by Gilad Mishne, University of Amsterdam
Published in Trec 2006

From the abstract:

We describe our participation in the Opinion Retrieval task at TREC 2006. Our approach to identifying opinions in blog post consisted of scoring the posts separately on various aspects associated with an expression of opinion about a topic, including shallow sentiment analysis, spam detection,and link-based authority estimation. The separate approaches were combined into a single ranking, yielding significant improvement over a content-only baseline.

UPDATE: New, Poster Highlighting Results includes “3 Blog Retrieval Myths”
