In the mobile network, user can share their trip stories at any time and place, the massive user data can provides an opportunity to mining users' travel preferences. Tourism recommendation has been studied by lots of researchers, although they took into account the social relation of users and the need of travelers, but if multi-dimensional social information and the seasonality of tourism service are considered, it may lead to better personality efficiency for tourism recommendation system. In this paper, we propose a novel personalized tourism service recommendation model termed GA-LSTM_CSInf, which fused multi-modality travel information include the multi-dimensional social information, time series and tourism service category. The main work is listed as follows:(1)we combined genetic algorithm (GA) and LSTM network for predicting the popularity and score of tourism service.(2) Considering the multi-dimensional social information of users in social networks, we proposed the Explicit Social Influence (ExSoInf) and the Implicit Social Influence (ImSoInf) of users, and then integrated them into SVD algorithm.(3) Calculating user preferences for tourism service categories using matrix factorization technology. And then, the calculation results of the three methods are weighted and summed to obtain a fusion tourism service recommendation algorithm (GA-LSTM_CSInf). We conduct a comprehensive performance evaluation for our fusion recommendation algorithm using real-world dataset collected from Yelp. Experimental results show that our method achieves significantly superior recommendation quality compared to other state of art recommendation methods.
