基于语义倾向计算器的情感分析方法
Sentiment analysis method based on semantic orientation calculator
摘要
Abstract
For the polarity and strength of unknown sentiment words cannot be calculated and classified effectively in traditional lexicon-based classifiers. The EM-SO algorithm was proposed based on expectation maximization for constructing and updating sentiment lexicon. Negative and intensifying components were designed upon SO-CAL for capturing the combined effects of appraisal words and their modifiers. Experimental results showed that the EM-SO algorithm and designed components outperform SO-CAL obviously for the calculation performance of the polarity and strength of sentiment words on review sets and can be applied to the subjective classification task and so on.关键词
