Web scraping (web harvesting or web data extraction) is a computer software technique of extracting information from websites. Usually, such software programs simulate human exploration of the World Wide Web by either implementing low-level Hypertext Transfer Protocol (HTTP), or embedding a fully-fledged web browser, such as Internet Explorer or Mozilla Firefox.

Web scraping is closely related to web indexing, which indexes information on the web using a bot or web crawler and is a universal technique adopted by most search engines. In contrast, web scraping focuses more on the transformation of unstructured data on the web, typically in HTML format, into structured data that can be stored and analyzed in a central local database or spreadsheet. Web scraping is also related to web automation, which simulates human browsing using computer software. Uses of web scraping include online price comparison, contact scraping, weather data monitoring, website change detection, research, web mashup and web data integration.


Web scraping is the process of automatically collecting information from the World Wide Web. It is a field with active developments sharing a common goal with the semantic web vision, an ambitious initiative that still requires breakthroughs in text processing, semantic understanding, artificial intelligence and human-computer interactions. Current web scraping solutions range from the ad-hoc, requiring human effort, to fully automated systems that are able to convert entire web sites into structured information, with limitations.

Human copy-and-paste: Sometimes even the best web-scraping technology cannot replace a human’s manual examination and copy-and-paste, and sometimes this may be the only workable solution when the websites for scraping explicitly set up barriers to prevent machine automation.

Text grepping and regular expression matching: A simple yet powerful approach to extract information from web pages can be based on the UNIX grep command or regular expression-matching facilities of programming languages (for instance Perl or Python).

HTTP programming: Static and dynamic web pages can be retrieved by posting HTTP requests to the remote web server using socket programming.

HTML parsers: Many websites have large collections of pages generated dynamically from an underlying structured source like a database. Data of the same category are typically encoded into similar pages by a common script or template. In data mining, a program that detects such templates in a particular information source, extracts its content and translates it into a relational form, is called a wrapper. Wrapper generation algorithms assume that input pages of a wrapper induction system conform to a common template and that they can be easily identified in terms of a URL common scheme. Moreover, some semi-structured data query languages, such as XQuery and the HTQL, can be used to parse HTML pages and to retrieve and transform page content.

DOM parsing: By embedding a full-fledged web browser, such as the Internet Explorer or the Mozilla browser control, programs can retrieve the dynamic content generated by client-side scripts. These browser controls also parse web pages into a DOM tree, based on which programs can retrieve parts of the pages.

Web-scraping software: There are many software tools available that can be used to customize web-scraping solutions. This software may attempt to automatically recognize the data structure of a page or provide a recording interface that removes the necessity to manually write web-scraping code, or some scripting functions that can be used to extract and transform content, and database interfaces that can store the scraped data in local databases.

Vertical aggregation platforms: There are several companies that have developed vertical specific harvesting platforms. These platforms create and monitor a multitude of “bots” for specific verticals with no "man in the loop" (no direct human involvement), and no work related to a specific target site. The preparation involves establishing the knowledge base for the entire vertical and then the platform creates the bots automatically. The platform's robustness is measured by the quality of the information it retrieves (usually number of fields) and its scalability (how quick it can scale up to hundreds or thousands of sites). This scalability is mostly used to target the Long Tail of sites that common aggregators find complicated or too labor-intensive to harvest content from.

Semantic annotation recognizing: The pages being scraped may embrace metadata or semantic markups and annotations, which can be used to locate specific data snippets. If the annotations are embedded in the pages, as Microformat does, this technique can be viewed as a special case of DOM parsing. In another case, the annotations, organized into a semantic layer, are stored and managed separately from the web pages, so the scrapers can retrieve data schema and instructions from this layer before scraping the pages.

Computer vision web-page analyzers: There are efforts using machine learning and computer vision that attempt to identify and extract information from web pages by interpreting pages visually as a human being might

Three Common Methods For Web Data Extraction

Three Common Methods For Web Data Extraction

Probably the most common technique used traditionally to extract data from web pages this is to cook up some regular expressions that match the pieces you want (e.g., URL's and link titles). Our screen-scraper software actually started out as an application written in Perl for this very reason. In addition to regular expressions, you might also use some code written in something like Java or Active Server Pages to parse out larger chunks of text. Using raw regular expressions to pull out the data can be a little intimidating to the uninitiated, and can get a bit messy when a script contains a lot of them. At the same time, if you're already familiar with regular expressions, and your scraping project is relatively small, they can be a great solution.

Other techniques for getting the data out can get very sophisticated as algorithms that make use of artificial intelligence and such are applied to the page. Some programs will actually analyze the semantic content of an HTML page, then intelligently pull out the pieces that are of interest. Still other approaches deal with developing "ontologies", or hierarchical vocabularies intended to represent the content domain.

There are a number of companies (including our own) that offer commercial applications specifically intended to do screen-scraping. The applications vary quite a bit, but for medium to large-sized projects they're often a good solution. Each one will have its own learning curve, so you should plan on taking time to learn the ins and outs of a new application. Especially if you plan on doing a fair amount of screen-scraping it's probably a good idea to at least shop around for a screen-scraping application, as it will likely save you time and money in the long run.

So what's the best approach to data extraction? It really depends on what your needs are, and what resources you have at your disposal. Here are some of the pros and cons of the various approaches, as well as suggestions on when you might use each one:

Raw regular expressions and code


- If you're already familiar with regular expressions and at least one programming language, this can be a quick solution.
- Regular expressions allow for a fair amount of "fuzziness" in the matching such that minor changes to the content won't break them.
- You likely don't need to learn any new languages or tools (again, assuming you're already familiar with regular expressions and a programming language).
- Regular expressions are supported in almost all modern programming languages. Heck, even VBScript has a regular expression engine. It's also nice because the various regular expression implementations don't vary too significantly in their syntax.

Ontologies and artificial intelligence


- You create it once and it can more or less extract the data from any page within the content domain you're targeting.
- The data model is generally built in. For example, if you're extracting data about cars from web sites the extraction engine already knows what the make, model, and price are, so it can easily map them to existing data structures (e.g., insert the data into the correct locations in your database).
- There is relatively little long-term maintenance required. As web sites change you likely will need to do very little to your extraction engine in order to account for the changes.

Screen-scraping software


- Abstracts most of the complicated stuff away. You can do some pretty sophisticated things in most screen-scraping applications without knowing anything about regular expressions, HTTP, or cookies.
- Dramatically reduces the amount of time required to set up a site to be scraped. Once you learn a particular screen-scraping application the amount of time it requires to scrape sites vs. other methods is significantly lowered.
- Support from a commercial company. If you run into trouble while using a commercial screen-scraping application, chances are there are support forums and help lines where you can get assistance.

Scrape Data from Website is a Proven Way to Boost Business Profits

Data scraping is not a new technology in market. Several business persons use this method to get benefited from it and to make good fortune. It is the procedure of gathering worthwhile data that has been located in the public domain of the internet and keeping it in records or databases for future usage in innumerable applications.

There is a large amount of data available only through websites. However, as many people have found out, trying to copy data into a usable database or spreadsheet directly out of a website can be a tiring process. Manual copying and pasting of data from web pages is shear wastage of time and effort. To make this task easier there are a number of companies that offer commercial applications specifically intended to scrape data from website. They are proficient of navigating the web, evaluating the contents of a site, and then dragging data points and placing them into an organized, operational databank or worksheet.

Web scraping company

Every day, there are numerous websites that are hosting in internet. It is almost impossible to see all the websites in a single day. With this scraping tool, companies are able to view all the web pages in internet. If a business is using an extensive collection of applications, these scraping tools prove to be very useful.

It is most often done either to interface to a legacy system which has no other mechanism which is compatible with current hardware, or to interface to a third-party system which does not provide a more convenient API. In the second case, the operator of the third-party system will often see screen scraping as unwanted, due to reasons such as increased system load, the loss of advertisement revenue, or the loss of control of the information content.

Scrape data from website greatly helps in determining the modern market trends, customer behavior and the future trends and gathers relevant data that is immensely desirable for the business or personal use.

To Know Difference Of Data Mining And Web Screen Scraping

To Know Difference Of Data Mining And Web Screen Scraping

Screen scraping to find information, where data mining can analyze information possible. This is a great simplification, so I will work a bit.

World Fast Forward, screen scraping websites than ever refers to extract information. Computer programs "crawl" or "spider" through web sites, pulls the data. For many people the comparison shopping engine, archive web pages, or a spreadsheet for a text so that it can be filtered to analyze things like build to download.

Data mining, on the other hand, is defined by Wikipedia as "the practice of automatically search large stores of data for patterns. Other words, you already know, and you know about the useful things about care. Thus we have the right pages of text data mining, automated data collection, web data extraction, and the bloody website is preferred.

If your two-card Treasure popular poker forums and read to your poker "data mining" many of the technical discussion of the saw, and thought how it can help you win more money. In this article I will give you an introduction to poker data mining and clarify some common misconceptions.

Poker data mining is a process where you (I) is a poker hand histories ("Data") collected in the game without taking part yourself. After the collected hand, you Holder Manager, your opponents to play in a program like Advanced Statistics can import. Normally determine the player playing style.

In addition, many people enjoy watching the high stakes games and save your favorite poker professionals with the hand history. For a special "hand grabber" data mine the program. A hand grabber a small program that runs in the background and the “clock” poker table for your computer, and protects them from the hand history, if any are found.

For an expensive mobile phone, screen protector because of your unfailing security forces has the best security. Transparent cover can hardly be seen because it is very thin. But this does not mean that it is not difficult if the scratches and resists any form.

In fact, invisible shield, even if you close your eyes, hold the phone, you can hardly see. Degree of protection as their heavy armor, although seem thin and irrelevant. Invisible Shield is just a shell for the phone, the phone is not interrupted. If you have a cable that you connect to the touch screen as before to use.

It is possible for you to buy full body armor kit, which is a security for the phone. Screen coverage is absolutely necessary, and the slope of the touch screen can also be purchased. But for the kit to buy the entire cover of the phone because it marks or scratches from all sides to protect the whole phone is recommended.

Data Extraction Product vs Web Scraping Service which is best?

Product v/s Service: Which one is the real deal?

With analytics and especially market analytics gaining importance through the years, premier institutions in India have started offering market analytics as a certified course. Quite obviously, the global business market has a huge appetite for information analytics and big data.

While there may be a plethora of agents offering data extraction and management services, the industry is struggling to go beyond superficial and generic data-dump creation services. Enterprises today need more intelligent and insightful information.

The main concern with product-based models would be their incapability to extract and generate flexible and customizable data in terms of format. This shortcoming can be majorly attributed to the almost-mechanical process of the product- it works only within the limits and scope of the algorithm.

To place things into perspective, imagine you run an apparel enterprise. You receive two kinds of data files. One contains data about everything related to fashion- fashion magazines, famous fashion models, make-up brand searches, apparel brands trending and so on. On the other hand, the data is well segregated into trending apparel searches, apparel competitor strategies, fashion statements and so on. Which one would you prefer? Obviously, the second one- this is more relevant to you and will actually make life easier while drawing insights and taking strategic calls.

In the scenario where an enterprise wishes to cut down on overhead expenses and resources to clean the data and process it into meaningful information, that’s when the heads turn towards service-based web extraction. The service-based model of web extraction has customization and ready-to-consume data as its key distinction feature.

Web extraction, in process parlance is a service that dives deep into the world of internet and fishes out the most relevant data and activities. Imagine a junkyard being thoroughly excavated and carefully scraped to find you the exact nuts, bolts and spares you need to build the best mechanical project. This is metaphorically what web extraction offers as a service.

The entire excavation process is objective and algorithmically driven. The process is carried out with a final motive of extracting meaningful data and processing it into insightful information. Though the algorithmic process leads to a major drawback of duplication, unlike a web extractor (product), wweb extraction as a service entails a de-duplication process to ensure that you are not loaded with redundant and junk data.

Of the most crucial factors, successive crawling is often ignored. Successive crawling refers to crawling certain web pages repetitively to fetch data. What makes this such a big deal? Unwelcomed successive crawling can lead to attracting the wrath of the site owners and the high probability of being sued for a class action suit.

While this is a very crucial concern with web scraping products , web extraction as a service takes care of all the internet ethics and code of conduct while respecting the politeness policies of web pages and permissible penetration depth limits.

Botscraper ensures that if a process is to be done, it might as well be done in a very legal and ethical manner. Botscraper uses world class technology to ensure that all web extraction processes are conducted with maximum efficacy while playing by the rules.

An important feature of the service model of web extraction is its capability to deal with complex site structures and focused extraction from multiple platforms. Web scraping as a service requires adhering to various fine-tuning processes. This is exactly what botscraper offers along with a highly competitive price structure and a high class of data quality.

While many product-based models tend to overlook the legal aspects of web extraction, data extraction from the web as a service covers it much more ingeniously. While associating with botscraper as web scraping service provider, legal problems should be the least of your worries.

Botscraper as a company and technology ensures that all politeness protocol, penetration limits, robots.txt and even the informal code of ethics is considered while extracting the most relevant data with high efficiency.  Plagiarism and copyright concerns are dealt with utmost care and diligence at Botscraper.

The key takeaway would be that, product-based web extraction models may look appealing from a cost perspective- that too only at the face of it, but web extraction as a service is what will fetch maximum value to your analytical needs. Ranging right from flexibility, customization to legal coverage, web extraction services score above web extraction product and among the web extraction service provider fraternity, botscraper is definitely the preferred choice.

Web Data Extraction

Web Data Extraction

The Internet as we know today is a repository of information that can be accessed across geographical societies. In just over two decades, the Web has moved from a university curiosity to a fundamental research, marketing and communications vehicle that impinges upon the everyday life of most people in all over the world. It is accessed by over 16% of the population of the world spanning over 233 countries.

As the amount of information on the Web grows, that information becomes ever harder to keep track of and use. Compounding the matter is this information is spread over billions of Web pages, each with its own independent structure and format. So how do you find the information you're looking for in a useful format - and do it quickly and easily without breaking the bank?

Search Isn't Enough

Search engines are a big help, but they can do only part of the work, and they are hard-pressed to keep up with daily changes. For all the power of Google and its kin, all that search engines can do is locate information and point to it. They go only two or three levels deep into a Web site to find information and then return URLs. Search Engines cannot retrieve information from deep-web, information that is available only after filling in some sort of registration form and logging, and store it in a desirable format. In order to save the information in a desirable format or a particular application, after using the search engine to locate data, you still have to do the following tasks to capture the information you need:

· Scan the content until you find the information.

· Mark the information (usually by highlighting with a mouse).

· Switch to another application (such as a spreadsheet, database or word processor).

· Paste the information into that application.

Its not all copy and paste

Consider the scenario of a company is looking to build up an email marketing list of over 100,000 thousand names and email addresses from a public group. It will take up over 28 man-hours if the person manages to copy and paste the Name and Email in 1 second, translating to over $500 in wages only, not to mention the other costs associated with it. Time involved in copying a record is directly proportion to the number of fields of data that has to copy/pasted.

Is there any Alternative to copy-paste?

A better solution, especially for companies that are aiming to exploit a broad swath of data about markets or competitors available on the Internet, lies with usage of custom Web harvesting software and tools.

Web harvesting software automatically extracts information from the Web and picks up where search engines leave off, doing the work the search engine can't. Extraction tools automate the reading, the copying and pasting necessary to collect information for further use. The software mimics the human interaction with the website and gathers data in a manner as if the website is being browsed. Web Harvesting software only navigate the website to locate, filter and copy the required data at much higher speeds that is humanly possible. Advanced software even able to browse the website and gather data silently without leaving the footprints of access.
