| Outline of Final Research Achievements |
This research aimed to study a unified framework for a formal representation of natural language semantics. Natural language semantics involves logical relations, semantic relations among words and phrases, tense and aspect, and discourse relations, while they have complicated interactions with each other. However, linguistic studies mainly focused on a specific issue in each research field, and no framework for representing these features in a unified way. Therefore, we developed a unified formal representation of natural language semantics based on the analysis of textual entailment corpora. In addition, we developed a system for textual entailment recognition, and demonstrated that our framework allows for fast and high accuracy semantic inference.
