Extracting the comparative relations for mobile reviews

This paper devotes the research on the comparative reviews in the field of mobiles. For the comparative reviews, the study builds a comparative feature lexicon and a superlative feature lexicon, and then classifies the words in the comparative feature lexicon according to their polarities. During the extracting, an identifying method based on the naming characteristics is proposed for the comparative entities. For the comparative results, the study constructs 6 extracting patterns to apply to the comparative reviews. Finally, a formula is given to calculate the comparative result. The experimental results demonstrate the feasibility of this method.
