Google, as a search engine, employs various algorithms and techniques to understand user queries and deliver relevant search results. One of these techniques, which is related to the concept of Latent Semantic Indexing (LSI), is called Latent Semantic Indexing Keywords (LSI Keywords).
By using LSI, search engines and information retrieval systems can provide more accurate and relevant results to user queries. It can identify related terms and concepts, even if they are not explicitly mentioned in the search query, which helps in improving the precision of search results. LSI also helps in overcoming the limitations of traditional keyword-based approaches, such as synonymy and polysemy, by understanding the contextual relationships between words.
