Abstract

The paper presents a new model for context- dependent interpretation of linguistic expressions about spatial proximity between objects in a nat- ural scene. The paper discusses novel psycholin- guistic experimental data that tests and verifies the model. The model has been implemented, and en- ables a conversational robot to identify objects in a scene through topological spatial relations (e.g. 'X near Y'). The model can help motivate the choice between topological and projective prepositions.
