Search engine optimization (SEO) professionals always strive to optimize the websites so that the websites show up early on the SERP (search engine results page). It always helps to know the search engine technology that are used by search engines and that is when we come across the term LSI. LSI stands for Latent Semantic Indexing and is the technology that makes it possible for us to search online and get good relevant and the required results from the Internet.
Everyone has certain expectations when they type in keywords on the search text box. With the ever growing volume of content made available on the Internet, one realizes that the search engine is a great super librarian and the results that come out are not just at random but always arranged in the best available sequence and manner. There are three essential qualities that any search engine must have to give out a good search result. They are,
- Good recollection
- Good precision
- Good order
Yet from where exactly does the LSI originate? Well actually it is an information retrieval application of the superior LSA (Latent Semantic Analysis) technology. By definition LSA is a technique in natural language processing, in particular in vectorial semantics, of analyzing relationships between a set of documents and the terms they contain by producing a set of concepts related to the documents and terms.
How is LSI different from other technologies? Well this superior LSI can investigate the semantic relationships within a text to decide as to how relevance and consistent it is to the different component parts. It is a precise technique with the power to filter information and prevent spamming.
