== Abstract ==

Title: '''"A Reconciliation of Ontologies of Abstract Space: From Mereotopologies to Geometries"'''

'''Abstract:''' 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 basis 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 hierarchies 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.

[08:57] [[MichaelGruninger|Michael Grüninger]]: hi Torsten -- we cannot hear you

[08:57] [[User:TorstenHahmann|Torsten Hahmann]]: I can still hear you

[08:57] [[User:TorstenHahmann|Torsten Hahmann]]: trying to figure it out

[08:58] anonymous morphed into [[JoshLieberman|Josh Lieberman]]

[09:01] [[NancyWiegand|Nancy Wiegand]]: (ref. slide 12) What's a hierarchy, in this sense?

[09:04] [[GaryBergCross]]: Nancy, he shows some hierarchies on later slide like slide 22..

[09:05] [[MichaelGruninger|Michael Grüninger]]: @Nancy -- yes, this is not a class hierarchy, but rather a partially

ordered set of ontologies with the same set of primitive concepts and relations

[09:39] [[GaryBergCross]]: Nancy's earlier question on hierarchy might be clarified. You form

hierarchy by added restricting axioms and/or primitives.

[09:41] [[MichaelGruninger|Michael Grüninger]]: Hierarchies arise from adding different sets of axioms to theories.

All theories in the same hierarchy have the same set of primitives.

[09:09] [[ToddSchneider|Todd Schneider]]: Michael, could you post the URL that Torsten just mentioned?

I'd very much like to see the definition of 'relative dimension'.

[09:14] [[MichaelGruninger|Michael Grüninger]]: http://www.cs.toronto.edu/~torsten/qs/

[09:14] [[ToddSchneider|Todd Schneider]]: Michael, Thank you.

[09:19] [[ToddSchneider|Todd Schneider]]: Is there any representation of joining one or more spaces to form

something of larger dimension?

[09:29] [[ToddSchneider|Todd Schneider]]: Thank you Torsten. Have to go.

[09:34] [[DeborahMacPherson]]: Thanks for the presentation - need to go to a meeting.

Downloaded the slides to continue mulling over. Thanks
