In this paper, we develop a fraud detection system based on real-time messaging content analysis. An integrated platform consisting of natural language processing, matrix pre-processing, content analysis via latent semantic model and cosine similarity is proposed for fraud detection. We collect a series of fraud events in Taiwan and construct major analysis modules of the proposed fraud detection system. Moreover, a mobile application is built for Android based smartphones as the content retrieval and alert notification for doubtful logs and fraud events.
