What is LSI?

The full form of LSI is "Latent Semantic Indexing".LSI or Latest Semantic Indexing is an informational retrieval system that depends on a technique used to process natural language into a mathematical form that the computer can understand and process.

Some times we are using like this keyword like "apple", but search engine dosn't know what you are really seaching, apple firm or apple juice.So we have specify by our keywords we are seaching.The solution that handles this is what is often referred to here as a SE algorithm. An algorithm is mathematical formula for solving complex problems.

so, we can say that LSI is a mathematical way for searching a large group of documents and those with similar content.
