Our laboratory’s research is focused on text-based content and media studies. The major challenges include :
- Acquisition and utilization of semantic language models Information identification and entity disambiguation; automatic construction of linguistic resources
- Computer understanding of natural languages Exploiting the semantic structure of natural language; Extracting knowledge and information from natural language
- Modeling human language activities Measuring and analyzing language activities in text media
Our recent research topics are as follows: retrieval and understanding of mathematical expressions, analyzing the behavior of readers by using gaze tracking methods, semantic and social structures of online communication, analysis of the deep semantic structures of the Japanese language, real-scale information identification, and recommender systems for academic research. We also welcome new research topic proposals related to natural language processing and information retrieval. Our research facilities include variety of information resources and a large-scale computation platform at NII. Students are encouraged to act as independent researchers by being allowed to join seminars and discussion groups with interdisciplinary and international researchers and to participate in related joint research activities at NII.
