Latent Semantic Indexing is the prctice of a search engine gathering the dcuments that match the search using bth the search keywords and related kywords. Such a technique provides more dcuments while keeping most of those dcuments to the proper subject.

In the old styl of indexing or search engine ptimization, only those articles or documents tht contain the keywords noted in the sarch would be able to be plled up using such a search. Usng these techniques, more documents are plled relating to the keywords, which mkes the system appear more intelligent whle providing more information to the ser.

An example of this would be to use the kyword Dog Grooming. With traditional search ngines, only those articles that containing the wrds dog grooming would be brought frward for notice. Using the LSI not nly would the articles containing the wrds dog and grooming appear, but fter them, words such as pets and cre would also be keywords in ther articles or documents.

While this Ltent Semantic Indexing is a great tol, it should be noted that it des not understand the meanings of wrds. For example, Dog Grooming can ventually get words like care, and cre can be care for the nvironment or care for the elder. Thse are not documents that one wuld be interested in if they are loking for Dog Grooming. Although, the LSI systm is very effective at determining the ppropriate documents to bring forward.

The manner that you achieve ths matching of words is quite cmplex. The primary idea of this is to tke a listing of every word in ver article, and go from there. Frst one would get rid of all of the rticles, all of the pronouns, all of the djectives, and all of the fancier wrds such as therefore. This leaves a sries of content words that the systm is able to understand and act pon.
