Research on sentiment analysis technology and polarity computation of sentiment words

With the rapid development of E-Commerce, customer reviews on a product grows rapidly. This makes it difficult for a potential customer to make an informed decision on purchasing the product, as well as for the manufacturer of the product to keep track and to manage customer opinions. All these works strongly depend on polarity analysis of sentiment words. This paper proposes a novel approach to realize polarity analysis of new words, in addition implement quantitative computation of sentiment words and automatic expansion of polarity lexicon. Experimental results show the feasibility and effectiveness of our approach.
