Abstract:
In this paper, we describe linguistically sophisticated tools for the automatic annotation and navigation of on-line documents. Creation of these tools relies on research into finite-state technologies for the design and development of lexicallyintensive semantic indexing, shallow semantic understanding, and content abstraction techniques for texts. These tools utilize robust language processing techniques to generate multi-purpose data structures called LEXICAL WEBS, used in the system TEXTRACT, an automated semantic indexing program designed to parse, index, and hyperlink electronic documents.
