Ambiguity of tag may influence users' efficiency in Folksonomy systems.PLSI model was used to analyze semantic tags,through the training of TEM algorithm to get the conditional probability of latent variables,and to generate probability vectors.On that basis,this paper proposed HAK-mediods clustering algorithm to cluster probability vector.The experimental results turn out that HAK-mediods clustering algorithm enhances the clustering performance than traditional clustering algorithm.
