A location and action-based model for route descriptions

摘要: Representing human spatial knowledge has long been a challenging research area. The objective of this paper is to model route description navigation where verbal descriptions constitute the inputs modeling approach. We introduce structural and logical that applies graph principles representation descriptions. main assumption approach can be modeled as path made locations actions, both being labeled by landmarks entities. This supported previous studies an experimentation in natural environment confirm role entities derives formal facilitates comprehension analysis its properties. It graphic language, illustrated preliminary prototype implementation applied environments.
