Latent Semantic Indexing

Definition

Latent Semantic Indexing (LSI) is a technique used in natural language processing and information retrieval that analyzes relationships between a set of documents and the terms they contain. It identifies patterns in the use of words and phrases to understand the context and meaning behind them, enhancing search engine algorithms and improving the relevance of search results.
