Semantic Web Journal
Special Issue on Linked Spatiotemporal Data and Geo-Ontologies


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 Geonames.org 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
special issue is an open-call follow up to the Linked Spatiotemporal
Data 2010 workshop held in conjunction with the 6th International
Conference on Geographic Information Science GIScience 2010. The issue
aims at defining 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.

List of Relevant Topics

Submissions
The special issue on Linked Spatiotemporal Data and Geo-Ontologies calls
for original high-quality research on any of the above mentioned topics.
Extended versions of manuscripts published in conferences and workshops
are welcome as long as the previous publications are clearly
acknowledged and the new submission introduces substantial revisions and
updates. Authors are requested to follow the author guidelines, submit
online via mstracker, and include the name of the call within the
submission letter. While there is no official page limit, we request
manuscripts between 14-22 pages in length. All manuscripts will be
reviewed based on the SWJ open and transparent review policy and will be
made available during online the review process.
