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. Introduction In this paper, we describe the construction of lexical webs. Lexical webs are normalized structured representations of the core semantic content of a text. The creation of lexical webs accelerates the availability of information in a highly indexed and cross-referenced format, facilitating navigation and rapid information access. One result of this research is the development of T...
