Changes to HASSET

HASSET structural review

We are undertaking a structural review of HASSET.

Since September 2017 work has focused on the reconstruction of the following hierarchies:

  • CRIME AND SECURITY
  • ENERGY
  • FOOD AND NUTRITION
  • HEALTH
  • LAW AND JUSTICE
  • POLITICS
  • SPORT
  • WELL-BEING (SOCIETY)

In each case, we tried to reduce the number of top terms (i.e. terms with no Broader Term) and orphan terms (i.e. terms with no Broader or Narrower Term), in order to make the thesaurus easier to browse. The removal of orphan terms will also make the thesaurus more SKOS-compliant.

An ongoing project is to reduce the number of polyhierarchies where possible.
