The UK's largest digital collection of social sciences and population research data

Controlled vocabularies

ELSST is a broad-based, multilingual thesaurus for the social sciences, owned and published by the Consortium of European Social Science Data Archives (CESSDA).

It was originally based on the Humanities and Social Science Electronic Thesaurus (HASSET) which was owned and developed by the UK Data Archive from the 1970s to 2021.

ELSST is currently available in 15 languages: Czech, Dutch, English, Finnish, French, German, Greek, Hungarian, Icelandic, Lithuanian, Norwegian, Romanian, Slovenian, Spanish, and Swedish, and contains over 3,4 00 concepts. We use it to index our data collections at study, question and variable level. The thesaurus allows retrieval of data and related documentation using hierarchies of keywords.

It is also used for data discovery within CESSDA, including the CESSDA Data Catalogue (CDC) and thus facilitates access to data resources across Europe, independent of domain, resource, language or vocabulary. The UK Data Archive co-ordinates ELSST on behalf of CESSDA and works with other European data archives to develop its content and facilitate translation.

Some key facts about ELSST:

  • Covers the core social science disciplines: politics, sociology, economics, education, law, crime, demography, health, employment, information and communication technology and environmental science.
  • Follows ISO 25964: Thesauri and interoperability with other vocabularies as far as possible.
  • Is available in the Linked Open Data format, SKOS.
