In order to solve the problem of fuzzy semantic in social annotation system, this paper analyses the relation among users, resources and tags, introduces latent semantic analysis probabilistic PLSA model. By extending PLSA model,the annotation is mapped to a finite-dimensional latent semantic space, and the collection of latent semantic of annotation is obtained by clustering. This discovery method improves the satisfaction of user’s actual need for resource in social annotation system. Finally, experimental results show the effectiveness of the proposed method.
