Users can obtain information from large-scale web texts using keyword-based web search services. Such search services find information including keywords but not semantically matching information because natural language texts on the web are not machine-readable. In this paper, we develop a pattern mining method that extracts frequent semantic structures in the dependency trees of Japanese sentences. In order to deal with the flexible word order in Japanese, we propose feature expressions (SIT lists) consisting of the three sets of phase nodes in the dependency trees. In the evaluation experiment, we show that the pattern mining method for SIT lists enables us to flexibly extract common semantic patterns that are implicitly included in the dependency trees of Japanese sentences. |
