Grammar and Semantics OntoSpace/DiaSpace • Describing how spatial language is actually used according to • the literature • our controlled experiments • Formulating an abstract linguistic semantics for spatial expressions in general • Using principles from ontological engineering and heterogeneity for guidance

Defining spatial commitments OntoSpace/DiaSpace • linguistic semantics • (all and) only the commitments licensed by the linguistic constructions employed spatial linguistic semantics

Definition and use of the linguistic ontology OntoSpace/DiaSpace • Linked to lexicogrammar and syntax by firm constraints on possible constructions • Linked to more detailed semantics via axiomatization • The categories of the ontology provide a ‘public’ class-subclass-role organization that hides many details of semantics • The semantics of natural language expressions is then envisaged as ‘composition’ of the various spatial theories they invoke.

Issues for a spatial natural language semantics • Needs to connect classes of expressions with classes of axiomatised theories whose domains are abstract and not yet related to ‘real’ space (cf. Eschenbach, Zwarts, ...) • Relation of linguistic evidence to formal properties? (cf. Mossakowski/Wölfl) • Relations of abstract linguistic spatial theories to non-linguistic spatial theories (models of space) – heterogeneous ontologies? (cf. Kutz/Hois) • Relations of abstract linguistic spatial theories to embodiment/simulations?
