Chinese micro-blog emotional analysis method based on semantic rules and expression weighting

  • Received Date: 2019-10-08
  • Aiming at the problem that the current Chinese micro-blog emotional analysis methods were not comprehensive, which led to poor sentiment analysis results, a Chinese micro-blog emotional analysis method based on semantic rules and expression weighting was proposed.On the basis of using traditional emotion dictionary to analyze the emotion tendency of Chinese micro-blog, negative words, degree adverbs and network neologisms were incorporated into the general emotion dictionary.According to the unique language characteristics and sentence pattern characteristics of Chinese micro-blog text, the method of emotional analysis from words to clauses and then to complex sentences was adopted to analyze the whole Chinese micro-blog.Expression weighting and semantic rules were used to perform weight summation to determine emotional tendency.The experimental results showed that compared with the other three Chinese micro-blog emotional analysis methods,the proposed method was more effective.It had an average precision rate of 78.4%, an average recall rate of 75.2%, and an average F value of 76.7%.
