Cut as a Querying Unit for WWW, Netnews, and E-mail

Abstract

In this paper, we propose a query framework for hypertext data, in particular, WWW pages, Netnews articles, and e-mails. In existing query tools for those hypertext data, such as search engines for WWW or intelligent news/mail readers, data units in query are individual nodes. In actual hypertext data, however, one topic is often described over a series of connected nodes, and therefore, the logical data unit should be such a series of nodes corresponding to one topic. This discrepancy between the data unit in query and the logical data unit hinders the efficient information discovery from hypertext data. To solve this problem, in our framework, we divide hypertexts into connected subgraphs corresponding individual topics, and we use those subgraphs as the data units in query.
