Research Topics

Multimedia Understanding: Content, Context, and Sentiment
With the popularity of image-capturing devices and the success of Web 2.0 applications, people have seen a dramatic increase in their ability to collect digital information in various situations and share them on the Web. To develop a system that automatically recognizes the content of multimedia data, we study the complementary use of multi-modal features (e.g., visual features and textual features). We also investigate how to automatically understand images’ semantics, context, and sentiment

Knowledge Acquisition From Academic Databases
Discovering hot research topics or active research groups from academic databases can contribute to grasping scientific technology trends or to promoting collaborative researches. We, in cooperation with National Institute of Informatics, develop new techniques for analyzing CiNii Articles, the largest academic database in Japan. Specifically, we study the automatic construction of researcher networks based on research topics’ similarities. Visualizing such networks can provide us with new findings about the range of researchers’ interests or changes of research themes over time.
