Profile

子供の頃に電子工作に触れ、小学校の図書館でプログラミングの世界に出会いました。中学・高校時代は、BASICやアセンブリ言語、C言語でゲームを作るのが趣味でした。大学では、電気と情報の両方を専門とする学科に進み、コンピュータの可能性を広げたいと思い、人工知能を専門とする研究室を選びました。大学院生以降は自然言語処理に関する研究を進め、博士課程を修了しました。その後、特任研究員や准教授を経て、2017年に東京工業大学(現・東京科学大学)情報理工学院教授に着任しました。実社会で役に立つソフトウェアやサービスを意識しながら、人間のように言葉を理解し会話できるコンピュータの実現を目指し、研究と教育を展開しています。

    The research was carried out with an awareness of the trend in natural language processing research of the large language models. The research project advances language understanding, inference, and argumentation mining through studies on acquiring lexical knowledge from static word embeddings, adapting dynamic word embeddings to an existing ontology, language understanding from SNS text, aspect-based sentiment analysis based on generative language models, estimating confidence of natural language inference, predicting whether a language model is trained on a pre-training corpus with a targe knowledge, stance detection for each agenda item from meeting minutes, explaining the results of aspect-based sentiment analysis.

    This project aimed at the computational modeling of deep, robust discourse analysis that was able to "read between the lines" by integrating abductive reasoning, machine learning, and physical computing. The main achievements are as follows. First, we significantly enhanced the computational capacity of abductive reasoning by formalizing the problem as weighted maximum satisfiability and devising efficient pruning methods. Second, we developed novel methods for large-scale knowledge acquisition from both Web and Wikipedia documents and demonstrated the impact of leveraging acquired knowledge on semantic and discourse analysis. Third, we built and empirically evaluated a computational model that innovatively integrated abductive reasoning and physical simulation to predict risks involved in given traffic scenes. The resources and tools developed in this project are made publicly available on our website.

    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.

    This research builds Named Entity Recognizers, which extract text mentions of entities or concepts of specific semantic classes (e.g., product names and disease names) from text, at a low cost. In order to achieve this goal, this project addresses three challenges: (1) automatic acquisition of training data with mentions annotated with semantic classes; (2) building Named Entity Recognizers from the automatically acquired training data; and (3) evaluating the Named Entity Recognizers. We proposed a method for improving the quality of automatically acquired training data by using reference information in the dictionary, and demonstrated its effectiveness through the experiments. We also proposed a method for mining context gazetteers, which are dependency paths appearing around expressions of the target semantic classes, and confirmed improvements of accuracy of Named Entity Recognizers.
