10 minute overview!

• Explore what we mean by shared terminology
  services
• Locate terminology services within JISC
  Information Environment (IE)

3
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

6
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 .

Student enters search terms to Portal
interface Portal queries HILT for matching Dewey
notation HILT interacts with IE Service Registry
to locate relevant collections Details of
collections returned to Portal Portal sends query
to appropriate collections

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?

11
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

12
Where to position HILT?

• Somewhere along continuum from research and
  development project to operational service
• Recommendations in delegate pack
