Call for Papers: Workshop On Linked Spatiotemporal Data 2010

Workshop On Linked Spatiotemporal Data 2010 (

In conjunction with the 6th International Conference on Geographic Information Science (GIScience 2010)

Zurich, 14-17th September, 2010; the workshop will be held on the 14th September 2010.

Workshop Description & Scope

Whilst the Web has changed with the advent of the Social Web from mostly authoritative towards increasing amounts of user generated content, it is essentially still about linked documents. These documents provide structure and context for the described data and easy their interpretation. In contrast, the upcoming Data Web is about linking data, not documents. Such data sets are not bound to a specific document but can be easily combined and used outside of the original context. With a growth rate of millions of new facts encoded as RDF-triples per month, the Linked Data cloud allows users to answer complex queries spanning multiple sources. Due to the uncoupling of data from its original creation context, semantic interoperability, identity resolution, and ontologies are central methodologies to ensure consistency and meaningful results. Space and time are fundamental ordering relations to structure such data and provide an implicit context for their interpretation. Prominent geo-related Linked Data hubs include as well as the Linked Geo Data project which provides a RDF serialization of Open Street Map. Furthermore, myriad other Linked Data sources contain location-based references. This workshop aims at introducing the GIScience audience to the Linked Data Web and discuss the relation between the upcoming Linked Data infrastructures and existing OGC services-based Spatial Data Infrastructures. The workshop results will directly contribute to the ongoing work of the NeoGeo Semantic Web Vocabularies Group, an online group focused on the construction of a set of lightweight geospatial ontologies for Linked Data. Overall, the workshop should help to better define the data, knowledge representations, reasoning methodologies, and additional tools needed to link locations seamlessly into the Web of Linked Data. Subsequently, with the advent of “Linked Locations” in Linked Data, the gap between the Semantic Web and the Geo Web will begin to narrow.

Topics of interest for the Linked Spatiotemporal Data workshop include (but are not limited to):

Application of Linked Spatiotemporal Data

  • Linked Data and the Sensor Web Enablement
  • Linked Data and mobile applications
  • Linked Data gazetteers and points of interest
  • Linked Data in the domain of cultural heritage research

Retrieving and Browsing of Linked Spatiotemporal Data

  • Mining Linked Spatiotemporal Data from existing sources
  • Spatiotemporal indexing of Linked Data
  • Harvesting Linked Data from heterogeneous sources
  • Spatial extensions to query languages such as SPARQL (e.g., GeoSPARQL)
  • Visualizing and browsing through the Linked Spatiotemporal Data cloud

Integration and Interoperation of Linked Spatiotemporal Data

  • Ontologies and vocabularies to support interoperability
  • Identity assumptions and resolution for data fusion and integration
  • The role of space and time to structure Linked Data
  • Versioning of spatio-temporal data
  • Semantic annotation and microformats
  • Adding contextual information to Linked Data

Linked Data and Volunteered Geographic Information (VGI)

  • Spatiotemporal Aspects of Data Quality, Trust, and Provenance in Linked Data
