The Robert Gordon University at the Opinion Retrieval Task of the 2007 TREC Blog Track

Abstract. The Robert Gordon University (RGU) participated in the Opinion Retrieval Task of the Trec 2007 Blog Track. At the core of the system we developed is a set of training documents labeled with respect to opinion. These documents are used to train a classifier in order to classify the documents that are relevant to the given Trec topics. However, a major limitation with these training documents is that they are not always generic enough to serve as good training examples for all the 50 Trec topics. We therefore propose a solution that generalizes their content by exploiting the context of opinion related language constructs such as adjectives, verbs, and adverbs. Our system significantly improves over RGU’s previous Blog Track systems.
