What is LSI?

Latent Semantic Indexing (LSI) is a system used by Google and other major search engines (Update: read here, thanks for the Tweets, guys) The contents of a webpage are crawled by a search engine and the most common words and phrases are collated and identified as the keywords for the page.
 
Latent semantic indexing (LSI) is an indexing and repossession method that makes use of mathematical technique called singular value decomposition (SVD) to classify patterns in the relationships between the terms and concepts confined in an unstructured collection of text. LSI is founded on the principle that words that are used in the same contexts incline to have similar meanings. One of the main features of LSI is its ability to mine the conceptual content of a body of text by creating associations between those terms that occur in similar contexts.
 
Latent semantic indexing adds an important step to the document indexing process. In addition to recording which keywords a document contains, the method examines the document collection as a whole, to see which other documents contain some of those same words. LSI considers documents that have many words in common to be semantically close, and ones with few words in common to be semantically distant.
 
Latent Semantic Indexing is a part of the google algorithm. LSI is based on the principles that words that are used in the same contexts tend to have similar meanings. It is a mathematical calculation that can be used by Search engines to determine the relevance of content of the keywords.
 
(LSI) may be a system employed by Google and different major search engines (Update: browse here, thanks for the Tweets, guys) The contents of a webpage are crawled by an exploration engine and therefore the most typical words and phrases are collated and known because the keywords for the page.

Large-scale integration (LSI) is the process of integrating or embedding thousands of transistors on a single silicon semiconductor microchip. LSI technology was conceived in the mid-1970s when computer processor microchips were under development.

LSI is no longer in use. It was succeeded by very large-scale integration (VLSI) and ultra large-scale integration (ULSI) technologies.
