6 Conclusions
</SectionTitle>
    <Paragraph position="0"> We addressed the issue of how we can provide a context-dependent interpretation of spatial expressions that identify objects based on proximity in a visual scene. We discussed available psycholinguistic data to substantiate the usefulness of having such a model for interpreting and generating fluent situated dialogue between a human and a robot, and that we need a context-dependent representation of what is (situationally) appropriate to consider proximal to a landmark.</Paragraph>
    <Paragraph position="1"> Context-dependence thereby involves salience of landmarks as well as inhibition effects between landmarks. We presented a model in which we can address these issues, and we exemplified how logical forms representing the meaning of spatial proximity expressions can be grounded in this model. We tested and verified the model using a psycholinguistic experiment. Future work will examine whether the model can be used to describe the semantics of nouns (such as corner) that express vague spatial extent, and how the model relates to the functional aspects of spatial reasoning.</Paragraph>
