks like viewed in a table in the ScraperWiki app.

Next, it’s a matter of analyzing it. ScraperWiki lets you view it in a table (like above), export it to Excel or query it using SQL, and will also summarize it for you. This being Twitter data, the natural thing to do seemed to be analyzing it for sentiment. One simple way to do this right inside the ScraperWiki table is to search for a particular term that might suggest joy or anger. I chose a certain four-letter word that begins with f.

Surprisingly, I only found eight instances. Here’s my favorite: “Your Customer Service is better than a hooker. I paid a bunch of money and you’re still…” (You probably get the idea.)

But if you read my “data for dummies” post from January, you know that we mere mortals have tools at our disposal for dealing with text data in a more refined way. IBM’s Many Eyes service won’t let me score tweets for sentiment, but I can get a pretty good idea overall by looking at how words are used. For this job, though, a simple word cloud won’t work, even after filtering out common words, @united and other obvious terms. Think of how “thanks” can be used sarcastically and you can see why.

Using the customized word tree, you can see that “thanks” sometimes means “thanks.” Other times, not so much. I know it’s easy to dwell on the negative, but consider this: “worst” had 28 hits while “best” had 15. One of those was referring to Tito’s vodka and at least three were referring to skyline views. (Click here to access it and search by whatever word you want.)

Here’s a phrase net filtering the results by phrases where the word “for” connects two words.

Anyhow, this was just a fast, simple and fairly crude example of what ScraperWiki now allows users to do, and how that resulting data can be combined with other tools to analyze and visualize it. Obviously, it’s more powerful if you can code, but new tools are supposedly on the way (remember, this is just a beta version) that should make it easier to scrape data from even more sources.

In the long term, though, services like ScraperWiki should become a lot more valuable as tools for helping us generate and analyze data rather than just believe what we’re told. Want to improve your small business, put your life in context or perhaps just write the best book report your teacher has ever seen? It’s getting easier every day.

What is data scraping and how can I stop it?

Data scraping (also called web scraping) is the process of extracting information from websites. Data scraping focuses on transforming unstructured website content (usually HTML) into structured data which can be stored in a database or spreadsheet.

The way data is scraped from a website is similar to that used by search bots – human web browsing is simulated by using programs (bots) which extract (scrape) the data from a website.

Unfortunately, there is no efficient way to fully protect your website from data scraping. This is so because data scraping programs (also called data scrapers or web scrapers) obtain the same information as your regular web visitors.

Even if you block the IP address of a data scraper, this will not prevent it from accessing your website. Most data scraping bots use large IP address pools and automatically switch the IP address in case one IP gets blocked. And if you block too many IPs, you will most probably block many of your legitimate visitors.

One of the best ways to protect globally accessible data on a website is through copyright protection. This way you can legally protect the intellectual ownership of your website content.

Another way to protect your site content is to password protect it. This way your website data will be available only to people who can authenticate with the correct username and password.

Easy Answer To The Question, What Is Screen Scraping

What is screen scraping? First of all it isnâEUR(TM)t data mining. People take it for an advance from of data mining but in reality it is just opposite. It is a program that extracts

more than simple data. It drags images and even large files from websites and this is what makes it different from simple data mining.

This program is used for different purposes like contact and address list extraction. Contact details of Internet users are beneficial for websites that approach customers for

business. Instead of waiting for visitors to come and provide their contact details, website owners could get the contacts of a large number of Internet users. The process is

simple and it takes shortest possible time to present the data in a desired format.

It is a program hence it is made. There are groups that have mastered the art of making software that could draw load of data from different websites. You need data; you could

contact such a group and get a program made for you. It wonâEUR(TM)t cost you a fortune nor would you need waiting for long to get the program made. The moment you would

forward your request; the programmers would start working on it.

What is screen scraping? This question could be better answered by the tasks it does. It is used for data extraction like extracting products from suppliers, pricing that

competitor sites are using, monitoring social media and archiving online data to help make right choice. Simple data mining canâEUR(TM)t do this job and if you try, you would

find that it is a time consuming and laborious job.

Greatest advantage of this program is that it produces required data within a short time. There is no data loss and also you get latest data. Is it possible with manual data

mining? No and for this reason data mining couldnâEUR(TM)t be the answer of what is screen scraping? Online businesses run on data. They generate tons of data every day.

This data could be scraped using a program and not mined manually.

What is screen scraping? It is a process of simplifying data extraction and also making a website more user-friendly. Filling web forms sometimes becomes a tedious affair and

that is why a few visitors fill online forms. With perfect programming, a website could make its forms user-friendly and help visitors fill the data by clicking at the boxes.

Understanding Web Scraping

It is evident that the invention of the internet is one of the greatest inventions of life. This is so because it allows quick recovery of information from large databases. Though the internet has its own negative aspects, its advantages outweigh the demerits f using it. It is therefore the objective of every researcher to understand the concept of web scraping and learn the basics of collecting accurate data from the internet. The following are some of the skills researchers need to know and keep them abreast of:

Understanding File Extensions in Web Scraping

In web scraping the first step to know is file extensions. For instance a site ending with dot-com is either a sales or commercial site. With the involvement of sales activity in such a website, there is a possibility that the data contained therein is inaccurate. Sites that may be ending with dot-gov are sites owned by various governments. The information found on such websites is accurate since they are reviewed by professionals regularly. Sites ending with dot-org are sites owned by non-governmental organizations that are not after making profit. There is a greater probability that the information contained is not accurate. Sites ending with dot-edu are owned by educational institutions. The information found on such sites is sourced by professionals and is of high quality. In case you have no understanding concerning a particular website it is important that get more information from expert data mining services.

Search Engine Limitations in Web Scraping

After understanding the file extensions, the next step is to understand search engine limitations applied to web scraping. These include process such as file extension, filtering or any other parameters. The following are some of the restrictions that need to typed after your search term: for instance if you key in “finance” and then click “search” all sites will be listed from the dot-com directory that contain the word finance on its website. If you key in “finance site.gov,” of course with the quotation marks, only the government sites that have the word finance will be listed. The same applies to other sites with different file extensions.

Advanced Parameters in Web Scraping

When performing web scraping it is important to understand more skills beyond the file extension. Therefore there is a need to understand particular search terms. For instance if you key in “software company in India” without the quotation marks, the search engines will display thousands of websites having “software”, “company” and India in their search terms. If you key in “Software Company in India” with the quotation marks, the search engines will only display sites that contain the exact phrase “software company in India” within their text.

This article forms the basis of web scraping. Collection of data needs to be carried out by experts and high quality tools. This is to ensure that the quality and accuracy of the data scraped is of high standards. The information extracted from that data has wide applications in business operations including decision making and predictive analytics.

A Solution to Mobile Phone Data Issues

One subject of mobile phone ownership that cocmes up time after time is data usage. Data usage can be a controversial area for both the consumer and the mobile network but with a little help there is a solution. The networks continually don’t help themselves, they have a poor track record when monitoring and reporting data usage back to the end user. We see many times that the billing provided can be misleading or altogether inept for the purpose of monitoring the spend. With some networks the information is hidden within a very complex report or the usage is only recorded when the data bundle is exceeded. Once exceeded the cost becomes disproportionate to going over the bundled minutes so regularly we have seen bills of £300 and above for a one month overage on data.

This can be where the problems really begin as you are now in the situation of knowing there is something wrong, the bill doesn’t help so you call the network. At this point you will more than likely get the stock answer as to why the problem has occurred which is ‘we don’t know’. They don’t know because when data is consumed the network record the information as usage by volume of consumption and not what the data has been used for. So imagine how you would feel if you had a £300 overage in a month and the networks were unable to shed any light on it, this happens all the time.

What we need to do is understand how much data we need then ensure we put measures in to assess the usage. Smartphone’s consume data as a natural process continually updating the apps and operating systems. In fact they consume so much data that even if you don’t pick the phone up and leave it switched on it will consume on average 200MB per month. This is the point where the networks and re-sellers start to cause issues as they can often sell Smartphone packages with data bundles less than 200MB. Obviously the consumer then gets hit with a costly and unnecessary bill all within the first month of owning their new mobile phone. To prevent this you have to choose a bundle somewhere around the 500MB mark to allow for generic browsing and updates. You can still exceed this if choosing to download continually so there has to be an element of management by the user.

The first point to make is that a Smartphone will use data direct from the mobile network which eats into you data bundle and also over Wi-Fi. Wi-Fi usage does not cost the Smartphone airtime account so if you set the Smartphone to automatically select known Wi-Fi points when in range you will dramatically change the bundled data usage. It should become a habit that Wi-Fi is used to download anything out of the ordinary leaving plenty of the network bundle left for generic updates.

To help further there is an App called 3G watchdog that will help to manage the volumes used. Download this app from the App markets and install on the handset. There are many bespoke setting for the software so take your time to understand how it all works. What the correct setting will give is a measure at any point in the month of how many MB’s used either by Wi-Fi or 3g. Having the information then lets you adjust your usage or split in usage accordingly making you more aware of reaching the limit. The app will project forward your present use and tell you how many MBS will be used by the time your month end arrives.

It also has a shutdown system just in case you experience a virus or background app consuming data without your knowledge. Once again all you need to do is adjust the setting and tell the software to either alert you or shut down the data when a user defined percentage of data is achieved. This is a very key part to not exceeding the data bundle as in most overage cases a data heavy application is running in the background of the phone without the user’s knowledge. This simple feature on 3G watchdog will ensure that even if that happens the data will deactivate automatically and there is no affect on the billing.

2. What is the usage pattern, in terms of purpose and the categories for the need for financial analysis?

3. Is the development of a tool for financial analysis through web scraping techniques possible?

Web scraping can be regarded as the procedure of extracting or harvesting knowledge for the large quantities of data. It is also known as Knowledge Discovery in Database (KDD). This implies that web scraping involves data collection, data management, database creation and the analysis of data and its understanding.

The following are some of the steps that are involved in web scraping service:

1. Data cleaning. This is the process of removing nose and the inconsistent data. This process is important as it only ensures that only important data should be integrated. This process saves time that will be consumed in the next processes.

2. Data integration. This is the processes of combining multiple sources of information. This process is quite important as it ensure that there is sufficient data for selection purposes.

3. Data selection. This is retrieving of data from databases that are relevant from the data in question.

4. Data transformation. It is the process of consolidating or transforming data into forms, which are appropriate for scraping by performing aggregation operations and summary.
5. Data mining. This is the process where intelligent methods are used in extracting data patterns.

6. Pattern evaluation. It is the identification of the patterns that are quite interesting and ones that represent knowledge and the interesting measures.

7. Knowledge presentation. It is the process where knowledge representation techniques and visualization are used in representing extracted data to the user.

Data Warehouse

Data warehouse may be defined as a store where information that has been mined from different sources, and stored under a unified schema and it resides at a single site.

Majority of banks and financial institutions offer a wide variety of baking services that include checking account balances, savings, customer and business transactions. Other services that may be offered by such companies include investment and credit services. Stock and insurance services may also be offered.

Through web scraping services it is possible for companies to gather data from financial and banking sectors, which may be relatively reliable, high quality and complete. Such data is quite important is it facilitates the analysis and the decision making of a company.

Web Scraping

Web scraping, also known as Web data extraction or Web harvesting, is a software method of extracting data from websites. Web scraping is closely related and similar to Web indexing, which indexes Web content. Web indexing is the method used by most search engines. The difference with Web scraping is that it focuses more on the translation of unstructured content on the Web, characteristically in rich text format like that of HTML, into controlled data that can be analyzed stored and in a spreadsheet or database. Web scraping also makes Web browsing more efficient and productive for users. For example, Web scraping automates weather data monitoring, online price comparison, and website change recognition and data integration.

This clever method that uses specially coded software programs is also used by public agencies. Government operations and Law enforcement authorities use data scrape methods to develop information files useful against crime and evaluation of criminal behaviors. Medical industry researchers get the benefit and use of Web scraping to gather up data and analyze statistics concerning diseases such as AIDS and the most recent strain of influenza like the recent swine flu H1N1 epidemic.

Data scraping is an automatic task performed by a software program that extracts data output from another program, one that is more individual friendly. Data scraping is a helpful device for programmers who have to generate a line through a legacy system when it is no longer reachable with up to date hardware. The data generated with the use of data scraping takes information from something that was planned for use by an end user.

One of the top providers of Web scraping software, Mozenda, is a Software as a Service company that provides many kinds of users the ability to affordably and simply extract and administer web data. Using Mozenda, individuals will be able to set up agents that regularly extract data then store this data and finally publish the data to numerous locations. Once data is in the Mozenda system, individuals may format and repurpose data and use it in other applications or just use it as intelligence. All data in the Mozenda system is safe and sound and is hosted in a class A data warehouses and may be accessed by users over the internet safely through the Mozenda Web Console.

One other comparative software is called the Djuggler. The Djuggler is used for creating web scrapers and harvesting competitive intelligence and marketing data sought out on the web. With Dijuggles, scripts from a Web scraper may be stored in a format ready for quick use. The adaptable actions supported by the Djuggler software allows for data extraction from all kinds of webpages including dynamic AJAX, pages tucked behind a login, complicated unstructured HTML pages, and much more. This software can also export the information to a variety of formats including Excel and other database programs.

Web scraping software is a ground-breaking device that makes gathering a large amount of information fairly trouble free. The program has many implications for any person or companies who have the need to search for comparable information from a variety of places on the web and place the data into a usable context. This method of finding widespread data in a short amount of time is relatively easy and very cost effective. Web scraping software is used every day for business applications, in the medical industry, for meteorology purposes, law enforcement, and government agencies.

Ultimate Scraping Three Common Methods For Web Data Extraction

So what's the best way to data extraction? It really is dependent upon what your needs are, and what resources you have you can use. Here are some of the pros and cons of the various options, as well as suggestions on once you might use each an individual:

Raw regular expressions in addition to code

<em>Advantages: </em>

- If you're already informed about regular expressions and some form of programming language, this may be a quick solution.

- Regular expressions allow for a fair amount of "fuzziness" inside the matching such that minor changes towards the content won't break them all.

- You likely don't should try to learn any new languages or perhaps tools (again, assuming you're already informed about regular expressions and a new programming language).

- Regular expressions are supported in most of modern programming languages. Daylights, even VBScript has a daily expression engine. It's also nice for the reason that various regular expression implementations don't vary too significantly within their syntax.

<em>Disadvantages: </em>

- They are definitely complex for those that don't have plenty of experience with them. Figuring out regular expressions isn't want going from Perl for you to Java. It's more enjoy going from Perl to make sure you XSLT, where you really have to wrap your mind around an entirely different way of viewing the condition.

- They're often confusing to evaluate. Take a look through a number of the regular expressions people have manufactured to match something as simple as an email address and you'll see what i mean.

- If the content you're endeavoring to match changes (e. h., they change the internet page by adding a brand-new "font" tag) you'll likely must update your regular expressions to take into account the change.

- The data discovery component to the process (traversing various web pages to go to the page containing the data you want) will still should be handled, and can get fairly complex region deal with cookies and additionally such.

<em>When to make use approach: </em> You'll most in all likelihood use straight regular expressions in screen-scraping when you experience a small job you intend to get done quickly. Especially if you now know regular expressions, there's no sense in stepping into other tools if all you decide to do is pull some news headlines off a site.

Ontologies as well as artificial intelligence

<em>Advantages: </em>

- You create the software once and it can awfully extract the data from any page while in the content domain you're looking for.

- The data model is mostly built in. For case in point, if you're extracting data files about cars from online sites the extraction engine now knows what the help to make, model, and price are generally, so it can easily map it to existing data structures (e. gary the gadget guy., insert the data throughout the correct locations in ones own database).

- There is certainly relatively little long-term preservation required. As web sites change you likely might want to do very little to all your extraction engine as a way to account for the transformations.

<em>Disadvantages: </em>

- It's relatively complex for making and work with this engine. The level of expertise needed to even understand an removal engine that uses man-made intelligence and ontologies is noticeably higher than what must deal with regular words and phrases.

Challenges in Effective Web Data Mining

Data collection and web data mining are critical processes for many companies and the marketing companies today. The techniques usually used include search engines,

topic-based searches and directories. Web data mining is necessary for any business that wants to create data warehouses by harvesting data from the internet. This is so

because high-quality and intelligent information may not be harvested from the internet easily. Such information is critical as it enables you to get desired results and the

business intelligence in demand.
Keyword-based searches are important in marketing of company products. They are usually affected by the following factors:
• Irrelevant pages. The use of common and general keywords on the search engines yields millions of web pages. Some of thesepages may be irrelevant and may not be of help

to the user.
• Ambiguous results.This is usually caused by multi-variant or similar keyword semantics. A name would be an animal, movie or even a sport accessory. This results in web

pages that are different what you are actually searching for.
• Possibility of missing some web pages.There is a great possibility of missing the most relevant information that is contained on web pages that are not indexed on a given

keyword.
One of the factors that prohibit the usage of web data mining is the effectiveness of search engine crawlers. This is widely evidenced by lack of access of the entire web due to

search engine crawlers and bot.This can be attributed partly tobandwidth limitations. It is important to understand that there are thousands of databases on the internet that can

deliver well-maintained information, high quality and are not easily accessed by crawlers.
In web data mining it is important to understand that majority of search engines have limited choices or alternatives for keyword query combination. For instance, yahoo and

Google offer option like phrase and even the exact matches that may limit even the search results. It is usually demands more efforts and even time and thereby get the most

important and relevant information.The human behavior and the alternatives usually change of time.This therefore implies that web pages need to be updated frequently and

there by reflect on the emerging trends. It is important to realize that there is a limited space for web data mining. This is so because the information that currently exists is

heavily relied on keyword-based indices. This does not apply for the real data.
It is important to realize that web data mining is an important tool for any business. It is therefore important to embrace this technology to solve data crisis problems. There are

several limitations and many challenges which may have resulted in the quest of effectively and efficiently in rediscovering the use of web resources. However, irrespective of the

challenges of web data mining, this technology is an effective tool that can be employed in many technological and scientific fields. It is therefore paramount to embrace this

technology and use it fully in order to realize your corporate goals.

Web Scraper Shortcode WordPress Plugin Review

This short post is on the WP-plugin called Web Scraper Shortcode, that enables one to retrieve a portion of a web page or a whole page and insert it directly into a post. This plugin might be used for getting fresh data or images from web pages for your WordPress driven page without even visiting it. More scraping plugins and sowtware you can find in here.

To install it in WordPress go to Plugins -> Add New.
Usage

The plugin scrapes the page content and applies parameters to this scraped page if specified. To use the plugin just insert the

[web-scraper ]

shortcode into the HTML view of the WordPress page where you want to display the excerpts of a page or the whole page. The parameters are as follows:

    url (self explanatory)
    element – the dom navigation element notation, similar to XPath.
    limit – the maximum number of elements to be scraped and inserted if the element notation points to several of them (like elements of the same class).

The use of the plugin is of the dom (Data Object Model) notation, where consecutive dom nodes are stated like node1.node2; for example: element = ‘div.img’. The specific element scrape goes thru ‘#notation’. Example: if you want to scrape several ‘div’ elements of the class ‘red’ (<div class=’red’>…<div>), you need to specify the element attribute this way: element = ‘div#red’.
How to find DOM notation?

But for inexperienced users, how is it possible to find the dom notation of the desired element(s) from the web page? Web Developer Tools are a handy means for this. I would refer you to this paragraph on how to invoke Web Developer Tools in the browser (Google Chrome) and select a single page element to inspect it. As you select it with the ‘loupe’ tool, on the bottom line you’ll see the blue box with the element’s dom notation:


The plugin content

As one who works with web scraping, I was curious about  the means that the plugin uses for scraping. As I looked at the plugin code, it turned out that the plugin acquires a web page through ‘simple_html_dom‘ class:

    require_once(‘simple_html_dom.php’);
    $html = file_get_html($url);
    then the code performs iterations over the designated elements with the set limit

Pitfalls

    Be careful if you put two or more [web-scraper] shortcodes on your website, since downloading other pages will drastically slow the page load speed. Even if you want only a small element, the PHP engine first loads the whole page and then iterates over its elements.
    You need to remember that many pictures on the web are indicated by shortened URLs. So when such an image gets extracted it might be visible to you in this way: , since the URL is shortened and the plugin does not take note of  its base URL.
    The error “Fatal error: Call to a member function find() on a non-object …” will occur if you put this shortcode in a text-overloaded post.

Summary

I’d recommend using this plugin for short posts to be added with other posts’ elements. The use of this plugin is limited though.

Visual Web Ripper: Using External Input Data Sources

Sometimes it is necessary to use external data sources to provide parameters for the scraping process. For example, you have a database with a bunch of ASINs and you need to scrape all product information for each one of them. As far as Visual Web Ripper is concerned, an input data source can be used to provide a list of input values to a data extraction project. A data extraction project will be run once for each row of input values.

An input data source is normally used in one of these scenarios:

    To provide a list of input values for a web form
    To provide a list of start URLs
    To provide input values for Fixed Value elements
    To provide input values for scripts

Visual Web Ripper supports the following input data sources:

    SQL Server Database
    MySQL Database
    OleDB Database
    CSV File
    Script (A script can be used to provide data from almost any data source)

To see it in action you can download a sample project that uses an input CSV file with Amazon ASIN codes to generate Amazon start URLs and extract some product data. Place both the project file and the input CSV file in the default Visual Web Ripper project folder (My Documents\Visual Web Ripper\Projects).

For further information please look at the manual topic, explaining how to use an input data source to generate start URLs.

Scraping Amazon.com with Screen Scraper

Let’s look how to use Screen Scraper for scraping Amazon products having a list of asins in external database.

Screen Scraper is designed to be interoperable with all sorts of databases and web-languages. There is even a data-manager that allows one to make a connection to a database (MySQL, Amazon RDS, MS SQL, MariaDB, PostgreSQL, etc), and then the scripting in screen-scraper is agnostic to the type of database.

Let’s go through a sample scrape project you can see it at work. I don’t know how well you know Screen Scraper, but I assume you have it installed, and a MySQL database you can use. You need to:

    Make sure screen-scraper is not running as workbench or server
    Put the Amazon (Scraping Session).sss file in the “screen-scraper enterprise edition/import” directory.
    Put the mysql-connector-java-5.1.22-bin.jar file in the “screen-scraper enterprise edition/lib/ext” directory.
    Create a MySQL database for the scrape to use, and import the amazon.sql file.
    Put the amazon.db.config file in the “screen-scraper enterprise edition/input” directory and edit it to contain proper settings to connect to your database.
    Start the screen scraper workbench

Since this is a very simple scrape, you just want to run it in the workbench (most of the time you want to run scrapes in server mode). Start the workbench, and you will see the Amazon scrape in there, and you can just click the “play” button.

Note that a breakpoint comes up for each item. It would be easy to save the scraped details to a database table or file if you want. Also see in the database the “id_status” changes as each item is scraped.

When the scrape is run, it looks in the database for products marked “not scraped”, so when you want to re-run the scrapes, you need to:

UPDATE asin
SET `id_status` = 0

Have a nice scraping! ))

Using External Input Data in Off-the-shelf Web Scrapers

There is a question I’ve wanted to shed some light upon for a long time already: “What if I need to scrape several URL’s based on data in some external database?“.

For example, recently one of our visitors asked a very good question (thanks, Ed):

    “I have a large list of amazon.com asin. I would like to scrape 10 or so fields for each asin. Is there any web scraping software available that can read each asin from a database and form the destination url to be scraped like http://www.amazon.com/gp/product/{asin} and scrape the data?”

This question impelled me to investigate this matter. I contacted several web scraper developers, and they kindly provided me with detailed answers that allowed me to bring the following summary to your attention:
Visual Web Ripper

An input data source can be used to provide a list of input values to a data extraction project. A data extraction project will be run once for each row of input values. You can find the additional information here.
Web Content Extractor

You can use the -at”filename” command line option to add new URLs from TXT or CSV file:

    WCExtractor.exe projectfile -at”filename” -s

projectfile: the file name of the project (*.wcepr) to open.
filename – the file name of the CSV or TXT file that contains URLs separated by newlines.
-s – starts the extraction process

You can find some options and examples here.
Mozenda

Since Mozenda is cloud-based, the external data needs to be loaded up into the user’s Mozenda account. That data can then be easily used as part of the data extracting process. You can construct URLs, search for strings that match your inputs, or carry through several data fields from an input collection and add data to it as part of your output. The easiest way to get input data from an external source is to use the API to populate data into a Mozenda collection (in the user’s account). You can also input data in the Mozenda web console by importing a .csv file or importing one through our agent building tool.

Once the data is loaded into the cloud, you simply initiate building a Mozenda web agent and refer to that Data list. By using the Load page action and the variable from the inputs, you can construct a URL like http://www.amazon.com/gp/product/%asin%.
Helium Scraper

Here is a video showing how to do this with Helium Scraper:


The video shows how to use the input data as URLs and as search terms. There are many other ways you could use this data, way too many to fit in a video. Also, if you know SQL, you could run a query to get the data directly from an external MS Access database like
SELECT * FROM [MyTable] IN "C:\MyDatabase.mdb"

Note that the database needs to be a “.mdb” file.
WebSundew Data Extractor
Basically this allows using input data from external data sources. This may be CSV, Excel file or a Database (MySQL, MSSQL, etc). Here you can see how to do this in the case of an external file, but you can do it with a database in a similar way (you just need to write an SQL script that returns the necessary data).
In addition to passing URLs from the external sources you can pass other input parameters as well (input fields, for example).
Screen Scraper

Screen Scraper is really designed to be interoperable with all sorts of databases. We have composed a separate article where you can find a tutorial and a sample project about scraping Amazon products based on a list of their ASINs.

A simple way to turn a website into JSON

Recently, while surfing the web I stumbled upon an simple web scraping service named Web Scrape Master. It is a kind of RESTful web service that extracts data from a specified web site and returns it to you in JSON format.
How it works

Though I don’t know what this service may be useful for, I still like its simplicity: all you need to do is to make an HTTP GET request, passing all necessary parameters in the query string:
http://webscrapemaster.com/api/?url={url}&xpath={xpath}&attr={attr}&callback={callback}

    url  - the URL of the website you want to scrape
    xpath – xpath determining the data you need to extract
    attr - attribute the name you need to get the value of (optional)
    callback - JSON callback function (optional)

For example, for the following request to our testing ground:

http://webscrapemaster.com/api/?url=http://testing-ground.extract-web-data.com/blocks&xpath=//div[@id=case1]/div[1]/span[1]/div

You will get the following response:

[{"text":"<div class='name'>Dell Latitude D610-1.73 Laptop Wireless Computer</div>","attrs":{"class":"name"}}]
Visual Web Scraper

Also, this service offers a special visual tool for building such requests. All you need to do is to enter the URL of the website and click to the element you need to scrape:
Visual Web Scraper
Conclusion

Though I understand that the developer of this service is attempting to create a simple web scraping service, it is still hard to imagine where it can be useful. The task that the service does can be easily accomplished by means of any language.

Probably if you already have software receiving JSON from the web, and you want to feed it with data from some website, then you may find this service useful. The other possible application is to hide your IP when you do web scraping. If you have other ideas, it would be great if you shared them with us.

Online Data Entry and Data Mining Services

Data entry job involves transcribing a particular type of data into some other form. It can be either online or offline. The input data may include printed documents like Application forms, survey forms, registration forms, handwritten documents etc.

Data entry process is an inevitable part of the job to any organization. One way or other each organization demands data entry. Data entry skills vary depends upon the nature of the job requirement, in some cases data to be entered from a hard copy formats and in some other cases data to be entered directly into a web portal. Online data entry job generally requires the data to be entered in to any online data base.

For a super market, data associate might be required to enter the goods which have sold in a particular day and the new goods received in a particular day to maintain the stock well in order. Also, by doing this the concerned authorities will get an idea about the sale particulars of each commodity as they requires. In another example, an office the account executive might be required to input the day to day expenses in to the online accounting database in order to keep the account well in order.

The aim of the data mining process is to collect the information from reliable online sources as per the requirement of the customer and convert it to a structured format for the further use. The major source of data mining is any of the internet search engine like Google, Yahoo, Bing, AOL, MSN etc. Many search engines such as Google and Bing provide customized results based on the user's activity history. Based on our keyword search, the search engine lists the details of the websites from where we can gather the details as per our requirement.

Collect the data from the online sources such as Company Name, Contact Person, Profile of the Company, Contact Phone Number of Email ID Etc. are doing for the marketing activities. Once the data is gathered from the online sources into a structured format, the marketing authorities will start their marketing promotions by calling or emailing the concerned persons, which may result to create a new customer. So basically data mining is playing a vital role in today's business expansions. By outsourcing the data entry and its related works, you can save the cost that would be incurred in setting up the necessary infrastructure and employee cost.

E-dataentry is an offshore India based company providing superior quality data mining services to clients across the globe with high level of accuracy at reasonable price.

Unraveling the Data Mining Mystery - The Key to Dramatically Higher Profits

Data mining is the art of extracting nuggets of gold from a set of seemingly meaningless and random data. For the web, this data can be in the form of your server hit log, a database of visitors to your website or customers that have actually purchased from your web site at one time or another.

Today, we will look at how examining customer purchases can give you big clues to revising/improving your product selection, offering style and packaging of products for much greater profits from both your existing customers and an increased visitor to customer ratio.

To get a feel for this, lets take a look at John, a seller of vitamins and nutritional products on the internet. He has been online for two years and has made a fairly good living at selling vitamins and such online but knows he can do better but isn't sure how.

John was smart enough to keep all customer sales data in a database which was a good idea because it is now available for analysis. The first step is for John to run several reports from his database.

In this instance, these reports include: repeat customers, repeat customer frequency, most popular items, least popular items, item groups, item popularity by season, item popularity by geographic region and repeat orders for the same products. Lets take a brief look at each report and how it could guide John to greater profits.

    Repeat Customers - If I know who my repeat customers are, I can make special offers to them via email or offer them incentive coupons (if automated) surprise discounts at the checkout stand for being such a good customer.
    Repeat Customer Frequency - By knowing how often your customer buys from you, you can start tailoring automatic ship programs for that customer where every so many weeks, you will automatically ship the products the customer needs without the hassle of reordering. It shows the customer that you really value his time and appreciate his business.
    Repeat Orders - By knowing what a customer repeatedly buys and by knowing about your other products, you can make suggestions for additional complimentaty products for the customer to add to the order. You could even throw in free samples for the customer to try. And of course, you should try to get the customer on an auto-ship program.
    Most Popular Items - By knowing what items are purchased the most, you will know what items to highlight in your web site and what items would best be used as a loss-leader in a sale or packaged with other less popular items. If a popular product costs $20 and it is bundled with another $20 product and sold for $35, people will buy the bundle for the savings provided they perceive a need of some sort for the other product.
    Least Popular Items - This fact is useful for inventory control and for bundling (described above.) It is also useful for possible special sales to liquidate unpopular merchandise.
    Item Groups - Understanding item groups is very important in a retail environment. By understanding how customer's typically buy groups of products, you can redesign your display and packaging of items for sale to take advantage of this trend. For instance, if lots of people buy both Vitamin A and Vitamin C, it might make sense to bundle the two together at a small discount to move more product or at least put a hint on their respective web pages that they go great together.
    Item Popularity by season - Some items sell better in certain seasons than others. For instance, Vitamin C may sell better in winter than summer. By knowing the seasonability of the products, you will gain insight into what should be featured on your website and when.
    Item Popularity by Geographic Region - If you can find regional buying patterns in your customer base, you have a great opportunity for personalized, targeted mailings of specific products and product groups to each geographic region. Any time you can be more specific in your offering, your close percentage increases.

As you can see, each of these elements gives very valuable information that can help shape the future of this business and how it conducts itself on the web. It will dictate what new tools are needed, how data should be presented, whether or not a personal experience is justified (i.e. one that remembers you and presents itself based on your past interactions), how and when special sales should be run, what are good loss leaders, etc.

Although it can be quite a bit of work, data mining is a truly powerful way to dramatically increase your profit without incurring the cost of capturing new customers. The cost of being more responsive to an existing customer, making that customer feel welcome and selling that customer more product more often is far less costly than the cost of constantly getting new customers in a haphazard fashion.

Even applying the basic principles shared in this article, you will see a dramatic increase in your profits this coming year. And if you don't have good records, perhaps this is the time to start a system to track all this information. After all, you really don't want to be throwing all that extra money away, do you?

Data Mining - A Short Introduction

Data mining is an integral part of data analysis which contains a series of activities that goes from the 'meaning' of the ideas, to the 'analysis' of the data and up to the 'interpretation' and 'evaluation' of the outcome. The different stages of the technique are as follows:

Objectives for Analysis: It is sometimes very difficult to statistically define the phenomenon we wish to analyze. In fact, the business objectives are often clear, but the same can be difficult to formalize. A clear understanding of the crisis and the goals is very important setup the analysis correctly. This is undoubtedly, one of the most complex parts of the process, since it establishes the techniques to be engaged and as such, the objectives must be crystal clear and there should not be any doubt or ambiguity.

Collection, grouping and pre-processing of the data: Once the objectives of the analysis are set and defined, we need to gather or choose the data needed for the study. At first, it is essential to recognize the data sources. Usually data are collected from the internal sources as the same are economical and more dependable and moreover these data also has the benefit of being the outcome of the experiences and procedures of the business itself.

Investigative analysis of the data and their conversion: This stage includes a preliminary examination of the information available. It involves a preliminary assessment of the significance of the gathered data. An exploratory and / or investigative analysis can highlight the irregular data. An exploratory analysis is important because it lets the analyst choose the most suitable statistical method for the subsequent stage of the analysis.

Choosing statistical methods: There are multiple statistical methods that can be put into use for the purpose of analysis, so it is very essential to categorize the existing methods. The choice statistical method is case specific and depends on the problem and also upon the type of information available.

Data analysis on the basis of chosen methods: Once the statistical method is chosen, the same must be translated into proper algorithms for working out the results. Ranges of specialized and non-specialized software are widely available for data mining and as such it is not always required to develop ad hoc computation algorithms for the most 'standard' purpose. However, it is essential that the people managing the data mining method well aware and have a good knowledge and understanding of the various methods of data analysis and also the different software solutions available for the same, so that they may adapt the same in times of need of the company and can flawlessly interpret the results.

Assessment and contrast of the techniques used and selection of the final model for analysis: It is of utmost necessity to choose the best 'model' from the variety of statistical methods accessible. The selection of the model should be based in contrast with the results obtained. When assessing the performance of a specific statistical method and / or type, all other dependent and / or relevant criterions should also be considered. The other criterions may be the constraints on the company both in terms of time and resources or it may be in terms of quality and the accessibility of data.

Elucidation of the selected statistical model and its employment in the decision making process: The scope of data mining is not limited to data analysis rather it is also includes the integration of the results so as to facilitate the decision making process of the company. Business awareness, the pulling out of rules and their use in the decision process allows us to proceed from the diagnostic phase to the phase of decision making. Once the model is finalized and tested with an information set, the categorization rule can be generalized. But the inclusion of the data mining process in the business should not be done in haste; rather the same should always be done slowly, setting out sensible and logical aims. The final aim of data mining is to be an integral supporting part of the company's decision making process.
