Spatial Language

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.

This book presents groundbreaking robotic experiments on how and why spatial language evolves. It provides detailed explanations of the origins of spatial conceptualization strategies, spatial categories, landmark systems and spatial grammar by tracing the interplay of environmental conditions, communicative and cognitive pressures. The experiments discussed in this book go far beyond previous approaches in grounded language evolution. For the first time, agents can evolve not only particular lexical systems but also evolve complex conceptualization strategies underlying the emergence of category systems and compositional semantics. Moreover, many issues in cognitive science, ranging from perception and conceptualization to language processing, had to be dealt with to instantiate these experiments, so that this book contributes not only to the study of language evolution but to the investigation of the cognitive bases of spatial language as well.

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.

Despite a growing interest for space in language, most research has focused on spatial markers specifying the static or dynamic relationships among entities (verbs, prepositions, postpositions, case markings ). Little attention has been paid to the very properties of spatial entities, their status in linguistic descriptions, and their implications for spatial cognition and its development in children. This topic is at the center of this book, that opens a new field by sketching some major theoretical and methodological directions for future research on spatial entities. Brought together linguistic descriptions of spatial systems, formal accounts of linguistic data, and experimental findings from psycholinguistic studies, all couched within a wide cross-linguistic perspective. Such an interdisciplinary approach provides a rich overview of the many questions that remain unanswered in relation to spatial entities, while also throwing a new light on previous research focusing on related topics concerning space and/or the relation between language and cognition.

This book constitutes the refereed proceedings of the International Conference on Spatial Cognition, Spatial Cognition 2008, held in Freiburg, Germany, in September 2008. The 27 revised full papers presented together with 3 invited lectures were carefully reviewed and selected from 54 submissions. The papers are organized in topical sections on spatial orientation, spatial navigation, spatial learning, maps and modalities, spatial communication, spatial language, similarity and abstraction, concepts and reference frames, as well as spatial modeling and spatial reasoning.

This book is the third to appear in the SIBIL series based on results from the European Science Foundation's Additional Activity on the second language acquisition of adult immigrants. It analyses from a longitudinal and cross-linguistic perspective the acquisition of the linguistic means to express spatial relations in the target languages English, French and German. Learners' progress in the expression of spatial relations is closely followed over a period of 30 months using a wide range of oral data, and the factors determining both the specifics of individual source/target language pairings, and the general characteristics of all cases of acquisition studied, are carefully described. In particular, a basic system for the expression of spatial relations common to all learners from all language backgrounds is identified. The book is of particular significance for the field of second language acquisition in that this is the first time that results are presented in English on the acquisition of L2 means to express the basic cognitive — and communicational — category of space from a comparative linguistic point of view.

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.
