LSA is used in natural language processing applications, including chatbots and automatic translation services, and is capable of emulating human-like patterns and behaviors, such as word sorting and category assessment.{{Cite journal |last=Foltz |first=Peter W. |date=1996-06-01 |title=Latent semantic analysis for text-based research |url=https://link.springer.com/article/10.3758/BF03204765 |journal=Behavior Research Methods, Instruments, & Computers |language=en |volume=28 |issue=2 |pages=197–202 |doi=10.3758/BF03204765 |issn=1532-5970}} LSA has found applications in data mining, recommender systems, and business intelligence tools. This research has also been useful in the development of Latent Dirichlet Allocation (LDA) and probabilistic models, which are used in topic modelling and semantic analysis.

In 1988, Deerwester co-authored a research paper on latent semantic analysis (LSA).{{Cite book |last1=Dumais |first1=S. T. |last2=Furnas |first2=G. W. |last3=Landauer |first3=T. K. |last4=Deerwester |first4=S. |last5=Harshman |first5=R. |chapter=Using latent semantic analysis to improve access to textual information |date=1988 |title=Proceedings of the SIGCHI conference on Human factors in computing systems - CHI '88 |url=https://scholar.google.com/citations?view_op=view_citation&hl=en&user=r4NPfVkAAAAJ&citation_for_view=r4NPfVkAAAAJ:u-x6o8ySG0sC |language=en |location=Washington, D.C., United States |publisher=ACM Press |pages=281–285 |doi=10.1145/57167.57214 |isbn=978-0-201-14237-2}} The paper proposed an alteration to information retrieval systems that would process textual information by deriving a semantic structure. Notably, the techniques introduced in the paper allowed search engines to retrieve relevant documents that lacked exact keywords. This was done by accounting for polysemy and synonymy.{{Cite journal |last1=Hurtado |first1=Jose L. |last2=Agarwal |first2=Ankur |last3=Zhu |first3=Xingquan |date=14 April 2016 |title=Topic discovery and future trend forecasting for texts |journal=Journal of Big Data |volume=3 |doi=10.1186/s40537-016-0039-2 |doi-access=free}}
