Web Data Extraction is a process that able to digest target Web databases that are visible only as HTML pages, and create a local, identical replica of those databases as a result. What is needed in this process is much more than a Web crawler and set of Web site wrappers. A comprehensive data extraction process needs to deal with such roadblocks such as session identifiers, HTML forms, and client-side JavaScript, and data integration problems such as incompatible datasets and vocabularies, and missing and conflicting data.
