York University at TREC 2008: Blog Track
York University participated in the TREC 2008 Blog track, by introducing two opinion finding features. By initially focusing solely on the sentiment terms found in a document, using two different methods, and not considering the topic relevance, we saw an overall negative impact in the final evaluations. Post-TREC improvements show the necessity of combining opinion weights with the topic relevance scores. A tunable combination function is used, which revealed some interesting findings about the opinion finding features noting the strengths and weaknesses. We also introduce the Compass Information Retrieval system, which is based on Okapi, as the driver by which these experiments were conducted.
