Outline of Final Research Achievements

In this project, we have constructed a corpus for extracting useful information related to the experiment of nanocrystal device development (e.g., Source material and parameters) and developed an automatic information extraction system NaDev that tries to extract such information from papers. By using NaDev, we can extract characteristic keywords related to the experiment (e.g., source material, experimental parameter) and these extracted keywords are used for calculating similarity among different papers and information retrieval system that have query construction support. In this project, we proposed a figure retrieval system that uses such parameter information as query.
