Definitions

• Maps relationships between each word and every other word in large sets of documents and then associates words based on the context in which they are used. Two techniques can be used to perform concept searches: the use of a manually constructed thesaurus which relates certain words to others or semantic indexing, a fully automated methods to show associations among words based, in part, on statistical analysis of the occurrence of proximity of certain words to others. ^[1]
• Also called "thesaurus" or "related" searching; sometimes called "synonym searching." Searches that provide other words similar or close in meaning to the primary word. ^[2]
