Call for Participation
Opinion Analysis Task at NTCIR Workshop 6
1. Introduction
¡@¡@Opinion Analysis is a pilot task in the series of NTCIR Workshops. In
recent years, several important conferences such as AAAI, ACL, COLING,
SIGIR, WWW, etc., have published works on opinion extraction, sentiment, and
subjective information analysis. However, no common platform for languages
other than English exists that can be used to evaluate these technologies.
In 2005, the open submission session at NTCIR-5 collected researchers¡¦
comments about a new pilot task. This pilot task aims to build
Chinese/English/Japanese opinion extraction corpora based on the past NTCIR
CLIR test collections, and to promote investigation of opinionated
information access.
¡@¡@Opinion extraction is one of the kernel technologies related to opinion
analysis tasks. In this pilot task, Chinese/English/Japanese sentences are
the basic units for extraction and relevance judgments. Opinions and the
opinion holders are the information we focus on. The test collection
consists of topics and the relevant documents. For each topic and the
corresponding relevant documents, participants have to report which
sentences have subjective information relevant to the designated topic,
their polarity, and the ¡§explicit¡¨ opinion holder. The detail
