SOCoP Dec Geospatial Semantics Nancy Wiegand University of Wisconsin - Madison

Nancy Wiegand SOCoP Dec Spatial Ontology Community of Practice (SOCoP) SOCoP was developed because of the: –Recognition of the semantic interoperability component of geospatial data –Realization of the potential of ontologies and formal representations to help solve semantic heterogeneity in geospatial data SOCoP officially began in Oct after a June meeting at the National Science Foundation

SOCoP ( SOCoP Dec Membership in SOCoP is open to anyone Conference calls are held every month, currently on the 3 rd Wednesday at 11:00 Eastern time Through an NSF INTEROP grant, we are expanding SOCoP to create a larger Network We invite those here to participate.

SOCoP Dec INTEROP – Spatial Ontology Community of Practice: an Interdisciplinary Network to Support Geospatial Data Sharing, Integration, and Interoperability NSF Program: Community-based Data Interoperability Networks (INTEROP)

SOCoP Dec Purpose of the SOCoP INTEROP Grant Apply and develop semantic technologies for the Geospatial domain Share ontologies to promote data interoperability Submitted by 8 members of SOCoP : – Gary Berg-Cross - Knowledge Strategies, Inc. – Nancy Wiegand - University of Wisconsin-Madison, – James Wilson - James Madison University – Mike Dean and Dave Kolas – Raytheon BBN Technologies – Naijun Zhou - University of Maryland College Park – Peter Yim - CIM Engineering, Inc. – John Moeller - JJMoeller and Associates

INTEROP Tasks - Overview Web presence – Wiki ( Workshops/meetings, in-person/virtual Prototypes or demos Create a geospatial ontology repository Educational component Basic research in geospatial data interoperability SOCoP Dec. 2011

Web-Based Collaboration Methods CIM3 CWE (Collaborative Work Environment, Peter Yim) –Wiki, can put links to slides and other pages – We have started to create pages here, including educational material

Nancy Wiegand Original Semantic Web Vision: Mark up Web documents and data to be machine-processable This requires: Additional Knowledge Representation (HTML  XML, RDF, OWL) Ontologies Reasoners Spatial representation Spatial ontologies Spatial reasoners, Spatial rules, Spatial operators SOCoP Dec. 2011

A Vision for Spatial Semantics and Ontologies Improve search for geospatial data and services –Ontologies for semantics and background knowledge Improve querying in geospatial data –Semantic interoperability Combining information, Discovering new information Role of ontologies in different geo-architectures –e.g., demos, decision-support systems, cyberinfrastructures Geospatial data in the Linked Open Data cloud SOCoP Dec Nancy Wiegand

Search - Geospatial One-Stop 600 results ‘River’ in ‘Dane County’

SOCoP Dec Ordnance Survey Linked Sensor Data Linked GeoData Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. Linked Open Data Geospatial Data in the Cloud

Putting Wisconsin data into RDF and (maybe) eventually into the LOD cloud D2RMap (.dbf -> RDF) Sesame (store)

Possible Workshop Design to incorporate semantics/ontologies into computer architectures –Spatial Data Infrastructures, portals, cyberinfrastructures, information systems Where/how do ontologies fit in? –How are they found? Remote ontologies? What component knows which ontology to use? Use of DBMS? Ontology driver for entire system? Nancy Wiegand SOCoP Dec. 2011

Broaden the INTEROP Network We invite those here to participate. e.g., use cases SOCoP Dec. 2011

Thank you! Nancy Wiegand SOCoP Dec. 2011
