Due to the random of mass tagging user-generated tags and non-regularity of confusion arising from the label, this paper introduces the Probabilistic Latent Semantic Analysis (PLSA) algorithm for latent semantic indexing analysis,gets the label set of specific resources under the theme and provides an effective approach for the network information organization and the user’s access. By taking the user annotation information through Delicious site,the paper substantiates that the PLSA approach can achieve a good result for the subjects of particular resources.
