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.

In 2012, pLSA has also been used in the [[bioinformatics]] context, for prediction of [[gene ontology]] biomolecular annotations.<ref>{{Citationcite web|
