Product Sentiment analysis using support vector machines based on opinion-based texts


 

Abstract:
 

There are a number of challenging aspects in recognizing the favorability of opinion-based texts, the task known as sentiment analysis. Opinions in natural language are very often expressed in subtle and complex ways, presenting challenges which may not be easily addressed by simple text categorization approaches such as n-gram or keyword identification approaches. Although such approaches have been employed effectively, there appears to remain considerable room for improvement. Moving beyond these approaches can involve addressing the task at several levels. Negative reviews may contain many apparently positive phrases even while maintaining a strongly negative tone, and the opposite is also common.

This presentation will concentrate on the implementation methods of SVM.
