The Use of Lexical Semantics in Information Extraction
Joyce Yue Chai, Alan W. Biermann · 1997
This paper presents a method for enabling users to specialize an information extraction system to satisfy their particular needs. The method allows the user to man- ually demonstrate the creation of seman- tic nodes and transitions while ecanning a sample text article using a graphical user interface. On the basis of such examples, the system creates rules that translate text to semantic nets; then it generalizes these rules so that they can apply to a broad class of text instead of only the training articles.
