2. Electronic Field Guides Why are we interested in semantic processing What do we do now

3. Semantically based discovery 1.In what semantic categories does the provider metadata place the provider data? 2.In what semantic categories does the application place the query subject? 3.To what semantic categories does processing the ontology expand 1 and 2 and thereby inform the application which providers to query?

4. A discovery scenario What is the scientific name of the flower whose common name is Alpine Lily? Issues –What is a scientific name? –What is a flower? –What is a common name? –What is a lily? –What is an Alpine Lily? –What is an alpine lily? –Who says so?

5. Alpine Lily is Lilium parvum –CalFlora, CalAcademy –www.blackdown-lilies.org.uk –enature.com (also: Fairy Lily, Sierran Tiger Lily) –("Sierra Tiger Lily" in USDA Plants hence ITIS hence GBIF COL) Lloydia serotina – USDA Plants hence ITIS hence GBIF COL – Gresham(OR) School Steen Mountain Checklist (1995) –("Alp lily" at www.fs.fed.us)

9. Where to find prototype http://lionhead.cs.umb.edu/wsdemo –Work of Hui Dong –Select "Integrated Scientific Name Service" Generally: http://www.cs.umb.edu/efg

10. Goals of the EFG Project ID and descriptive data services on the web No assumptions about structure of characters or character states Biologist should be free of informatics professionals Participate in federations of (biodiversity, neuroscience,...) data sources

11. Query Engine Servlet Presentation Layer XSLT Engine (Xalan) Back End (OStore) http GET xml internet java query formulation POST JDOM html, specialized XML,... servlet forwarding Architecture of a UMASS Boston Electronic Field Guide

12. EFG Web Services Provide –descriptive pages Idiosyncratic but simple schema TDWG SDD Schema (alpha.01...) –Interactive and machine mediated remote or local identification tools –Metadata (Darwin Core?) –Georeferenced checklists (collaboratively with digital gazetteers (ADL DG) –recording of field observations

13. EFG Web Services Query schema –cgi prop1=value1&prop2=value2.. –regular expressions (more or less) on prop=value atoms –digIR (TDWG Access to Biological Collections Data, Initial protocol for GBIF Electronic Catalog of Names). Designed generally but implemented for specimen collections data applications.

14. EFG plans and projects Elaborate on multimedia keys Semantic discovery K12 field Guide Production Trusted access control, filtering, and integration, e.g. protect geolocations of endangered species Ontology of invasive species, especially geographically based (cf. gazetteers) Integrated common/scientific name services
