title = "A hybrid method of domain lexicon construction for opinion targets extraction using syntax and semantics",
abstract = "Considering opinion targets extraction of Chinese microblogs plays an important role in opinion mining, there has been a significant progress in this area recently, especially the CRF-based method. However, this method only takes lexical-related features into consideration and does not excavate the implied semantic and syntactic knowledge. We propose a new approach which incorporates domain lexicon with groups of features using syntax and semantics. The approach acquires domain lexicon through a novel way namely PDSP. And then we combine the domain lexicon with opinion targets extracted from CRF with groups of features together for opinion targets extraction. Experimental results on COAE2014 dataset show that this approach notably outperforms other baselines of opinion targets extraction.",
