Research on Construction of Tibetan Emotion Dictionary

Sentiment classification is one of the research hot spots of Natural Language Processing. Compared with English and Chinese, it is hard for Tibetan to do some research of sentiment analysis because of the situation that we lack of related emotion dictionary. Considering there is no semantic dictionary like Hownet in Tibetan and the limited corpus, in this paper we built a comprehensive and efficient polar dictionary by artificial means, including basic dictionary, negative dictionary, degree-adverb dictionary and turning words dictionary.
