TRANSCRIPT
10 minute overview!
• Explore what we mean by shared terminology services
• Locate terminology services within JISC Information Environment (IE)
Shared services…?
• Delivering services in automated way
• As m2m services to other software components…
• …rather than direct to user via browser
• Typically by means of Web Services technologies

HILT as shared service
• HILT can be considered as a number of services– Term mapping– Disambiguation– Collection finder
• HILT is just one of a range of potential terminology services – Domain specific thesauri – Semantic expansion
Building scenarios
• To understand how application might use terminology services
• To identify interaction between different shared services
• To explore integrating terminology services with other DL services
• N.B. Need to be validated ….

What is needed ?
• Structured representation of– Terminologies (thesauri, classification
schemes, ontologies, KOS)– Query (common queries)– Exchange format (returned records)
• Common standards!– How many and which ones?
Current activity• Revision of international standards for
thesauri structure
• Experimental demonstrators– Vocabulary mark up (MARC21, VDEX, TIF) – Protocols (Zthes, ADL, OAI-PMH)– Proposals emerging from research
• Possibilities to interface with proprietary products using SOAP and XML
Where to position HILT?
• Somewhere along continuum from ‘research and development project’ to ‘operational service’
• Recommendations in delegate pack…
