Our proposed approach first identifies groups of words that have similar syntactic and sentimental roles, called SIGs (similar syntactic and sentimental information groups). ...
We then build HMMs using the SIGs as hidden states for the initialization. The SIGs function as the prior knowledge of formative elements of sentimental sentences for HMMs. ...
We first build positive syntactic-sentimental feature vectors of unigrams with positive instances. Then we apply GMMs to group unigrams into SIGs. We build SIGs for the negative HMM in a similar way. ...
