Situated Semantic Integration


Bernd Krieg-Brückner (Bremen), Angela Schwering (Münster)


This research initiative focuses on the interaction with geospatial information. The research aims at a conceptual framework for integrating representation formats—qualitative and quantitative representations—used for human and robot navigation. The research investigates human strategies to acquire and organize knowledge about spatial environments and develops intelligent computational strategies for knowledge processing. It aims at identifying and classifying situations of information access and explores new forms of human computer interaction in exploration and navigation tasks. The initiative will also investigate the integrative role of dedicated conceptual spatial frameworks, such as the Bremen Route Graph, which allows for abstracting spatial information at different levels, spatial ontologies and qualitative calculi. These forms of interaction and representation raise particular challenges and opportunities for different age groups, which will serve as use cases. Application domains include navigation systems for the elderly, interaction of ordinary users with spatial information systems and integrative representations and interaction concepts for Ambient Assisted Living (AAL) and Work (AAW) environments.


  • Qualitative spatial query language accounting for typical schematization and distortion effects in human spatial cognition
  • Using sketch drawings such as diagrams and sketch maps as data input and query to spatial information systems
  • Integration of qualitative and quantitative information, the first serving as model for human cognitive maps and the second as model for spatial information systems
  • Computational mapping approach between visual stimuli incorporating human comparison strategies such as analogies
  • Kinds of navigation activities in the geospatial context, their relation to GIS and context-based services – transition from indoors to outdoors;
  • Relationship between (navigation) activities and the environment;
  • Modeling the environment, integrating a variety of aspects: spatial and hyper-ontologies, qualitative spatial calculi;
