INIS Thesaurus: new terms and new interface

A new version of the INIS Interactive Multilingual Thesaurus has been developed and is available at:

This new Thesaurus version continues the commitment of the Nuclear Information Section (NIS) to offer users an enhanced experience and greater support for new technologies and devices.

Simplified user interface

The user interface has been simplified and is now consistent with that of the INIS Collection Search. It is especially well formatted for use with tablet computers. A user simply chooses a language of input, and begins typing in the text box provided. A list of terms matching the user input appears. The user may either select from the list, or continue typing. When a term is selected, the date the term was added to the INIS Thesaurus, a definition (if one exists), and related terms appears. Each of the related terms may then be selected, to provide that term’s wordblock.

Multilingual support

Descriptors may be entered in Chinese, English, French, German, Japanese, Russian, and Spanish. After selecting a term, translations are also available in each of these languages.

New Terms

The INIS Thesaurus is a controlled terminological knowledge base that has been developed over the years through the contribution of INIS Member States in all areas of peaceful applications of nuclear science and technology, which is also the subject scope of the INIS Collection. The thesaurus is primarily used for subject indexing of input into the INIS system and for retrieval of information from the database. Thanks to the vital support of the INIS Member States, the thesaurus has been translated into eight languages (i.e all IAEA official languages plus German and Japanese) and is available online to assist our global users as a tool for retrieval and for general reference services. It is a dynamic information resource that is continually updated to cater to new developments of terminologies in nuclear science and technology. As of the end of October 2013, the INIS Thesaurus contains a total of 30,746 terms. Some of the recent additions to the thesaurus include terms from diverse subjects such as: FUKUSHIMA DAIICHI NUCLEAR POWER STATION, LEPTOQUARKS, RADIOEMBOLIZATION, SMART GRIDS and FLEROVIUM.
