ThesWB: A Tool for Thesaurus Construction from HTML Documents

Electronically available documents on the Web are exploding at an ever-increasing rate. Many Web documents, however, contain rich knowledge that describes the document's content. The Web can be viewed as a body of text containing two fundamentally different types of data: the contents and the tags. A tag is in HTML (Hyper-Text Markup Language) meta-data describing the layout and linking structure between the text. For these kinds of documents we can apply different approaches to extract and structure terms automatically. These approaches are based on a statistical model and syntactic analysis that describe the data of interest, including relationships, and context keywords. In this paper, we discuss an approach to extracting and structuring terms from documents posted on the Web to construct a thesaurus. The proposed tool, ThesWB is used to construct domain independent thesaurus from HTML pages. ThesWB is used to capture the internal structure of meta information embedded in HTML documents.
