Title: Limits of Opinion-Finding Baseline Systems
Published: July 21, 2008
Abstract: In opinion-finding, the retrieval system is tasked with re- trieving not just relevant documents, but which also express an opinion towards the query target entity. Most opinion- finding systems are based on a two-stage approach, where initially the system aims to retrieve relevant documents, which are then re-ranked according to the extent to which they are detected to be of an opinionated nature. In this work, we investigate how the underlying baseline retrieval system performance affects the overall opinion-finding per- formance. We apply two effective opinion-finding techniques to all the baseline runs submitted to the TREC 2007 Blog track, and draw new insights and conclusions.
