| Research Abstract |
In this research, we annotated opinion and opinion targets using Yahoo! Blog corpus and found that opinions were characterized with domains such as computer, entertainment, or politics. We also proposed opinion extraction system toward multiple domains based on ensemble learning. In NTCIR-8, we conduct multilingual opinion analysis task to evaluate opinion extraction technologies in Japanese, English, and Chinese. We also extended English appraisal dictionary toward Japanese dictionary and experimented opinion extraction in Japanese and English using two dictionaries. We also focused community question answering contents (CQA) to extract and summarize user opinions, and proposed good answer estimation and query expansion type Web retrieval systems. Finally, we proposed communication supporting systems mediating personal opinions such as : (1) facemark recommendation system based on emotion estimation using microblogs, (2) relation estimation system toward personal names and surrounding entities, and (3) example-based machine translation system using alignment clues in parallel multilingual corpus.
