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. Ng |author3=Michael I. Jordan |volume=3|pages=993–1022|id= |url=http://jmlr.csail.mit.edu/papers/volumep3/blei03a/blei03a.pdf|doi=10.1162/jmlr.2003.3.4-5.993}}</ref>

In 2012, pLSA has also been used in the [[bioinformatics]] context, for prediction of [[gene ontology]] biomolecular annotations.<ref>{{cite journal | vauthors = Masseroli M., Chicco D, Pinoli P | title = Probabilistic Latent Semantic Analysis for prediction of Gene Ontology annotations | journal = Proceedings of IEEE WCCI 2012 - the 2012 IEEE World Congress on Computational Intelligence | pages = 1-8 | date = July 2013 | doi = 10.1109/IJCNN.2012.6252767 }}</ref>
