Zhang, Kunpeng, Xie, Yusheng, Cheng, Yu, Honbo, Daniel, Downey, Doug, Agrawal, Ankit, Liao, Wei-keng and Choudhary, Alok (2012): Sentiment identification by incorporating syntax, semantics and context information. In: Proceedings of the 35th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 2012. pp. 1143-1144. http://dx.doi.org/10.1145/2348283.2348510

This paper proposes a method based on conditional random fields to incorporate sentence structure (syntax and semantics) and context information to identify sentiments of sentences within a document. It also proposes and evaluates two different active learning strategies for labeling sentiment data. The experiments with the proposed approach demonstrate a 5-15% improvement in accuracy on Amazon customer reviews compared to existing supervised learning and rule-based methods.
