Proximity in context
John D. Kelleher, Geert-Jan M. Kruijff, Fintan Costello · 2006
The paper presents a new model for context dependent interpretation of linguistic expressions about spatial proximity between objects in a natural scene. The paper discusses novel psycholinguistic experimental data that tests and verifies the model. The model has been implemented, and enables 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.
