TAILIEUCHUNG - Báo cáo khoa học: "A COMPUTATIONAL VIEW OF THE COGNITIVE SEMANTICS OF SPATIAL PREPOSITIONS*"

This paper outlines the linguistic semantic commitments underlying an application which automatically constructs depictions of verbal spatial descriptions. Our approach draws on the ideational view of linguistic semantics developed by Ronald Langacker in his theory of Cognitive Grammar, and the conceptual representation of physical objects from the two-level semantics of Bierwisch and Lang. In particular the dimensions of the process of conventwnal imagery are used as a metric for the design of our own conceptual representation. . | A COMPUTATIONAL VIEW OF THE COGNITIVE SEMANTICS OF SPATIAL PREPOSITIONS Patrick Olivier Centre for Intelligent Systems University of Wales Aberystwyth Dyi ed SY23 3DB UK Internet plo@ Abstract This paper outlines the linguistic semantic commitments underlying an application which automatically constructs depictions of verbal spatial descriptions. Our approach draws on the ideational view of linguistic semantics developed by Ronald Langacker in his theory of Cognitive Grammar and the conceptual representation of physical objects from the two-level semantics of Bierwisch and Lang. In particular the dimensions of the process of conventional imagery are used as a metric for the design of our own conceptual representation. INTRODUCTION An increased interest in the semantics of spatial language has accompanied the recent rise in popularity of cognitive linguistics see Rudzka-Ostynl988 yet computational approaches are thin on the ground. This can in part be accounted for by the rather descriptive and unformalized nature of the theories developed but is more likely due to the adoption of an ideational view of linguistic meaning which it seems is an anathema to computational linguists. In this paper we take a serious if informal look at Ronald Langacker s theory of Cognitive Grammar Langacker1987 Langacker1988a Langacker 1988b more specifically its commitment to conceptualization and the use of conventional imagery. The first section of this paper introduces the semantics of projective prepositions eg. in front of behind left of right of illustrating that these seemingly simple predicates are supris-ingly complex and ambiguous. In the light of this discovery the following sections consider Langacker s view of linguistic meaning and the design of a conceptual representation for spatial prepositions motivated by the consideration of the various This research was kindly funded by the Matsushita Electric Industrial Company Limited.
