Semantic Indexing and Typed Hyperlinking

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..

LiveInfo: Adapting Web Experience by Customization and Annotation

. Intermediaries are perfectly suited to customizing and annotating web pages, as they can stand in the flow of data between web browser and web server, monitoring user behavior and modifying page markup. In this paper, we present LiveInfo, an intermediary-based framework for customizing and annotating web pages. LiveInfo breaks customization /annotation into four steps: (a) splitting streaming data into useful chunks, (b) identifying meaningful patterns of chunks, (c) merging together overlapping patterns, and (d) adding markup to customize and annotate. Each of these steps is easily replaced or configured, making it simple to adapt web experience by customization and annotation. 1 Introduction The World Wide Web (WWW) presents users with a particular view of information --- the view that the information authors built into it. Systems for adapting the web to individual users or to groups of users can present di#erent views of the available information. Many approaches for a..
