This book considers how people talk about the location of objects and places. The book reports on the latest developments in the field of spatial language and sets an agenda for future research on spatial conceptualization and communication in cognitive science, computer science, psychology, and linguistics.

This book considers how people talk about the location of objects and places. Spatial language has occupied many researchers across diverse fields, such as linguistics, psychology, GIScience, architecture, and neuroscience. However, the vast majority of work in this area has examined spatial language in monologue situations, and often in highly artificial and restricted settings. Yet there is a growing recognition in the language research community that dialogue rather than monologue should be a starting point for language understanding. Hence, the current zeitgeist in both language research and robotics/AI demands an integrated examination of spatial language in dialogue settings. The present volume provides such integration for the first time and reports on the latest developments in this important field. Written in a way that will appeal to researchers across disciplines from graduate level upwards, the book sets the agenda for future research in spatial conceptualization and communication.

People constantly talk to each other about experience or knowledge resulting from spatial perception; they describe the size, shape, orientation and position of objects using a wide range of spatial expressions. The semantic treatment of such expressions presents particular challenges for natural language processing. The meaning representation used must be capable of distinguishing between fine-grained sense differences and ambiguities grounded in our experience and perceptual structure. While there have been many different approaches to the representation and processing of spatial expressions, most computational characterisations have been restricted to particularly narrow problem domains. The chapters in the present volume reflect a commitment to the development of cognitively informed computational treatments of spatial language and spatial representation. Therefore the chapters present computational work, empirical work, or a combination of both. The book will appeal to all those interested in spatial language and spatial representation, whether they work in artificial intelligence, cognitive science, cognitive psychology or linguistics.

In conversation, people often use spatial relationships to describe their environment, e.g., "There is a desk in front of me and a doorway behind it", and to issue directives, e.g., "Go around the desk and through the doorway." In our research, we have been investigating the use of spatial relationships to establish a natural communication mechanism between people and robots, in particular, for novice users. In this paper, the work on robot spatial relationships is combined with a multi-modal robot interface developed at the Naval Research Lab. We show how linguistic spatial descriptions and other spatial information can be extracted from an evidence grid map and how this information can be used in a natural, human-robot dialog.

Using a novel model, this book investigates the psycholinguistics of dialogue, approaching language use as a social activity.

Space is presently the focus of much research and debate across disciplines, including linguistics, anthropology, psychology, and philosophy. One strong feature of this collection is to bring together theoretical and empirical contributions from these varied scientific traditions, with the collective aim of addressing fundamental questions at the forefront of the current literature: the nature of space in language, the linguistic relativity of space, the relation between spatial language and cognition. Linguistic analyses highlight the multidimensional and heterogeneous nature of space, while also showing the existence of a set of types, parameters, and principles organizing the considerable diversity of linguistic systems and accounting for mechanisms of diachronic change. Findings concerning spatial perception and cognition suggest the existence of two distinct systems governing linguistic and non-linguistic representations, that only partially overlap in some pathologies, but they also show the strong impact of language-specific factors on the course of language acquisition and cognitive development.

This book presents recent research on the role of space as a mechanism in language use and learning. Experimental psychologists, computer scientists, robotocists, linguists, and researchers in child language consider the nature and applications of this research and its implications for understanding the processes involved in language acquisition.
