Decomposing Path Shapes: About an Interplay of Manner of Motion and 'The Path'

Abstract

In this paper we will develop a formal conceptual model of how the path in a motion situation interacts with the semantic analysis of so called ‘motion shape verbs’ like ‘wackeln’ (‘wobble’), a subclass of the so called ‘manner of motion verbs’. Central to this model will be the distinction between two concepts of motion: translational motion and nontranslational motion, which has no inherent translational component but puts emphasis on describing specific Motion Shape Patterns. We will define and algorithmically describe a theory of Path Shape Decomposition that aims at algorithmically deriving the translational vs. nontranslational distinction from the shape of the path. To account for object internal motion, we additionally introduce Bounding Box encapsulation, which yields a topological division of inner and outer movement. Finally we demonstrate how the outcome of such a technical decomposition can be used in modelling a Path Superimposition scenario like ‘Peter wackelt u¨ ber die Straße’.
