Optimization Of Cross Domain Sentiment Analysis Using Sentiwordnet
This work addresses sentiment analysis for review classification, but it appears incremental as it applies an existing lexicon resource to improve results.
The paper tackled sentiment analysis by using Sentiwordnet to compute polarity scores for words, enhancing classification performance at sentence and document levels.
The task of sentiment analysis of reviews is carried out using manually built / automatically generated lexicon resources of their own with which terms are matched with lexicon to compute the term count for positive and negative polarity. On the other hand the Sentiwordnet, which is quite different from other lexicon resources that gives scores (weights) of the positive and negative polarity for each word. The polarity of a word namely positive, negative and neutral have the score ranging between 0 to 1 indicates the strength/weight of the word with that sentiment orientation. In this paper, we show that using the Sentiwordnet, how we could enhance the performance of the classification at both sentence and document level.
