Opinion analysis from the social web contributions

Abstract

The paper focuses on the automatic opinion analysis related to web discussions. It introduces a method for solving basic problems of opinion analysis (determination of word subjectivity, polarity as well as intensity of this polarity). The method solves the reversion of polarity by negation as well as determination of polarity intensity of word combinations. A dynamic coefficient for the word combinations processing is introduced and an implementation of the method is presented. In addition, the paper describes test results of the presented implementation and discussion of these results as well. © 2011 Springer-Verlag Berlin Heidelberg.
