Text categorization using lexical chains

In this report I present a prototype system for use in dynamic text categorization research. The system implements lexical chaining, as described in recent literature. On top of this is built a simple extension to use for automatically identifying one or several categories to place a given text in. The initial tests presented in this report does not give any useful results, however, it give rise to new questions and possible directions for future research of lexical chaining and its uses in text categorization. Along with the implementation, previous research and the lexicographic database WordNet are discussed.
