摘要

Text documents frequently contain descriptions of different kinds of movements byindividual persons, groups, animals, vehicles, or other moving objects. Comprehend-ing and modeling the semantics of movement is an area of interest for geographicinformation science. In this article, we show how text documents that containmovement verbs can be analyzed for deriving representations of movement ordynamic paths. A conceptual framework is presented that provides the foundationsnecessary for deriving dynamic paths automatically from natural language descrip-tions and representing these dynamic paths in an information system, such as ageographic information system. In this research, a linguistic analysis of dynamicpaths is presented and linked to a spatiotemporal representation of paths. We showhow movement descriptions in text can be mapped to a set of elemental componentsincluding source, destination, route, direction, distance, start time, end time, andduration. Together, this set of path components captures the spatiotemporal char-acteristics of the path of a moving object as described using natural language. Asystematic examination of these components builds a foundation for understandingmore complex scenarios involving discourse (composed of consecutive sentences).Additional aspects reflecting important semantics about the movement characteris-tics of objects and discussed here are the shape of the path and granularity ofmodeling.
