DCU at the TREC 2008 Blog Track

Abstract

In this paper we describe our system, experiments and results from our participation in the Blog Track at TREC 2008. Dublin City University participated in the adhoc retrieval, opinion finding and polarised opinion finding tasks. For opinion finding, we used a fusion of approaches based on lexicon features, surface features and syntactic features. Our experiments evaluated the relative usefulness of each of the feature sets and achieved a significant improvement on the baseline.
