| Outline of Final Research Achievements |
Attribute to the recent development on the information processing and communication technology, people started to offer information in spoken language and in written language exchangeably and interactively, which then have been recorded electronically. This study aims to develop a technology to handle both speech and text without distinction and to make use of each advantage complementarily in information access. We developed the method of making use of spontaneously spoken query to express one's information need, the method of using spontaneously spoken query and text keyword query at the same time, the method of document retrieval targeting heterogeneous document collection of speech and text related mutually, and the method of dealing with heterogeneous training data to train a classifier targeting microblogs.

| Academic Significance and Societal Importance of the Research Achievements |
言葉は、それを伝える媒体の違いから、話し言葉(音声言語)と書き言葉(文字言語)に分類され、それぞれ別の機能を担ってきた。しかし、情報の電子的な記録の促進や情報通信技術の発展により、音声言語と文字言語の機能分担が不明瞭になり相互交換的に利用され記録されるようになった。本研究の成果により、このような不均質な情報の利用が促進されるとともに、音声言語と文字言語のそれぞれの利点を活かす技術の開発が進むと考えられる。
