Competence in spatial language modeling is a cardinal issue in disciplines including Cognitive Psychology, Computational Linguistics, and Computer Science. Within Cognitive Psychology, the relation of spatial language to models of spatial representation and reasoning is considered essential to the development of more complete models of psycholinguistic and cognitive linguistic theories [1]. Meanwhile, within Computer Science and Computational Linguistics and Engineering, the development of a wide class of so-called situated systems such as robotics, virtual characters, and Geographic Information Systems is heavily dependent on the existence of adequate models of spatial language use [2].
