The paper presents methods of retrieving blog posts containing opinions about an entity expressed in the query. ...
Methods of structuring queries into facets, facet expansion using Wikipedia, and a facet-based retrieval are also investigated in this work. ...
While the general idea of faceted retrieval is not new, the paper proposes a novel method of facet identification in the query, expansion of each facet by means of Wikipedia, and use of facets in opinion ...

The faceted blog distillation task retrieves blogs (i.e. RSS feeds) that are not only relevant to a query but also satisfy an interested facet. ...
For the opinionated/factual facets, we propose a classifier that uses syntactic and semantic features to determine whether an opinion in blog documents is relevant to a given query. ...
Since opinion retrieval plays a central role in faceted blog distillation, we first evaluate our opinion-finding techniques using 100 TREC 2007-2008 queries over five TREC baselines (of documents) from ...
