What is Web Data Extraction ?

A user can easily copy and paste data from a web page. They can even download images and store the files names with the associated product text. For small amounts of data this is fine. But consider many rows of data across 10s, 100s or even 1000s of pages, this can be very time consuming and prone to human error.

Screen Scraping, Web Data Mining, Data Extraction are automated techniques of navigating and extracting data and images from a web site. Generally The Screen Scraping Software will work with a Web Crawler. The Web Crawler will be responsible for automatically navigating a web site.

The crawler will follow every link in a methodical way hunting for data to be scraped. When the crawler (sometimes know has Web Spiders or Web Bots) finds a page that the screen scraper is interested in (such as a product page) the crawler then calls upon the Screen Scraper to extract the information that is required

The extracted data that the screen scraper found is then cleansed, processed, transformed, translated as required and then stored in another place such as a spread sheet or database. Once the data is stored in Excel, CSV (Comma Separated Values) or a Database, it makes life much easier to use the data.
