摘要： 基于时间和空间感知,提出一种新的活动推荐方法。考虑用户的社会关系,通过构建用户、地点、时间、活动、朋友关系异构信息网络,采用随机游走算法获取推荐活动。实验结果表明,与流行活动推荐方法和基于社会关系的活动推荐方法相比,该方法能获得较好的推荐效果。

Abstract: A new recommendation method is proposed based on time and space perception.Considering the user's social relationship,the random walk algorithm is used to get the recommendation activity by constructing the user,location,time,activity,and the information network of friends.Experimental results show that this method can get better results compared with the popular activity recommendation method and the social relation activity recommendation method.

Key words: activity recommendation, random walk, social network, heterogeneous network model, time and location-aware
