Book Qualitative Representation of Spatial Knowledge

Download or read book Qualitative Representation of Spatial Knowledge written by Daniel Hernandez and published by Springer Science & Business Media. This book was released on 1994-06-28 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book develops, for the first time, a qualitative model for the representation of spatial knowledge based only on locative relations between the objects involved. The core of this book is devoted to the study of qualitative inference methods that take into account the rich structure of space. These methods can be applied to quite a number of areas characterized by uncertain or incomplete knowledge, as for example geographic information systems, robot control, computer-aided architectural design, and natural language information systems.

Book Qualitative Spatial Reasoning with Topological Information

Download or read book Qualitative Spatial Reasoning with Topological Information written by Jochen Renz and published by Springer. This book was released on 2003-07-31 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial knowledge representation and reasoning with spatial knowledge are relevant issues for many application areas such as robotics, geographical information systems, and computer vision. Exceeding purely quantitative approaches, more recently initiated qualitative approaches allow for dealing with spatial information on a more abstract level that is closer to the way humans think and speak. Starting out with the qualitative, topological constraint calculus RCC8 proposed by Randell, Cui, and Cohn, this work presents answers to a variety of open questions regarding RCC8. The open issues concerning computational properties are solved by exploiting a broad variety of results and methods from logic and theoretical computer science. Questions concerning practical performance are addressed by large-scale empirical computational experiments. The most impressive result is probably the complete classification of computational properties for all fragments of RCC8.

Book Qualitative Spatial Reasoning

Download or read book Qualitative Spatial Reasoning written by M. Teresa Escrig and published by IOS Press. This book was released on 1998 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the aim of automatically reasoning with spatial aspects in a cognitive way, several qualitative models have been developed recently in the Qualitative Spatial Reasoning field. However, there is no model to reason with several spatial aspects in a uniform way. Moreover, most of these models simplify spatial objects to points. In this book we present a novel approach for integrating the qualitative concepts of orientation, distance, and cardinal directions, using points as well as extended objects as primitive of reasoning, based on Constraint Logic Programming. The resulting model has been applied to build a qualitative Navigation Simulator on the structured environment of the city of Castellon.

Book Mental Representation and Processing of Geographic Knowledge

Download or read book Mental Representation and Processing of Geographic Knowledge written by Thomas Barkowsky and published by Springer. This book was released on 2003-07-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: In cognitive science, mental representations of spatial knowledge are metaphorically referred to as cognitive maps. However, investigations in cognitive psychology reveal that the cognitive map metaphor is inadequate and that more suitable conceptions of human spatial knowledge processing are needed. This book addresses mental processing of knowledge about geographic space from an AI point of view by presenting an experimental computational modeling approach. Results about human memory and visual mental imagery from cognitive psychology are combined with AI techniques of spatial and diagrammatic knowledge processing. The author develops the diagrammatic reasoning architecture MIRAGE as a comprehensive conception of human geographic knowledge processing.

Download or read book Spatial Cognition written by Christian Freksa and published by Springer. This book was released on 2003-05-20 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on spatial cognition is a rapidly evolving interdisciplinary enterprise for the study of spatial representations and cognitive spatial processes, be they real or abstract, human or machine. Spatial cognition brings together a variety of - search methodologies: empirical investigations on human and animal orientation and navigation; studies of communicating spatial knowledge using language and graphical or other pictorial means; the development of formal models for r- resenting and processing spatial knowledge; and computer implementations to solve spatial problems, to simulate human or animal orientation and navigation behavior, or to reproduce spatial communication patterns. These approaches can interact in interesting and useful ways: Results from empirical studies call for formal explanations both of the underlying memory structures and of the processes operating upon them; we can develop and - plement operational computer models obeying the relationships between objects and events described by the formal models; we can empirically test the computer models under a variety of conditions, and we can compare the results to the - sults from the human or animal experiments. A disagreement between these results can provide useful indications towards the re nement of the models.

Book Representation and Processing of Knowledge About Distances in Environmental Space

Download or read book Representation and Processing of Knowledge About Distances in Environmental Space written by Bettina Berendt and published by IOS Press. This book was released on 1999 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge about distances---along with knowledge about spatial direction---is one of the most important fundamentals for a cognitive agent's orientation, navigation, and route planning. However, only some distances can be perceived directly. Therefore, knowledge about distances must often be inferred from other sources of information. In cognitive science research on spatial cognition, this is investigated in different ways, using empirical studies, computer simulations, and knowledge representation approaches. This book presents a comprehensive interdisciplinary study of human distance cognition. It discusses results on knowledge about distances from artificial intelligence research and cognitive psychology, proposing an integrating formal framework. Focusing on knowledge about route distances, it then presents a computational model of the way in which humans infer knowledge about distances in environmental spaces like cities or buildings.

Available in PDF, EPUB and Kindle. Book excerpt: This volume collects the papers presented at the European Conference on Spatial Information Theory (COSIT '93) held on the island of Elba, Italy, inSeptember 1993. Spatial information theory includes disciplinary topics and interdisciplinary issues dealing with the conceptualization and formalization of large-scale (geographic) space. It contributes towards a consistent theoretical basis for Geographic Information Systems (GIS). Geographic information systems are widely used in administration,planning, and science in many different countries, and for a wide variety ofapplications. Research results which relevant for GIS are distributed between many disciplines and contacts between researchers have been limited. At the same time, the development of GIS has been hinderedby the lack of a sound theoretical base. This conference was intended to help remedies these problems.

Book Spatial and Temporal Reasoning

Download or read book Spatial and Temporal Reasoning written by O. Stock and published by Springer Science & Business Media. This book was released on 2007-07-27 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Qualitative reasoning about space and time - a reasoning at the human level - promises to become a fundamental aspect of future systems that will accompany us in daily activity. The aim of Spatial and Temporal Reasoning is to give a picture of current research in this area focusing on both representational and computational issues. The picture emphasizes some major lines of development in this multifaceted, constantly growing area. The material in the book also shows some common ground and a novel combination of spatial and temporal aspects of qualitative reasoning. Part I presents the overall scene. The chapter by Laure Vieu is on the state of the art in spatial representation and reasoning, and that by Alfonso Gerevini gives a similar survey on research in temporal reasoning. The specific contributions to these areas are then grouped in the two main parts. In Part II, Roberto Casati and Achille Varzi examine the ontological status of spatial entities; Anthony Cohn, Brandon Bennett, John Gooday, and Nicholas Gotts present a detailed theory of reasoning with qualitative relations about regions; Andrew Frank discusses the spatial needs of geographical information systems; and Annette Herskovits focuses on the linguistic expression of spatial relations. In Part III, James Allen and George Ferguson describe an interval temporal logic for the representation of actions and events; Drew McDermott presents an efficient way of predicting the outcome of plan execution; and Erik Sandewall introduces a semantics based on transitions for assessing theories of action and change. In Part IV, Antony Galton's chapter stands clearly between the two areas of space and time and outlines the main coordinates of an integrated approach.

Book Spatial Cognition IV  Reasoning  Action  Interaction

Download or read book Spatial Cognition IV Reasoning Action Interaction written by Christian Freksa and published by Springer. This book was released on 2005-02-22 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the fourth volume in a series of books dedicated to basic research in spatial cognition. Spatial cognition is a field that investigates the connection between the physical spatial world and the mental world. Philosophers and researchers have p- posed various views concerning the relation between the physical and the mental worlds: Plato considered pure concepts of thought as separate from their physical manifestations while Aristotle considered the physical and the mental realms as two aspects of the same substance. Descartes, a dualist, discussed the interaction between body and soul through an interface organ and thus introduced a functional view that presented a challenge for the natural sciences and the humanities. In modern psych- ogy, the relation between the physical and the cognitive space has been investigated using thorough experiments, and in artificial intelligence we have seen views as diverse as ‘problems can be solved on a representation of the world’ and ‘a representation of the world is not necessary. ’ Today’s spatial cognition work establishes a correspondence between the mental and the physical worlds by studying and exploiting their interaction; it investigates how mental space and spatial “reality” join together in understanding the world and in interacting with it. The physical and representational aspects are equally important in this work. Almost all topics of cognitive science manifest themselves in spatial cognition.
