چکیده
This paper describes an overview of the Opinion Analysis Pilot Task from 2006 to 2007 at the Sixth NTCIR Workshop. We created test collection for 32, 30, and 28 topics (11,907, 15,279, and 8,379 sentences) in Chinese, Japanese and English. Using this test collection, we conducted opinion extraction subtask. The subtask was defined from four perspectives: (a) opinionated sentence judgment, (b) opinion holder extraction, (c) relevance sentence judgment, and (d) polarity judgment. 21 run results were submitted by 14 participants with five results submitted by the organizers. We show the evaluation results of the groups participating in opinion extraction subtask.
