Embodiment Construction

[0059] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0060] The microblog social network information recommendation method based on finite node drive provided by the present invention can obtain an approximately optimal set of drive nodes, so that the recommended information can spread in the microblog network to approximately the maximum breadth. This method comprehensively considers the connection relationship of users in the microblog social network, user forwarding behavior and interest in topics, etc., designs a suitable network mathematical model, and proposes an improved PageRank algorithm, which is further combined with dynamic Bayesian network Reasoning calculations accurately measure the breadth of information dissemination, and on this basis select the set of driving nodes with the strongest information dissemination capabilities.

Abstract

The invention discloses a micro-blog social network information recommendation method based on limited node drive. Approximately optimal drive node sets can be obtained, then, after being driven by the drive node sets, recommendation information can be spread in a micro-blog network to achieve the approximately maximum extent. Connecting structures among users, distribution of interest of the users in topics and forwarding behaviors of the users are taken into overall consideration to select the approximately optimal drive user node sets, the spreading extent of recommendation information or topic information issued by the drive node sets is approximately maximum.

Description

technical field [0001] The invention belongs to the technical field of online social networks, and relates to a microblog social network information recommendation method based on limited node drive. Background technique [0002] In recent years, the emergence of new network application services such as microblogs, blogs, and forums has profoundly changed the way people communicate information, and has become an important platform for people to obtain and disseminate information. The resulting online social network (Online Social Networks, OSN) has become a current research hotspot. Microblog is one of the typical representatives of online social networks, and has become an important information exchange platform and public topic dissemination platform. [0003] Online social network research mainly involves network structure and user behavior analysis, information dissemination modeling, and content recommendation. At present, content recommendation research focuses on di...
