A generation model to unify topic relevance and lexicon-based sentiment for opinion retrieval

Min Zhang, Xingyao Ye
2008 Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '08  
With this model, the relevance-based ranking serves as the weighting factor of the lexicon-based sentiment ranking function, which is essentially different from the popular heuristic linear combination  ...  In this paper, we focus on lexicon-based opinion retrieval. A novel generation model that unifies topic-relevance and opinion generation by a quadratic combination is proposed in this paper.  ...  In section 3, we present our generation model for opinion retrieval that unifies topic relevance model and sentiment-based opinion generation.  ...
