Abstract

The invention provides a method for establishing a MicroBlog user interest inference model. The method comprises an interest label calculation model, an interest model used for MicroBlog text content extraction and a blogger interest point model used for blogger social relationship extraction, and the three models are fused through a model fusion strategy to obtain the final MicroBlog user interest inference model. The method combines personal information, MicroBlog contents and the social relationship, adopts a USER strategy that all MicroBlog contents of the same blogger are mixed by aiming at the sparsity problem of the MicroBlog contents, mines an implicit theme of the MicroBlog by a LPA (Label propagation algorithm), puts forwards a social label propagation algorithm on the basis of a network formed by blogger attention, and calculates influence on the blogger by various interest labels. The method exhibits good identification capability and information filtering capability, and filters false information to identify false bloggers before recommendation is carried out, so that the recommendation quality and accuracy of a recommendation system can be improved, and better experience is brought for the blogger.
