Reasoning Through Search: A Novel Approach to Sentiment Classification

We introduce a novel approach to sentiment classication. Our Reasoning Through Search (RTS) technique uses existing labeled data, query formation strategies, and a case base to estimate the sentiment of a text review. Unlike previous systems, when classifying a document from a domain that the system does not have explicit, in-domain training data, our classication system leverages domain relatedness and a case base of labeled reviews to perform the classication. While the system does require labeled training data, it does not rely on the guaranteed presence of in-domain labeled training data.
