I1-[OntoSpace] Ontologies for Spatial Communication John Bateman, Kerstin Fischer, Reinhard Moratz Scott Farrar, Thora Tenbrink
2
2 I1-[OntoSpace] user Rolland Pioneer Provision of natural dialogic interaction concerning user tasks in a spatial context presentation of spatial information communication of spatially-situated actions Focusing on RE-USABILITY of components and EXTENSIBILITY of approach producing NON-TASK SPECIFIC solutions Motivation
3
3 I1-[OntoSpace] Difficulties different perceptual systems of human and robot: necessity of mediation discourse situation influences linguistic choices determining factors as yet unknown
4
4 I1-[OntoSpace] Two problem areas for investigation Complexity of negotiating spatial relations Variability of reference systems Discoursal negotiation processes Situational factors Unfamiliarity of interaction situation Communication with an artificial interlocutor Choice of linguistic expressions No knowledge about robot‘s functionalities
5
5 I1-[OntoSpace] Reference systems Intrinsic: Localisation of object by reference to the intrinsic properties of another entity, e.g. speaker‘s front: “The ball is in front of me” Relative: Presence of relatum required: “The ball is in front of the table” Group-based reference if one of several similar objects is referred to: “The leftmost ball” Absolute: the earth‘s cardinal directions (north, south)
6
6 I1-[OntoSpace] Perspectives Speaker-centered: Intrinsic: “The ball is in front of me” Relative: “From my point of view, the ball is to the right of the table” Absolute: “to the north of me” Listener-centered: Intrinsic: “The ball is in front of you” Relative: “From your point of view, the ball is to the right of the table” Absolute: “to the north of you”

7 I1-[OntoSpace] Our approach Elicitation of data in experimental settings analysis of linguistic choices in relation to situational parameters (spatial settings and tasks; robot appearance and behavior) Integration in a single functioning system modeling of dialogue mechanisms achieving flexibility of interpretation by modularity Ontology mapping Flexibility of mapping mechanisms required: the discourse model informs how the domain model concept is to be subordinated in a given context

16 I1-[OntoSpace] I1: Targetted results development of a comprehensive spatial ontology development of linguistic ontology for handling linguistic tasks representation of all ontologies in OWL and CASL specifications specification of principles and methods for inter-ontology mappings specification of discourse-history and robot- conceptualisation conditionalistions of the mappings
