SEO and LSI (Latent Semantic Indexing)
Search engine optimization (SEO) professionals always strive to optimize their websites so that they show up early on the SERP (search engine results page). LSI or Latent Semantic Indexing is the technology that makes it possible for us to search online and get good required and relevant results from the Internet every single time. It always helps to know the search engine technology that is used by search engines.
What do we know about the origins of LSI? LSI is actually an information retrieval application of the superior LSA (Latent Semantic Analysis) technology. By definition Latent semantic analysis (LSA) is a technique in natural language processing, in particular "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. And in the context of its application to information retrieval, it is sometimes called LSI (latent semantic indexing).
Everyone has certain expectations from the search engines when they type in keywords on the search text box. With the ever growing volume of content being made available on the Internet, one realizes that the search engines are great super librarians and the results that come out on every single search are not just at random but always arranged and delivered 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. These are,
Good recollection
Good precision
Good order
How is LSI different from other technologies? Well this superior LSI can investigate the semantic relationships within a text to decide as to how relevant and consistent it is to the different component parts. It is a precise technique with the power to filter information and prevent spamming.
