  1. EnvThes Vocabulary for EnvEurope, ExpeER LTER Europe, ILTER

  2. Semantics • … andtheirusage arepartof everydays live

  3. Overview • GOAL  General decissions • Components / Links • Usage • Guidance • Whatismissing http://vocabs.lter-europe.net/Envthes3.html http://onto.nerc.ac.uk/PoolParty/index.jsp

  4. Overview • GOAL  General decissions • Components / Links • Usage • Guidance • Whatismissing

  5. GOAL of EnvThes Establish semantics Resolve semantics Semantic annotation of data Link Datum Concept Access data Manage Data Data Add meaning to data and metadata

  6. Database A Mapping A Database B Mapping B ……………… Database X Mapping X

  7. General Decissions • Follow semantic web standards – use SKOS/RDF • Be compatible with GEMET / AGROVOC /EARTh / EUROVOC, others • Be able to establish links to other knowledge bases • Be able to establish links to data

  8. SKOS/RDF Schema exactMatch closeMatch broader relatedMatch related concept resource broaderMatch narrower prefLabel narrowerMatch altLabel Definition scopeNote collection

  9. General decissions • Have a primary language • Any concept has at least one preferred label in English • Any concept should have at least one definition in English • Preferred labels and definitions in other languages are translations

  10. General decissions • LTER-Metadata system needs 1 source of knowledge representations  • Every concept has to be in this one source, even when it is imported from another source. • Concepts imported from other sources shall have a pointer back to the origin

  11. Overview • GOAL  General decissions • Components / Links • Usage • Guidance • Whatismissing

  12. EUNIS Habitats L1 – L3 US-LTER ControlledVocabulary Parameters / MethodesofEnvEurope INSPIRE spatialdataThemes Extensionsconcerning Experiments of ExpeER EnvThes NASA SWEET units Extensionsneededby ILTER DEFINITIONS CATALOGUE of LIFE (genus)

  14. Impossibility to have „one“ language for all domains But a possibilitytohave a lotofconcepts in common • Federated Thesauri • Possibilitytoshiftandmerge (iftheyhavethe same formal language • and SPARQL update)

  15. Overview • GOAL  General decissions • Components / Links • Usage • Guidance • Whatismissing

  16. General decissions • Need longterm maintenance •  need of organization providing longterm support •  CEH •  use of software used by CEH (poolParty)

  17. Interfaces of Poolparty Graphicalediting GUI LD interfac Graphicalviewing GUI Tipple store CSV (EXCEL) import poolParty TRIG / TRIX Import / export RDF/ XML/ Jason export SPARQL query & update interface

  18. Usage of EnvThes Any Dokument that supportshyperlinks Hyperlink lookup DEIMS Key words Central dB links SPARQL Endpoint Any SPARQL Client external SPARQL Endpoint

  19. Hyperlink • This isthetext, where I wanttoestablish a hyperlinkto „pollution“ togetthecorrectdefinition. The hyperlink was insertedbycopypaste http://vocabs.lter-europe.net/EnvThes3/USLterCV_436.html

  20. Link from data to EnvThes The link is established as pointer filled into the database https://secure.umweltbundesamt.at/enveurope/page/ENVEUROPE.V_REF_SUBST/TOC Semantic Annotation: Good service is needed:

  21. SPARQL QUERY over multiple sources SELECT DISTINCT ?substance ?substnam ?EnvThes_id ?term ?def WHERE {?substance a enveurope:SUBST. ?substance enveurope:SUBST_SUBST ?substnam. ?substance enveurope:ENVTHES_ID ?EnvThes_id. SERVICE <http://vocabs.lter-europe.net/PoolParty/sparql/EnvThes3> {SELECT ?EnvThes_id ?term ?def WHERE { ?EnvThes_id <http://www.w3.org/2004/02/skos/core#prefLabel> ?term. ?EnvThes_id <http://www.w3.org/2004/02/skos/core#definition> ?def}} }

  23. Usability is cucial • Ifthe autocomplete functionswere complicated, youwould not use them

  24. Overview • GOAL  General decissions • Components / Links • Usage • Guidance • Whatismissing

  25. Guidance • Bad experiences with complicated guidance (SERONTO)  simple guidance for EnvThes. • Now thinking about a simple voting system without discussion platform. • Discussion platform can be outside (WIKI)

  26. Overview • GOAL  General decissions • Components / Links • Usage • Guidance • Whatismissing

  27. What is missing • Versioning • Voting system • More relations  small ontologies • … propably a lot of properties for linguistics
