Abstract

The invention provides a restaurant recommendation method based on online reviews and context awareness, and relates to restaurant recommendation. A context classification model is trained from onlinereviews; a feature extraction model is trained from the online reviews; online processing is conducted for user queries. On the one hand, according to the characteristics of online review and score data, positive / negative opinions expressed by the online reviews under what circumstances can be effectively distinguished, and features of which restaurants are preferred by users under different circumstances are accurately extracted out; on the other hand, according to the user's query requirements, the underlying context requirement can be inferred, the optimal restaurant list is recommended for users according to an efficiency module, the method is a recommendation method high in precision and good in generalization performance, and the user experience can be greatly improved.
