Abstract Based on the dataset of authoritative journal in the field of library and information science,this paper tries to apply Probabilistic Latent Semantic Analysis (PLSA) algorithm to process documents representing expertise,in order to locate the research areas of experts in this field. The experiment results show that this method is feasible and achieves good results.
