High-Level Thesaurus
Welcome to the website of the High-Level Thesaurus Project (HILT). The HILT project, which is now in phase IV, aims to research, investigate and develop pilot solutions for problems pertaining to cross-searching multi-subject scheme information environments.
About HILT phase IV...
Problems relating to disparate terminology use have been an impediment to information retrieval for many years, but the growth of the Web, associated heterogeneous digital repositories, and the need for distributed cross-searching within multi-scheme information environments has recently drawn the issue into sharp focus, particularly within the JISC Information Environment.
'HILT phase IV: Transition to Service Testbed and Future Requirements Study' aims to research, investigate and develop pilot solutions for problems pertaining to cross-searching multi-subject scheme information environments, as well as providing a variety of other terminological searching aids.
HILT phase IV will build on the work of phase III by moving HILT to a transition to service phase. This will allow an initial entry-level service to be built, tested for user requirements and retrieval effectiveness, refined in line with the findings, and extended to permit the use of a range of distributed terminology services for interoperability. It will also allow an examination of the level of need and interest amongst JISC services in respect of an operational service and, if appropriate, a scoping of the costs and requirements of a future operational phase of the service.
HILT phase IV will also conduct a parallel programme of research into selected topics germane to terminology services, as well research into the costs and requirements of an initial entry-level operational service and any future extension of this.
