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. 2006 after a June meeting at the National Science Foundation
SOCoP (www.socop.org)
SSO 2011
• Membership in SOCoP is open to anyone
• Conference calls are held every month, currently on the 3rd Wednesday at 11:00 Eastern time
•Through an NSF INTEROP grant, we areexpanding SOCoP to create a larger Network
•We invite those here to participate.

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)
SSO 2011
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
• Educational component
• Create a geospatial ontology repository
• Basic research in geospatial data interoperability

Web-Based Collaboration Methods
• CIM3 CWE (Collaborative Work Environment, Peter Yim)– Wiki, can put links to slides and
other pages– www.socop.org
• We have started to create pages here, including educational material
http://ontolog.cim3.net/cgi-bin/wiki.pl?NsfInterop_Grant
Ontology Repository and GeoSPARQL
• Open Ontology Repository (OOR)
• Adding spatial functions to the RDF SPARQL query language (GeoSPARQL)

Sponsored Workshops
• SOCoP Workshop on Friday, Dec. 2, in the D.C. area (USGS in Reston, VA), no registration fee
• Just past--Terra Cognita Workshop at ISWC 2011
Broaden the Network
We invite those here to participate.

Possible Discussion Topics
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
Search - Geospatial One-Stop

Vision
• 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
• Geospatial data in the Linked Open Data cloud

Issues with Ontologies
• Who creates the ontologies?– How to get the right people together– Find use cases, Is the ontology right for the use case?– Get domain scientists or practitioners to focus on the
problem
• Where to find ontologies once created– Repositories
• Technology/architecture to use ontologies
