Abstract: Focusing on the discordance between text comments and ratings, a synthetical evaluation generating algorithm is proposed by using sentiment polarity analysis, and a trust computation model is constructed based on the HMM. The optimal hidden trust state sequence is found according to the observation sequence which is a synthetical evaluation sequence. The probability of an entity in the most credible state is the trust value. In this model, the precision of trust computation is improved, and trust dynamics is reflected. Finally, satisfactory results are obtained with simulated experiments.

Key words: hidden Markov model, sentiment polarity, comments, trust
