We conclude that the passive get in get-passive equals to a lexical verb considering its syntactic representation and the get-passive represent itself as an actional passive of which the subject is responsible for the event denoted by the action.Concerning the interpretation, we consider get-passive as a reflexive ECM(exceptional case-marking)-construction.展开更多

There has been a significant progress in this area recently, especially the method based on conditional random field （CRF）. However, this method only takes lexicon-related features into consideration and does not excavate the implied syntactic and semantic knowledge. We propose a novel approach which incorporates domain lexicon with groups of syntactical and semantic features. The approach acquires domain lexicon through a novel way which explores syntactic and semantic information through Part- of-Speech, dependency structure, phrase structure, semantic role and semantic similarity based on word embedding. And then we combine the domain lexicon with opinion targets extracted from CRF with groups of features for opinion targets extraction. Experimental results on COAE2014 dataset show the outperformance of the approach compared with other well-known methods on the task of opinion targets extraction.展开更多
