- Abstract:
-
Affective computation has received more and more attentions in the field of artificial intelligence; however, the calculation of affective lexicon ontology is a requirement for affective computation of texts. At present, most emotional lexicons are obtained by manual methods. The automatic acquisition of emotional lexicons has become an urgent task that needs to be addressed. This paper presents an automatic acquisition method for emotional lexicons. The authors analyzed the general syntactical rules of emotional lexicons, such as the rules of overlapping words, then rules governing how these acquired emotional words were modified by privatives and degree adverbs. Then we used the conditional random fields (CRF) model to acquire emotional words based on the general rules. Finally, we analyzed the effects of various syntax rules on the automatic acquisition of emotional vocabulary. Experiments were done and the results showed that the proposed method is effective for automatic acquisition of emotional words.
