Co-Extracting Opinion Targets and Opinion Words from Online Reviews Based On the Word Alignment Model
Abstract
The significant chore of estimation mining is to extract opinion targets and estimation vocabulary from a huge number of product reviews. The one of the come within reach of proposes a method base on partially supervised word arrangement representation, in which estimation relations naming is consider as an alignment process. Manipulative estimation relationship between words is an important for constructing Co-Ranking graph; to find self-assurance of each applicant graph based co-ranking algorithm is used. Higher confidence applicant are extracted as estimation targets or estimation words. Prior information also consider in finding confidence of applicant as being estimation target or estimation word. Previous methods are based on sentence structure based, compared to these methods proposed model minimizes negative effects of parsing errors. Due to use of partial supervision proposed model achieves better accuracy compared to unsupervised word alignment model. Final task is to extractive summary generation from estimation Targets and estimation Words with Word Alignment Model.
