  2. Finding your information • In a friendly and stable environment • Clear hierarchical concepts • Connect to further information like dictionaries, databases, documents ReUse existing information • Controlled vocabulary • Uniform and Structured indexed paths • Separate Domain Knowledge and Operational Knowledge

  3. HISTORY of the MTG • 1972 IUGS/ICSTI Working groep • 1988 First edition paperback • 1995 Second edition paperback • 2000 Internet (GEIXS) (Finland)

  4. Involved Institutes • TNO-NITG, Nl • GIH, Hu • SGU, Sw • Geolba, At • China • Japan • Thailand • AGI, USA • BRGM, Fr • CNRS, Fr • BGR, De • VSEGEI, Ru • ITGE, Es • CNR, It • Geofond, Cz • GTK, Fi

  5. Present State of Art • 10.000 terms • 11 languages • Polyhierarchy • Maintenance and update in MS-Access • (Dictionary for hydrology and building materials) • Internetfacilities (incl. Cyrillic and Chinese)

  7. Our special difficulties • Many different disciplineschemistry, fysica, fossils, climate, ecomomy,hydrology, etc. • Different languagesdifferent content and meaning of terms

  8. Structure

  9. Main definitions • Thesaurus: Collection of keyterms (struct) • Ontology: Classes with structure • Knowledge base: Classes with structure and facts

  10. Modern developments • Automatic maintenance thesaurus • Ontology, RDF, XML • Multi Aspect Modelling • User input • Connection to databases, search-routines and forms (Webservices)

  11. Present Goals • Integration of existing thesauri • Decentral maintenance XML • Integration with Internet Search and Knowledge management (Semantic). • Extensions with popular terms and specialized hierarchies

  13. Not • A tool for librarians Yes • An orienting and translating tool for insiders and outsiders needing geo-information

  14. EU-PROPOSALToolsforGeo-Terminology“GEOTERM”

  15. Proposed actions • Define organisation • Define guidelines content • Restore Internet presence • Relate to other thesauri • Decentral XML-scheme per language. • Automate upgrading • Integration with other applications
