Definition
Latent Semantic Indexing (LSI) uses word associations (words related to the subject of a search as opposed to the actual keywords entered) to help search engines know more accurately what a page is about.[1][2]
See Wikipedia on latent semantic indexing for more in-depth information about the method’s history and science.
