| Research Abstract |
The essential purpose of Information Retrieval is not to get relevant documents, but to obtain relevant information and knowledge. In order to achieve this, we believe that text understanding by machine, or Natural Language Processing is the most important aspect. This research project constructed IR infrastructure based on structural NLP, analyzing predicate argument structures in texts, handling expressive diversity in natural language, and providing a bird's-eye view towards a given topic by organizing and relating information.
