Abstract: With the advent of the era of social network, the types of social network gradually cover different user groups. The potential mining of social network needs of different user groups is the current research hotspot. Based on the artificial intelligence recommendation algorithm, this paper constructs the multi-level circle structure of family social network, and proposes an intelligent recommendation algorithm of family and relatives. Based on the intelligent algorithm and the social mode of family, a family social network system that is composed of personal information module, basic function module, family information module, application service module and open API module is designed. The results show that when the amount of data is more than 10000, the execution efficiency of the intelligent recommendation algorithm is about three times that of the non intelligent recommendation algorithm, and the number of cluster nodes has a significant impact on the execution efficiency. In addition, the social system under the intelligent recommendation algorithm is of good effect, which shows that the intelligent recommendation algorithm has high practicability. This research provides the data support of social network service mechanism and verifies the market potential of family social service through the research of data-based recommendation algorithm for family social service and the quantitative verification of algorithm execution efficiency.
