| "[...] a controlled and dynamic vocabulary encompassing a specific area of knowledge. In its structure, it highlights the relationships between terms or descriptors - hierarchical, synonymous, and others - which, together, constitute the indexing language." |
(IBICT, 1984, p. 5) |
| "[...] the vocabulary of an indexing language that is controlled and formally organized to make explicit the a priori relationships between concepts (e.g., broader than... or more specific than...). It describes the indexing language as: 'a controlled set of terms extracted from natural language and used to briefly represent the subjects of documents.'" |
(ISO 2788, 1986) |
| A thesaurus is a vocabulary of terms that are generically and semantically related to a specific area of knowledge. |
(Motta, 1987) |
| "[...] A dynamic documentary language containing terms that are semantically and logically related, comprehensively covering a domain of knowledge."”. |
Gomes, 1990, p. 16) |
| [...] A structured list of concepts intended to univocally represent the content of documents and queries within a specific documentary system [...] includes descriptors, non-descriptors, hierarchical and associative relationships, and linguistic equivalences." |
(Van Slype, 1991, p.23-24) |
| "[...] A documentary language constructed through conceptual units extracted from the formal language of a specific area of scientific or technical knowledge. Its structure suggests the idea of a system, as the concepts are related to each other and are represented by terms. Each term, in turn, is linked to another term through relationships of equivalence, hierarchy, or association. The thesaurus, used for the organization and retrieval of information, constitutes an important '[...] tool to support scientific research in knowledge areas.'" |
(Fujita, 1998) |
| "[...] A documentary language that standardizes the concepts of a specific area through terms expressed in logical-semantic structures." |
(Tálamo; lara; Kobashi, 1992) |
| [“...] A controlled vocabulary of an indexing language, formally organized to make explicit the a priori relationships between concepts (e.g., generic and specific)” |
(UNESCO, 1993, p. 14) |
| "[...] A specialized, standardized, post-coordinated vocabulary used for documentary purposes, where the linguistic elements that compose it, whether simple or compound terms, are syntactically and semantically related to each other." |
(Currás, 1998) |
| "[...] A thematic or faceted classification system, whose basic structure is formed by a relationship of descriptors representing or describing authorities or thematic content. [...] Through linguistic, semantic units and their relationships, extracted from the formal language of a discipline or specific area of knowledge, it becomes a tool for the representation and retrieval of information." |
(Naumis Peña, 2000) |
| "[...] An appropriate tool for transmitting concepts and their reciprocal relationships, similar to what occurs with terms expressed in the language of documents." |
(Dodebei, 2002, p. 67) |
| "[...] As a function - 'an instrument of terminological control that allows the natural language of documents, indexers, and users to be translated into a more rigid "systemic language" (documentary language, information system language).' As a structure - 'a controlled and dynamic vocabulary of terms that are semantically and generically related, covering a specific field of knowledge.” |
(ANSI/NISO-Z39.19, 2005, p. 9) |
| “[...] Post-coordinated combinatorial structures, consisting of terms - linguistic units derived from both specialized language and natural language - called descriptors, endowed with syntactic-semantic relationships, referring to specialized scientific domains, allowing thematic representation of document content and information retrieval” |
(Boccato; Ramalho; Fujita, 2008, p. 201) |
| “A type of knowledge organization system integrated with analyzed and standardized terms that maintain semantic and functional relationships with each other. The thesaurus is organized under strict terminological control to provide an ideal tool for storing and retrieving information in specialized areas. [...] “ |
