| Outline of Final Research Achievements |
In order to realize computers that can understand and infer on natural languages, a mechanism for collecting and utilizing the commonsense knowledge is essential. We need address three research topics, acquisition of a large-scale knowledge base, grounding a text with the knowledge base, and an inference method on the grounded text. In this project, we built corpora where a text is grounded on instances of a knowledge base. In order to associate relational patterns into a knowledge base, we proposed a novel method for composing a vector of a relation pattern from its constituent words and for disambiguating the sense of a relation pattern. We demonstrated the effectiveness of these studies not only by the experiments on individual tasks but also by applying downstream tasks such as question answering and stance detection.
