It indexes the electronic design notebooks by using manually generated thesauri, that is, collections of related terms. This is reflected in the differences between monolingual and bilingual dictionaries, and thesauri, which split senses along different lines. Some of them are encoded in electronic thesauri and dictionaries. There are some researchers who have tried to build thesauri or taxonomies to classify the documents. While richer ontological knowledge than thesauri is used, source descriptions have no semantic knowledge. These include knowledge based approaches that use multilingual dictionaries and thesauri, and corpus based approaches. The use of controlled vocabularies, or thesauri, has been fundamental to document indexing in library science. Domain ontologies and thesauri are required to define domain-specific terminologies. To evaluate the results, he measured the overlap of the results of each technique against existing hand-created repositories of semantic information, such as thesauri and dictionaries. Classification-based approaches take advantage of the domain thesauri or taxonomies to capture concepts from the document, and hence, are capable of improving the precision and recall. Thesauri thus serve many of the same functions for people that ontologies are designed to serve for software agents. Hundreds of thesauri have been produced since then, perhaps thousands.

Controlled vocabularies (dictionaries and thesauri), and ontologies allow broader terms, narrower terms, and related terms to be incorporated into queries.

For each concept, the thesauri provided the usual lexical and semantic information: preferred labels, synonyms and notes, broader and related concepts, etc. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
