Abstract:

This paper describes a new automatic indexing method for Korean texts using the keyfact includes simple syntactic relations between adjacent words suitable for agglutinative languages, especially for Korean. We present the construction rules to compose keyfacts as indexing terms. The keyfact is defined a relevant pair controlled by predefined keyfact rules and is expressed in [head word, dependent word]. This method simplifies processing of compound noun, noun phrase, verb phrase and adjective phrase. By applying the keyfact concept, our system has raised the precision ratio of indexing terms.
