The Thesaurus of General Greek Terms (with terms also provided in English) was published by the National Documentation Centre (EKT) and serves as a tool for documentation, indexing, and information retrieval. It is a structured and curated vocabulary that clearly presents both hierarchical (vertical) and associative (horizontal) relationships between concepts, thereby supporting users in retrieving more comprehensive and relevant results. The thesaurus enables users searching for a concept to identify related terms with broader, narrower, equivalent, or otherwise associated meanings. In this way, it enhances conceptual understanding and reduces the number of separate searches required within a database.
