- Abstract
- This paper is aimed at assessing the potential of interoperable knowledge organization systems to respond to search strategies in order to retrieve information from databases in the areas of health and biomedicine. An analysis was done on the semantic consistency of synonym grouping of a term selected from the Metathesaurus, the Unified Medical Language System of the National Library of Medicine, based on the characteristics of equivalence proposed in ISO 25964: 2: 2011 and based on the following categories: semantic, morphological, syntactic and typographical variations. This paper highlights the importance of understanding the results of automatic mapping as well as the need for characterization, evaluation and selection of equivalences for preparation of consistent search strategies and presentation of search results in scientific work methodologies.

- Abstract
- This paper explores the relationships between natural language lexicons in lexical semantics and thesauri in information retrieval research. These different areas of knowledge have different restrictions on use of vocabulary; thesauri are used only in information search and retrieval contexts, whereas lexicons are mental systems and generally applicable in all domains of life. A set of vocabulary requirements that defines the more concrete characteristics of vocabulary items in the 2 contexts can be derived from this framework: lexicon items have to be learnable, complex, transparent, etc., whereas thesaurus terms must be effective, current and relevant, searchable, etc. The differences in vocabulary properties correlate with 2 other factors, the well-known dimension of Control (deliberate, social activities of building and maintaining vocabularies), and Syntagmatization, which is less known and describes vocabulary items' varying formal preparedness to exit the thesaurus/lexicon, enter into linear syntactic constructions, and, finally, acquire communicative functionality. It is proposed that there is an inverse relationship between Control and Syntagmatization.

- Abstract
- In the post-war period before computers were readily available, urgent demand for scientific and industrial develop-ment stimulated research and development (R&D) that led to the birth of the information retrieval thesaurus. This article traces the early history, speciation and progressive improvement of the thesaurus to reach the state now conveyed by guidelines in inter-national and national standards. Despite doubts about the effec-tiveness of the thesaurus throughout this period, and notwith-standing the dominance of Google and other search engines in the information retrieval (IR) scene today, the thesaurus still plays a complementary part in the organization of knowledge and in-formation resources. Success today depends on interoperability, and is opening up opportunities in linked data applications. At the same time, the IR demand from workers in the knowledge society drives interest in hybrid forms of knowledge organization system (KOS) that may pool the genes of thesauri with those of ontologies and classification schemes.

- Abstract
- The information retrieval thesaurus emerged in the 1950s, settled down to a more-or-less standard format in the 1970s and has continued to evolve marginally since then. Throughout its whole lifetime, doubts have been expressed about its efficacy with emphasis latterly on cost-effectiveness. Prolonged testing of different styles of index language in the 1970s failed to settle the doubts. The arena occupied by the debate has moved from small isolated databases in the post-war era to diverse situations nowadays with the whole Internet at one extreme and small in-house collections at the other. Sophisticated statistical techniques now dominate the retrieval landscape on the Internet but leave opportunities for the thesaurus and other knowledge organization techniques in niches such as image libraries and corporate intranets. The promise of an ontology-driven semantic web with linked data resources opens another opportunity. Thus much scope remains for research to establish the usefulness of the thesaurus in these places and to inspire its continuing evolution.
