A Unified Semantics Space Model,onships. This structure not only provides multiple graphs at different abstraction levels, but it also collapses the whole map into smaller local graphs. This mechanism is beneficial in reducing the complexity of creating and maintaining a map and improving the efficiency of path finding algorithms.

Inferring Position Knowledge from Location Predicates, external spatial data are difficult to incorporate into existing mechanisms. In this paper, we introduce a new approach to deal with different types of position data which typically appear in context- or location-aware application scenarios.

Bootstrapping a Location Service Through Geocoded Postal Addresses,s (wardriving) with the accuracy of the geocoded postal address. The results show similar accuracy for geocoding in comparison to typical wardriving studies, with significantly reduced effort if postal addresses of access point positions are known.

Deployment, Calibration, and Measurement Factors for Position Errors in 802.11-Based Indoor Positiotioning system by selecting advantageous values for these parameters. For our study, we utilize a test environment with a size of about 312 square meters that is covered with 612 reference points arranged in an equally spaced grid.
