N2 - Social Situations (SSs) are social context models indicating n-ary social interaction on small spatio-temporal scales detected by means of Social Signal Processing (SSP). We discuss the problem of how to combine evidence from several sensorsources for the benefit of algorithmic assessment of SS in a distributed agent-based Social Networking scenario. We propose a solution based on Subjective Logic (SL) that mediates between exchanging & processing of (a) raw low level sensor data, of (b) intermediate results of'sub- symbolic'probabilistic models typically used for SSP, and of (c) the final'symbolic'SS models. We evaluate key aspects of the approach on the basis of a social experiment, combining audio-based and geometry-of-interactionbased methods for SS detection.
