Abstract: To deal with the issues like existing common data sparseness in weibo social network and the phenomena
of cold start, this paper puts forward a two-stage clustering based on the recommendation algorithm
GCCR. At the same time, because of fuzziness of graph clustering, this thesis retains a certain diversity in the
process of user interest clustering, so as to avoid convergence too fast when cold start. This method is verified
through the real social network data, and the experimental results show that this algorithm can effectively
solve the problems such as data sparseness and cold start phenomenon.
