| Outline of Final Research Achievements |
This research project aims to study an ecosystem for trend information that leads to new information creation through the sharing of the best practice of information access and utilization. Sub-goals of the project include: (1) technologies for supporting access and utilization of trend information, (2) framework for sharing the best practice, and (3) user experiments using the developed systems. As the main contributions of the project, (1) we developed an advanced version of the search engine designed for retrieving time series data, and monitoring support systems for text stream data. As for (2), we developed the framework for best-practice sharing, such as query recommendation function and the sharing of findings from trend information. Through the user experiments using the developed system, the effectiveness of sharing the best practice of information access/utilization is confirmed.
