Orientation analysis for Chinese blog text based on semantic comprehension

Blog has been accepted by more and more people as a popular information and cultural carrier.Orientation analysis for blog text also has become a hot spot in the field of information mining.The previous researches of text orientation mainly focus on plain text or news comments.A method of orientation analysis for blog text based on semantic comprehension was proposed according to the characteristics of blog text.Firstly,a Chinese basic emotional lexicon dictionary based on the HowNet emotional word set was constructed and the emotional value of Chinese emotional words was calculated on the basis of the similarity of Chinese words.Then,the adverbs and its influence on identification of text orientation in the semantic level were analyzed.Finally,the results were amended by using bloggers' language style factors and then the sentimental classification for blog text was realized.The experimental results show that the proposed method can effectively judge the blog text sentimental preference.
