Research Abstract

This research aims to acquire linguistic knowledge from a large text, and utilize it for improving the accuracy of linguistic analysis. The linguistic knowledge acquired from a large Web text and Wikipedia includes the similarity between words, knowledge between events, and a large-scale lexical knowledge such as synonym and hypernym, and it is managed in integrated and consistent manner. Furthermore, the acquired linguistic knowledge was utilized for improving the accuracy of linguistic analysis such as textual entailment recognition and named entity recognition.
