Fu Wei · Beijing Youdian Xueyuan xuebao · 2012
The forgoing experiments have shown that the method of opinion words identification with non-propagation is extremely limited on social medium information.A method of opinion words expansion identification based on dependency parsing is presented.Through new words and phrases discovery,pruning and merger on dependency tree,the opinion words are expanded.A key advantage of the proposed method is that it can expand words in direct dependency and indirect dependency.Experiments verify the feasibility of this method.
