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 [[Genegene Ontologyontology]] biomolecular annotations.<ref>[http://home.dei.polimi.it/chicco/Wcci2012_DavideChicco_et_al.pdf ''"Probabilistic Latent Semantic Analysis for prediction of Gene Ontology annotations"'', Marco Masseroli, Davide Chicco, Pietro Pinoli.
