This paper describes an approach to identify- ing the syntactic role of an antecedent in a Ko- rean relative clause, which is essential to struc- tural disambiguation and semantic analysis. In a learning phase, linguistic knowledge such as conceptual co-occurrence patterns and syntac- tic role distribution of antecedents is extracted from a large-scale corpus. Then, in an appli- cation phase, the extracted knowledge is ap- plied in determining the correct syntactic role of an antecedent in relative clauses. Unlike pre- vious 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 am- biguities of syntactic rol...
