What is web extration?
Web extration is the collection of relevant data from web sites that is then stored in a data base to be used by a variety of people. This type of information can be used to build a data base of medical conditions, research topics, and more. The information is gathered and sorted by a software program that used "bots" to crawl web pages. This information can then be sorted and put into proper categories for us. Many professional agencies use these types of programs for their data base. An example could be the Web MD site, its a collection of medical conditions, their symptoms and what type of treatment is recommended. Similar programs are used by Police departments, fire departments and others.
