RIKEN Center for Advanced Intelligence Project Knowledge Acquisition Team

Team Leader: Yuji Matsumoto (D.Eng.)

Research Summary

Yuji  Matsumoto(D.Eng.)

A huge amount of knowledge is being produced along with the advance of scientific fields. Such expert knowledge is partly organized in domain databases, but a large portion of it is still kept in scholarly documents. It is time-consuming and cumbersome to construct domain databases and to conduct content-aware retrieval of scholarly documents. The Knowledge Acquisition Team aims at text/figure analysis and knowledge extraction from scholarly documents and also at development of infrastructure for content-aware retrieval of scholarly documents through domain database completion, knowledge organization, relation and summarization technologies.
