LSI is short for latent semantic indexing. This refers to different words that have the same or similar meanings (or words that are otherwise related). For example, “housebreaking a dog” and “housetraining a puppy” are two entirely different phrases, but they mean about the same thing.

The reason this is important is because Google analyzes WebPages using LSI to help it return the most relevant results to the user.

For example, a page that has the keyword “housebreaking a dog” but NO other similar words (like housetraining, paper training, potty training, puppy, dogs, puppies, etc) probably really isn’t about housebreaking. End result: Google won’t rank it as high as a web page that does include a lot of relevant, related terms.

What does this mean to you? When you create a web page around a keyword, be sure to also include the keyword’s synonyms and other related words.

Pure LSI analysis isn't scalable enough to handle the volumes of data that Google processes. Instead they use more streamlined and scalable content analysis algorithms that have some basis in LSI and other related technologies. It also appears that this analysis is ongoing and not just a one time run through the system.

Cliff Notes: Don’t write content that a drunk 4th grader would be ashamed of. Spend the extra couple of minutes to write decent stuff and you’ll be fine.

LSI is a methodology involving statistical probability and correlation that helps deducing the semantic distance between words. It's obviously a complex methodology but can be easily applied to understand the relation between certain words in a paragraph or in a document. This methodology is being used while indexing a page in the search engine's database.
Hope this help ...

LSI is a newer mathematical way to search through a large group of documents and find those with similar content. It is based on a mathematical algorithm that removes all non-content words and then compares the remaining content to other documents. Unlike SEO, the larger the database the better LSI technology works.

In my opinion LSI refers to some methodogy which helps in improving the rankings in most of the search engines. It is just acts as a concepts not as a technique. It is basically related to artificial intelligent.
