  • 3. 1. Current Trends and Demandsin Describing and Cataloguing Research DataIncreasing internationalization and standardization efforts: to enable and facilitate data exchange to enable and facilitate integrated retrieval across distributedinformation systemsIn the social sciences: DDI (e.g. metadata specification, controlled vocabularies) Commonly used systems for subject indexing (e.g. ELSST,CESSDA Topic Classification) …Cologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of Research Data 3
  • 4. 2. Subject Indexing of Research Data in the SocialSciences – Present Situation in Europe (1/5)CESSDA (Council of European Social Science Data Archives): Members = data archives and other organisations all acrossEurope which archive and provide social science data forsecondary use Provides access to 25,000 data collections + 1,000 datacollections every year Development and maintenance of European Language SocialScience Thesaurus (ELSST) and CESSDA Topic Classification CESSDA catalogue: allows search in data collections ofmember organisations, e.g. search by topic or search bykeywordCologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of Research Data 4
  • 5. 2. Subject Indexing of Research Data in the SocialSciences in Europe – Present Situation (2/5)Cologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of Research Data 5
  • 6. 2. Subject Indexing of Research Data in the SocialSciences in Europe – Present Situation (3/5)European Language Social Science Thesaurus (ELSST): Multilingual thesaurus for the social sciences (translated into English,Danish, Finnish, French, German, Greek, Norwegian, Spanish andSwedish) Based on the HASSET Thesaurus of UKDA Further developed by CESSDA members Planned: annual release of new version (latest version: 3/2013) Contains about 3,300 internationally applicable concepts extractedfrom HASSET Allows for local extensions of concepts Used for subject indexing of research data by CESSDA membersCologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of Research Data 6

  • 8. 2. Subject Indexing of Research Data in the Social Sciencesin Europe – Present Situation (5/5)But: No coherent indexing practice throughout the participatingarchives due to a lack of a binding indexing policy Limited representation of fine-grained national / local issues(e.g. historical, juridical, religious and political aspects, formsof national organizations, educational system, collection-specific aspects …) Retrieval limited to internationally applicable conceptsCologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of Research Data 8
  • 9. 3. Thesauri in Subject Indexing (1/3)Some general findings on thesauri: Scope and content of each thesaurus is tightlyconnected to a specific collection => scope and contentof thesauri of the same domain can differ Different levels of abstraction / specificity Different perspectives / classification aspects can lead todifferent semantic relationsCologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of ResearchData9
  • 10. 3.1 Thesauri in Subject Indexing - Internationallyusable Thesauri (2/3)Internationally usable thesaurus has to: represent concepts that exist in any language display these concepts in a hierarchical / semantic structurethat fits all languages be free of any bias be multilingualBut: Fine-grained local issues cannot be displayed Retrieval limited to internationally applicable conceptsCologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of ResearchData10
  • 11. 3.2 Thesauri in Subject Indexing - Local Thesauri (3/3)Exclusive use of a local indexing system: Represents scope of local collection Respects local aspects Allows for more precise indexing Easier to maintain Monolingual or multilingual access to local collectionBut: No access to dispersed collections that are indexed withdifferent terminological resourcesCologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of Research Data 11
  • 12. = Aggregate of local thesauri with common, internationallyapplicable core conceptsCore: Contains concepts that exist in any language Hierarchical structure fits all languages Free of bias Concepts that are already part of the local systemscan be mapped to concepts of core system Concepts that are still missing in local systemscan be added4.

  • 16. 6. Practical Aspects Need for binding indexing guidelines for core terms Data already indexed with local system remain useful User only needs to know one thesaurus Local system represents local collection Indexing with local system guarantees a more preciseindexing and respects local aspects Local systems are easier to maintainCologne, May 28 – 31 May │ Baum, Kempf │ IASSIST 2013 │ Thesaurus-Based Indexing of Research Data 16
