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)
• 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 are
expanding 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)

Purpose of the SOCoP INTEROP Grant
• Apply and develop semantic technologies for the
Geospatial domain
• Share ontologies to promote data interoperability

• 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

Ontology Repository and
GeoSPARQL
• Open Ontology Repository (OOR)
• Adding spatial functions to the RDF
SPARQL query language (GeoSPARQL)
SSO 2011
Sponsored Workshops
• SOCoP Workshop on Friday, Dec. 2,
in the D.C. area (USGS in Reston,
VA), no registration fee

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

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
