Abstract
</SectionTitle>
    <Paragraph position="0"> This paper describes an approach to identifying the syntactic role of an antecedent in a Korean relative clause, which is essential to structural disambiguation and semantic analysis. In a learning phase, linguistic knowledge such as conceptual co-occurrence patterns and syntactic role distribution of antecedents is extracted from a large-scale corpus. Then, in an application phase, the extracted knowledge is applied in determining the correct syntactic role of an antecedent in relative clauses. Unlike previous research based on co-occurrence patterns at the lexical level, we represent co-occurrence patterns with concept types in a thesaurus. In an experiment, the proposed method showed a high accuracy rate of 90.4% in resolving ambiguitie s of syntactic role determination of antecedents. null</Paragraph>
