- Abstract:
-
The semantic orientation of words is the foundation of sentiment analysis. Current methods to compute semantic orientation of words are mostly based on reference words, while words belonging to the granularity category, including various sentiment orientation concepts, affect the analytical precision and efficiency. In this paper, a new method of semantic orientation computing was proposed based on the reference concepts using the HowNet tool to analyze the tendency. The clustering algorithm KMediods was used to search for the reference concepts. The experimental results show that the conceptbased method outperforms the wordbased method.
