- Content
- ""A thesaurus is a terminological control device used in translating from the natural language of documents, indexers or users into a more constrained `system language' (document language, information language)". It is also "a controlled and dynamic vocabulary of semantically and generically related terms which covers a specific domain of knowledge". The Joint INIS/EDTE Thesaurus fits this definition adopted by UNESCO.' The domain of knowledge covered by the Joint INIS/ETDE Thesaurus includes physics (in particular, plasma physics, atomic and molecular physics, and especially nuclear and high-energy physics), chemistry, materials science, earth sciences, radiation biology, radioisotope effects and kinetics, applied life sciences, radiology and nuclear medicine, isotope and radiation source technology, radiation protection, radiation applications, engineering, instrumentation, fossil fuels, synthetic fuels, renewable energy sources, advanced energy systems, fission and fusion reactor technology, safeguards and inspection, waste management, environmental aspects of the production and consumption of energy from nuclear and non-nuclear sources, energy efficiency and energy conservation, economics and sociology of energy production and use, energy policy, and nuclear law. The terms in the Joint Thesaurus are listed alphabetically. For each alphabetical entry, a "word block", containing the terms associated with this particular entry, is displayed. In the word block, terms that have a hierarchical relationship to the entry are identified by the symbols BT for Broader Term, and NT for Narrower Term; a term with an affinitive relationship is identified by RT, for Related Term; terms with a preferential relationship are identified by USE or SEE, and OF for Used For, and SF for Seen For. In case of multiple USE relationships for a forbidden term, all listed descriptors should be used to index or search a given concept. In case of multiple SEE relationships, one or more of the listed descriptors should be considered for indexing or searching this concept."

- The latest version of the Joint INIS/ETDEThesaurus has been published, English on paper, Multilingual (Arabic-Chinese-English-French-GermanRussian-Spanish) on CD: Joint Thesaurus Part I (A-L) and Part II (M-Z) ETDE/INIS Joint Reference Series No. 1 (Rev. 2) The ETDE/INIS Joint Thesaurus (Rev. 2) contains the controlled terminology for indexing all information within the subject scope of INIS and the Energy Technology Data Exchange (ETDE). The terminology is used in subject descriptions for input to, or retrieval of, information in these systems. The Joint Thesaurus is the result of continued editing in parallel to the processing of the INIS and ETDE databases. With updates to September 2006 Rev. 2 includes 21147 valid descriptors and 9114 forbidden terms. IAEA-ETDE/INIS-1 (Rev. 2), 1221 p., 2007, ISBN 92-0-102207-7, English. 120.00 Euro.
