In this paper, we proposed a perspective Hierarchical Dirichlet Process (pHDP) model to deal with user-tagged image modeling. The contribution is twofold. Firstly, we associate image features with image tags. Secondly, we incorporate the user"s perspectives into the image tag generation process and introduce new latent variables to determine if an image tag is generated from user"s perspectives or from the image content. Therefore, the model is capable of extracting both embedded semantic
