Tutorials at GeoS 2009

Third International Conference on Geospatial Semantics (GeoS 2009)

‘OWL 2 Rules’

The revision 2 of the Web Ontology Language OWL is much richer than its predecessor OWL 1.0 with respect to modelling with rules. In particular, a significant portion of OWL 2 DL is already expressible using rules (called SROIQ Rules). The tractable profile OWL 2 EL can be extended by rules - within OWL 2 DL - while retaining tractability. Further rules lying outside OWL 2 DL, in particular a generalisation of DL-safe Datalog rules, can further be added while still retaining tractability, resulting in a language called ELP, which covers all three tractable profiles of OWL 2. ELP in turn can be extended by local closed-world reasoning such that data complexity still remains polynomial.

This tutorial introduces OWL 2 and the abovementioned rules fragments and extensions in detail. It is aimed for the theoretician as well as the ontology engineer who would like to learn about the intimate relationship between OWL 2 and rules.

“Building a Web of Sensors”

The vision of the Sensor Web is to make all kinds of sensors discoverable, accessible and taskable over the internet. To achieve this vision, the Sensor Web Enablement (SWE) initiative of the Open Geospatial Consortium (OGC) is defining standards for the Sensor Web. After introducing the different building blocks of the Sensor Web, the application of these in different scenarios will be demonstrated. Furthermore, the 52°North SWE suite will be presented as an Open Source implementation of the SWE standards. Finally, the first steps and necessary future work towards a Semantic Sensor Web will be explained.

Third International Conference on Geospatial Semantics (GeoS 2009)


Third International Conference on Geospatial Semantics (GeoS 2009)


Purpose and Scope

Geospatial semantics is an emerging research theme in the domain of geographic information systems and spatial databases. The previous editions of the conference – GeoS 2005 and GeoS 2007 in late November (Mexico City, Mexico) www.geosco.org were highly successful. We have received about 100 submissions, from which 30 regular and 8 short articles have been published in Volume 3799 and Volume 4853 of the Lecture Notes in Computer Science respectively. People from 28 countries and 5 continents have attended the GeoS conferences.

The third edition GeoS 2009 www.geosco.org aims at providing a forum for the exchange of state-of-the-art research results in the areas of modeling and processing of geospatial semantics. Geospatial semantics play an important role for next-generation spatial databases and geographic information systems, as well as specialized geospatial web services. This conference traditionally brings together researchers whose expertise will address issues such as:

* Theories for geospatial semantic information
* Formal representations of geospatial data
* Models and languages for geoontologies
* Alignment and integration of geoontologies
* Integration of semantics into spatial query processing
* Spatial information retrieval
* Ontology-driven GIS
* Geospatial Semantic Web
* Multicultural aspects of spatial knowledge
* Cognitive aspects of geospatial semantics
* Measuring semantic similarity between spatial datasets
* Representing context for geospatial semantic information
* Semantic Sensor Web
* Ontology-based visualization of geospatial data
* Conceptual models of dynamic geospatial environments
* Personalization of geospatial semantic services

Paper Submissions

Authors are invited to submit full papers of approx. 18 single-spaced pages, in English, formatted in Springer’s Lecture Notes in Computer Science style (www.springer.de/comp/lncs/authors.html). Papers, formatted in PDF, must be submitted through the conference web site (www.geosco.org). At least three members of the Program Committee will evaluate each paper based on scientific significance, relevance to the conference, novelty, relation to previously published literature, and clarity of presentation. The GeoS 2009 proceedings will be published as a volume in Springer’s LNCS series.


* Pascal Hitzler: State of the Art and Vision for the Semantic Web

* 2nd Keynote to be announced


* Building a Web of Sensors; 52°North (Arne Bröring and colleagues)

* OWL 2 Rules; Pascal Hitzler, Markus Krötzsch and Sebastian Rudolph


GeoS 2009 will be held at the Centro de Investigacion en Computacion (CIC) in Mexico City (www.cic.ipn.mx). The conference site has a spectacular view of the Popocatepetl volcano, which will be snow-covered at the beginning of December. Early December is the best time of the year for traveling to Mexico City with typically clear weather, moderate temperatures, and a deep blue sky.
