Line 21: PLSA has applications in [[information retrieval]] and [[information filtering\|filtering]], [[natural language processing]], [[machine learning]] from text, and related areas. It is reported that the [[aspect model]] used in the probabilistic latent semantic analysis has severe [[overfitting]] problems.<ref>{{cite journal\|title=Latent Dirichlet Allocation\|journal=Journal of Machine Learning Research\|year=2003\|first=David M.\|last=Blei\|author2=Andrew Y.
