Site-Wide Wrapper Induction for Life Science Deep Web Databases
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
We present a novel approach to automatic information extraction from Deep Web Life Science databases using wrapper induction. ...
Our solution to this novel challenge of Site-Wide wrapper induction consists of a sequence of steps: 1. classification of similar Web pages into classes, 2. discovery of these classes and 3. wrapper induction ...
Site-Wide Wrapper Induction As we noted in section 1, data-intensive sites, such as those in the Life Sciences domain, have their data scattered across multiple pages. ...
