- 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
- T.1: Today's thesauri are mostly electronic tools, having moved on from the paper-based era when thesaurus standards were first developed. They are built and maintained with the support of software and need to integrate with other software, such as search engines and content management systems. Whereas in the past thesauri were designed for information professionals trained in indexing and searching, today there is a demand for vocabularies that untrained users will find to be intuitive. ISO 25964 makes the transition needed for the world of electronic information management. However, part 1 retains the assumption that human intellect is usually involved in the selection of indexing terms and in the selection of search terms. If both the indexer and the searcher are guided to choose the same term for the same concept, then relevant documents will be retrieved. This is the main principle underlying thesaurus design, even though a thesaurus built for human users may also be applied in situations where computers make the choices. Efficient exchange of data is a vital component of thesaurus management and exploitation. Hence the inclusion in this standard of recommendations for exchange formats and protocols. Adoption of these will facilitate interoperability between thesaurus management systems and the other computer applications, such as indexing and retrieval systems, that will utilize the data. Thesauri are typically used in post-coordinate retrieval systems, but may also be applied to hierarchical directories, pre-coordinate indexes and classification systems. Increasingly, thesaurus applications need to mesh with others, such as automatic categorization schemes, free-text search systems, etc. Part 2 of ISO 25964 describes additional types of structured vocabulary and gives recommendations to enable interoperation of the vocabularies at all stages of the information storage and retrieval process.
T.2: The ability to identify and locate relevant information among vast collections and other resources is a major and pressing challenge today. Several different types of vocabulary are in use for this purpose. Some of the most widely used vocabularies were designed a hundred years ago and have been evolving steadily. A different generation of vocabularies is now emerging, designed to exploit the electronic media more effectively. A good understanding of the previous generation is still essential for effective access to collections indexed with them. An important object of ISO 25964 as a whole is to support data exchange and other forms of interoperability in circumstances in which more than one structured vocabulary is applied within one retrieval system or network. Sometimes one vocabulary has to be mapped to another, and it is important to understand both the potential and the limitations of such mappings. In other systems, a thesaurus is mapped to a classification scheme, or an ontology to a thesaurus. Comprehensive interoperability needs to cover the whole range of vocabulary types, whether young or old. Concepts in different vocabularies are related only in that they have the same or similar meaning. However, the meaning can be found in a number of different aspects within each particular type of structured vocabulary: - within terms or captions selected in different languages; - in the notation assigned indicating a place within a larger hierarchy; - in the definition, scope notes, history notes and other notes that explain the significance of that concept; and - in explicit relationships to other concepts or entities within the same vocabulary. In order to create mappings from one structured vocabulary to another it is first necessary to understand, within the context of each different type of structured vocabulary, the significance and relative importance of each of the different elements in defining the meaning of that particular concept. ISO 25964-1 describes the key characteristics of thesauri along with additional advice on best practice. ISO 25964-2 focuses on other types of vocabulary and does not attempt to cover all aspects of good practice. It concentrates on those aspects which need to be understood if one of the vocabularies is to work effectively alongside one or more of the others. Recognizing that a new standard cannot be applied to some existing vocabularies, this part of ISO 25964 provides informative description alongside the recommendations, the aim of which is to enable users and system developers to interpret and implement the existing vocabularies effectively. The remainder of ISO 25964-2 deals with the principles and practicalities of establishing mappings between vocabularies.

- Abstract
- The need for Persian thesauri became apparent during the late 1960s with the advent of documentation centres in Iran. The first Persian controlled vocabulary was published by IRANDOC in 1977. Other centres worked on translations of existing thesauri, but it was soon realised that these efforts did not meet the needs of the centres. After the Islamic revolution in 1979, the foundation of new centres intensified the need for Persian thesauri, especially in the fields of history and government documents. Also, during the Iran-Iraq war, Iranian research centres produced reports in scientific and technical fields, both to support military requirements and to meet society's needs. In order to provide a comprehensive thesaurus, the Council of Scientific Research of Iran approved a project for the compilation of such a work. Nowadays, 12 Persian thesauri are available and others are being prepared, based on the literary corpus and conformity with characteristics of Iranian culture.

- Abstract
- The process of thesaurus evaluation can enhance the value of a thesaurus in terms of usability, scope, precision and recall. Structural, formative, observational and comparative evaluation techniques are explained along with specific examples of their use. These methods of evaluation can be applied in the assessment of an existing thesaurus or the construction of a new thesaurus. The history of thesauri since 1960, the development of national and international standards, and sources of evaluative literature are also discussed.

- Abstract
- International standard ISO 25964-1:2011 - Thesauri for information retrieval, includes a detailed data model for thesaurus structure. It is intended to provide a rigorous presentation of the elements and relationships which will not only clarify and standardise the varying and conflicting interpretations which exist but which can also be implemented consistently in automated systems. It makes a clear distinction between concepts and the terms which are used to label them, and includes other features that may be present in a thesaurus, such as compound equivalence, arrays and node labels, concept groups, notes and version history.

- Abstract
- This paper gives an overview of the history, development, and structure of the electronic thesauri produced and maintained by the Getty Research Institute (GRI). We describe the evolution of the Art & Architecture Thesaurus (AAT®), the Getty Thesaurus of Geographic Names (TGN®), and the Union List of Artist Names (ULAN®) as multilingual, cross-cultural knowledge organization systems (KOS); the factors that make them unique; and their potential, when expressed as Linked Open Data (LOD) to play a key role in the Semantic Web.

- Abstract
- This paper illustrates the changing role of thesauri interlinked with overall changes of modern information infrastructure services, referring to "STW Thesaurus for Economics" as a case study. It starts with an overview of the history and development of the STW and describes the far-reaching changes brought about by its publication on the Web, with regard to subject indexing, retrieval and new uses for Linked Open Data. It argues that only the most recent technological developments help thesauri to exploit their full potential which is why they more than ever have a place in current information retrieval and infrastructure.
