| Outline of Final Research Achievements |
We investigated design of user interface for efficient browsing of message streams (e.g., emails and timelines of social media), and proposed an interface that classify messages based on some of their properties and shows the messages in multiple tabs, instead of simply listing all messages in one stream in reverse-chronological order or in importance order. In order to implement such an interface, we also developed methods of automatically classifying messages (particularly tweets in Twitter) into those tabs. Our methods infer the purpose of the user sending the messages and the purpose of the user receiving the messages, and then classify the messages based on these results.
