This paper analyzes and compares the quality of translations of literary works through the analysis and comparison of several machine translation software in common use at present, understands the development status and level of machine translation, and then classifies and summarizes the existing information dissemination models. By comparing the differences between traditional social networks and blockchain social networks and analyzing the information dissemination mode, this paper discusses the shortcomings of machine translation in literary works, and looks forward to the development trend and direction of machine translation in the context of artificial intelligence. A generalized model of social reinforcement is proposed. The results of numerical experiments show that the generalized model proposed in this paper has a good explanation for the complex infection mechanism, and the optimal proportion of the number of seed nodes can promote the information dissemination based on the complex infection mechanism.
