Abstract

Natural language allows for efficient communication of elaborate descriptions of movement without requiring precise specification of the motion. Interpreting Motion is the first book to analyze the semantics of motion expressions in terms of the formalisms of qualitative spatial reasoning, mapping motion descriptions in language to trajectories of moving entities based on qualitative spatio-temporal relationships. The book provides an extensive discussion of prior research on spatial prepositions and motion verbs, and devotes chapters to the compositional semantics of motion sentences, the formal representations needed for computers to reason qualitatively about time, space, and motion, and the methodology for annotating corpora with linguistic information in order to train computer programs to reproduce the annotation. The applications they illustrate include route navigation, the mapping of travel narratives, question-answering, image and video tagging, and graphical rendering of scenes from textual descriptions. The book is written accessibly for a broad scientific audience of linguists, cognitive scientists, computer scientists, and those working in fields such as artificial intelligence and geographic information systems.
