I5-[DiaSpace] is a fusion of the I1-[OntoSpace] and I3-[SharC] projects. Both projects were originally conducted idependently. Whereas I1 was (and still is) primarily dedicated to spatial and linguistic ontologies, I3 was working on the development of a dialogue system.
Just like I1 and I3, I5-[DiaSpace] is a part of the interdisciplinary Transregional Collaborative Research Center on Spatial Cognition at the University of Bremen in Bremen, Germany. The Center was established by the Deutsche Forschungsgemeinschaft (DFG) on 01 January 2003 at the Universities Bremen and Freiburg and is the 8th Transregional Special Research Project (SFB/TR8) funded by the DFG.
