(Perceptual) grounding as interaction

Simon Dobnik, Amelie Åstbom

We examine how changing perceptual contexts affects grounding of words (spatial descriptions) in perceptual features and argue that grounding is interactive. We discuss two effects of perceptual context. Grounding of spatial descriptions may be affected by the richness of the perceptual context which allows us to build more complex representations of scenes. Secondly, perceptual grounding is dependent on the task (and associated attention) which affects the preference of features. The second property connects perceptual grounding closely to linguistic grounding in dialogue. We also argue that dynamic perceptual grounding has implications for the words-as-classifiers approach to semantics.
