Abstract
Aspect based opinion mining investigates deeply, the emotions related to one’s aspects. Aspects and opinion word identification is the core task of aspect based opinion mining. In previous studies aspect based opinion mining have been applied on service or product domain. Moreover, product reviews are short and simple whereas, social reviews are long and complex. However, this study introduces an efficient model for social reviews which classifies aspects and opinion words related to social domain. The main contributions of this paper are auto tagging and data training phase, feature set definition and dictionary usage. Proposed model results are compared with CR model and Naïve Bayes classifier on same dataset having accuracy 98.17% and precision 96.01%, while recall and F1 are 96.00% and 96.01% respectively. The experimental results show that the proposed model performs better than the CR model and Naïve Bayes classifier.
Highlights
Opinions are the key elements that influence a person’s decision making capability
The proposed model, CR model and Naïve Bayes have been implemented on the movie reviews dataset
For experimental purposes 119 movie reviews have been taken for training and 51 movie reviews have been taken for testing
Summary
Opinions are the key elements that influence a person’s decision making capability. It is natural for people to consult with friends or family whenever they make a decision, and so, to have access to diverse opinions. For marketing, public relations, and political campaign, gathering public and customer opinions has become a profitable business. It has been made possible for everyone to have internet access and express his/her opinion about something in a matter of one click on social networks or other sites [2]. Instead of consulting friends or family, people prefer to read reviews online in order to make a purchase decision about a product or service. The opinions expressed in social networking sites or product review sites have already assisted in reshaping the political and businesses structure. It was social networking sites like Facebook that had changed the political thinking of Arab people in 2011 [1]
