IE based SMS semantic orientation recognition

This paper is a grope research on applying the technology of information extraction (IE) in the field of information content security and the focus is semantic orientation recognition for short message service (SMS). An experimental SMS monitoring system will be introduced, in which rules based and hidden Markov model (HMM) based IE patterns are integrated to recognize the semantic orientation of Chinese SMS in two specific domains. Testing results have shown that the performance is good and the method is feasible and promising.
