Tue June 19^th 2012 there will be   Joint SOCoP-OOR Presentation on Spatial Ontology Presentation by Torsten Hahmann.   

The talk is entitled - A Reconciliation of Ontologies of Abstract Space: From Mereotopologies to Geometries.

Torsten has provided the following abstract based on his PhD research at the University of Toronoto:

This work focuses on bridging the gap between very weak ontologies of abstract space (in particular those relying only on topological and mereological relations) and more traditional geometries.

As a start we developed a general mereotopology based on spatial containment and relative dimension that is dimension-independent, i.e., in which points, curves, areas, etc. can coexist.  By successively adding additional primitive relations (boundary containment, betweenness, and convex hulls) and ontological assumptions we construct a hierarchy(ies) of spatial ontologies.  We locate existing spatial ontologies ranging from mereotopologies to various geometries in these hierarchies, thereby establishing the relationships amongst them.  As more and more ontologies of abstract space are included, we refine our understanding of their shared and differing ontological assumptions as well as their necessary primitive relations.
All theories are axiomatized in Common Logic, formally verified with the help of automated tools, and will be made available as part of COLORE. The hierarchies can be used as basis for the integration of diverse spatial ontologies from geography, engineering, architecture, and other fields.

This session will be Chaied Gary Berg-Cross (SOCoP) & MichaelGruninger (U of Toronto).
