Latent Semantic Indexing. Also known as LSI is kind of complicated. I honestly don't fully understand what semantic means. Or latent for that matter. All I know is that is has something to do with google. When you google specific words they run through the google search engine. Latent Semantic Indexing has something to do with the search engine. When you google a couple words, the google search engine is going to run those words through the system and will pull up web pages according to the words that you put into your google search engine.
When you use google the google search engine will look at key terms in all of the web page articles. Performing Latent Semantic indexing, the google search engine will find the best pages according to the LSI terms connected with the words you put into the google search engine. Articles and other pages will all be given a specific order when you type in certain key terms. These articles use Latent Semantic indexing to find the article or page that has the terms that you put into google plus a good amount of words written in the article. This prevents a web page that all it says is "how to fix a flat tire" from popping up at the top of your google search when you type in "how to fix a flat tire" into the google search engine.
Latent Semantic indexing doesn't always have to be the same as the keywords that people are typing in. In fact there are a lot of LSI terms that aren't very similar to the actual keywords. These LSI words can vary dramatically depending on what the keywords are. They will have be related to the key terms in some way, but Latent Semantic indexing terms are going to vary in similarity.
There will be some things that make a lot of sense. Let's say you google "how to change a flat tire", some of the LSI terms that pop up are going to be terms like tire, change, or how. The Latent Semantic indexing terms usually are pretty related to the key terms. However, sometimes you will get a LSI terms like car, garage, repair... words like this. See how the Latent Semantic Indexing terms are visibly related but are different from the key term "how to change a flat tire"? This is what LSI terms are.
This is what the google search engine is going to be looking for when you type in "how to change a flat tire" Of course they are going to have the Latent Semantic Indexing terms like flat tire, change, how be the most important. But the google search engine is still going to look for more terms in articles that are related to the original key words. The google search engine is a very complex thing, but once you understand the concept of Latent Semantic indexing you will be able to find things on google much easier. Understanding Google
