  1. Controlled Vocabulary Giri Palanisamy Eda C. Melendez-Colom Corinna Gries Duane Costa John Porter

  2. Desired Result- Dream Systems • Ecological Ontologies – as an endpoint • But better goal for now set up community site for annotating data that could provide information for ontology construction • Concept mapping • Can pull out keywords and have users list synonym • Corrina has student working on text analysis, including proximity between words • Developing “related words” • Lets you make choices about how words should be used • Synonyms don’t come together in a text

  3. Desired Result/Dream System • NBII Thesaurus web service • Already have a head start • May be more productive for LTER to help make them have a better system – that LTER can use • LTER is already in NBII system and there are capabilities to link there • EIONET also has thesaurus served through NBII • Will be adding another…… • SEEK has annotation language that they use inside KEPLER….. • Also may be working annotating attributes • Used to enforce consistency

  4. Duane’s Dream • Rich and complete browse hierarchy for use in Metacat interface • Not 10 levels! Maybe 4 or 5 levels • Enhance metacat queries to extend keywords with potential related keywords • Keyword enrichment tool that would enrich keyword section of EML document • Add keywords • Tool suggests additional keywords to add

  5. Thesauri/Ontologies Data sets

  6. Issues • Different standards for online ontologies (SKOS vs TAPR etc.) • Can you convert? NBII is looking at…. • Would like to have option of matching thesarus keywords in EML documents • Thesaurus is not explicitly a hierarchy….

  7. Discussion on Automation • NBII has worked on some tools… • Could make enrichment of EML documents by keywords a USER function • Learn from users • Now have audited metacat searches so have a database with 3 months worth of queries

  8. Demo of Systems • CAP Semantic Research • http://149.169.202.24:8080/ecologyes • Development server • NBII Thesaurus Site • http://nbii.ornl.gov/thesaurus

  9. Ideas • Publication on LTER vocabulary and relationship to NBII Thesaurus and other resources • Send list to NBII, they will return report on hits • How can LTER contribute? • Corrina’s system could be used to help propose new information • Can add information to NBII Thesaurus….

  10. Challenges • Evaluating lists/thesauri/ontologies that would benefit LTER • Linking existing EML documents with context from a list/thesaurus/ontology • Developing a dataset hierarchy from the interaction of LTER data catalog with list/thesaurus/ontology

  11. Steps • Need training on how to use web services for NBII access • Duane, Corinna, Inigo • Send list of terms for checking in NBII • Need to finalize multi-word keyword list • Revise Token/Word list – to update • Human input? • Further Discussion – Workshop at NCEAS? • Relationships between LTER, SEEK and NBII • Editing, sharing, CAP work • How to harvest user input to help “educate” system • CAP Student can participate

  12. Next Steps • Corinna will check with SEEK on opportunities there • Giri will check with Mike Frame on NBII buy-in • VTC Last Week of August 2007?? • Develop plans for future activities • Workshops • Visits • Activities
