| Research Abstract |
First, we automatically acquired linguistic knowledge from a large-scale web corpus. The acquired linguistic knowledge mainly consists of case frames, which describe the relations between predicates and their arguments. Then, we integrated such linguistic knowledge into a linguistic analyzer to improve the performance of the analyzer. We also developed an information retrieval system based on the knowledge-rich linguistic analyzer, and confirmed that our information retrieval system outperformed conventional information retrieval systems based on bag of words and dependency relations.
