![]() Journal of Systems Science and Systems Engineering 23(2):212–230.Ĭhatterjeei P (2001). Topics and trends of the online public concerns based on Tianya forum. The outcome of this study provides potential implications for online review management and business intelligence of deceptive review identification.Ĭao L, Tang X, (2014). Moreover, the DCWord-M strategy outperforms the DCWord-A strategy in review representation for deceptive review identification. Experimental results on the Spam dataset and the Deception dataset demonstrate that the DCWord-M representation with LR (Logistic Regression) produces the best performances and outperforms state-of-the-art techniques on deceptive review identification. The average-pooling strategy (called DCWord-A) and max-pooling strategy (called DCWord-M) are used to produce review vectors from word vectors. Unlike state-of-the-art techniques in seeking best linguistic features for representation, we use word vectors to characterize contextual information of words in deceptive and truthful reviews automatically. The basic idea is that since deceptive reviews and truthful reviews are composed by writers without and with real experience on using the online purchased goods or services, there should be different contextual information of words between them. This paper proposes a deep learning approach for text representation called DCWord (Deep Context representation by Word vectors) to deceptive review identification. Due to the anonymous and free-for-all characteristics of online forums, it is very hard for human beings to differentiate deceptive reviews from truthful reviews. ![]()
