Abstract
In order to improve the performance of personalized tag recommendation method
the Gibbs sampling inference based RTM model for Micro-blog personalized label recommendation was proposed. Firstly
we used the user topic distribution as the representative of the user with Top-k similar for the potential local information in micro-blog
Then we calculated the frequency of all tags appearing in these users
and recommended the most relevant tags with the user. Secondly
in order to explore the potential theme information
we named the micro-blog tags by using the implicit relation model
which could greatly improves the influence of the joint modeling on the latent topic generation tags
and finds out the relationship between the global tags and the topic; Finally
the experimental results show that the proposed method is superior to the selected TF-IDF
RTMSA and other classical label recommendation algorithm
and verify the effectiveness of the proposed algorithm.
