Wiccap Data Model: Mapping Physical Websites to Logical Views
[chapter]
2002
Lecture Notes in Computer Science
Preserved Fulltext
To do this, information from the Web sources need to be extracted automatically according to users' interests. ...
We propose the Wiccap Data Model, an XML data model that maps Web information sources into commonly perceived logical models. ...
One of the solutions to this information overloading problem is Information Extraction (IE) from the Web. ...
