By introducing Semantic Web technologies into geospatial Web services, this book addresses the semantic description of geospatial data and standards-based Web services, discovery of geospatial data and services, and generation of composite services. Semantic descriptions for geospatial data, services, and geoprocessing service chains are structured, organized, and registered in geospatial catalogue services. The ontology-based approach helps to improve the recall and precision of data and services discovery. Semantics-enabled metadata tracking and satisfaction allows analysts to focus on the generation of a geospatial process model rather than spending large amounts of time in data preparation. “DataType”-driven service composition and path planning can help to automate a range of knowledge discovery processes in a limited geospatial domain. Process planning facilitates the construction of complex services and models for geocomputation. A three-phase procedure to cover the lifecycle of service chaining and to identify the roles of the methods involved is proposed. It includes process modeling, process model instantiation, and workflow execution. The approach is implemented in a prototype system with use cases to demonstrate applicability. The objective of the research is to develop the key technologies for an intelligent geospatial knowledge system based on Web services to automate the data discovery and data preprocessing steps in the distributed Web service environment, to automate a range of knowledge discovery processes in a limited geospatial domain, using the automated construction and execution of service chains, and to facilitate the construction of complex services and models for geocomputation.

Semantic Webs promise to revolutionize the way computers find and integrate data over the internet. They will allow Web agents to share and reuse data across applications, enterprises, and community boundaries. However, this improved accessibility poses a greater threat of unauthorized access, which could lead to the malicious corruption of information. Building Trustworthy Semantic Webs addresses the urgent demand for the development of effective mechanisms that will protect and secure semantic Webs. Design Flexible Security Policies to Improve Efficiency Securing semantic Webs involves the formation of policies that will dictate what type of access Web agents are allowed. This text provides the tools needed to engineer these policies and secure individual components of the semantic Web, such as XML, RDF, and OWL. It also examines how to control unauthorized inferences on the semantic Web. Since this technology is not fully realized, the book emphasizes the importance of integrating security features into semantic Webs at the onset of their development. Through its expansive coverage, Building Trustworthy Semantic Webs describes how the creation of semantic security standards will ensure the dependability of semantic Webs. It provides Web developers with the tools they need to protect sensitive information and guarantee the success of semantic Web applications.

A universal approach to the ontology of geographic space has already been, and is going to be, a comprehensive task for establishing more effective spatial models. The concept of a universal spatial ontology should be independent of location, culture, and time. It should be fundamental and universal in the same way that the number p defines the ratio between the diameter and the circumference of a circle. The term “universal” therefore means all-embracing and for general propose. Universal Ontology of Geographic Space: Semantic Enrichment for Spatial Data aims to escalate the current scope of research to support the development of semantically interoperable systems of geographic space. This reference will aid university lecturers and professors, students, researchers, developers of spatial applications.

Geographic information systems (GIS) have spurred a renewed interest in the influence of geographical space on human behavior and cultural development. Ideally GIS enables humanities scholars to discover relationships of memory, artifact, and experience that exist in a particular place and across time. Although successfully used by other disciplines, efforts by humanists to apply GIS and the spatial analytic method in their studies have been limited and halting. The Spatial Humanities aims to re-orient—and perhaps revolutionize—humanities scholarship by critically engaging the technology and specifically directing it to the subject matter of the humanities. To this end, the contributors explore the potential of spatial methods such as text-based geographical analysis, multimedia GIS, animated maps, deep contingency, deep mapping, and the geo-spatial semantic web.

Inhaltsangabe:Gang der Untersuchung: Das Ziel der vorliegenden Studie ist es, die in den vergangenen Jahren entwickelten Technologien und Konzepte des Semantic Web auf Ihre praktische Anwendbarkeit zu testen. Die praktische Umsetzbarkeit wird an der Realisierung eines prototypischen Webapplikation aufgezeigt, welche grundlegende Projekt- und Workflowmanagementaktivitäten ermöglichen soll. Diese Anwendungsdomain ist momentan im Kontext des kollaborativen Arbeitens verbunden mit einer semantikbasierten Umsetzung hochaktuell, gleichzeitig aber auch so gut erforscht, dass auf eine Reihe fester Konzepte und Begrifflichkeiten zurückgegriffen werden kann, welche sich semantisch gut beschreiben lassen. Alle zu verarbeitenden Informationen in dem zu entwickelnden System werden in einem Pool aus verteilten (Web-)Dokumenten bereitgestellt, wobei die darin enthaltenen Daten mit zusätzlichen Informationen zur Beschreibung der Semantik versehen sind. Das gesamte System wird darauf ausgelegt, den kollaborativen Gedanken des Semantic Web bestmöglich umzusetzen. Es soll demonstriert werden, welche Möglichkeiten existieren, eine Problemstellung in einem lauffähigen System praktisch abzubilden, modellrelevante Informationen aus dazugehörigen Webdokumenten zu extrahieren und diese so aufzubereiten, dass sie einen Mehrwert für den Nutzer liefern können. Die Grundlagen von Projektmanagementsystemen sind in den letzten Jahrzehnten bereits gut erforscht worden, wodurch eine Vielzahl an Vergleichssystemen zur Verfügung steht, deren Stärken und Schwächen zunächst untersucht werden können und aus denen ein entsprechendes Grundvokabular abgeleitet werden kann. Das zu entwickelnde System hat schließlich der Anforderung zu genügen, durch eine einfache Bedienung den Menschen bei der täglichen Arbeit zu unterstützen, was im Kern das Grundanliegen der Informatik ist. Nachdem in diesem Einführungskapitel ein Überblick über den aktuellen Forschungsstand gegeben wurde, sollen in Kapitel 2 zunächst grundlegende Begriffe zur Realisierung eines Projektmanagementsystems geklärt sowie ein Überblick über im Einsatz befindliche Managementsysteme gegeben werden. Besonderer Wichtigkeit kommt dabei der Definition eines Grundvokabulars zu, welches für alle Beteiligten wohl unterscheidbare Konzepte umfasst. In Kapitel 3 schließlich werden die Ideen des Semantic Webs aus Kapitel 1 mit den Grundlagen des Projektmanagements aus Kapitel 2 verknüpft und ein Konzept erarbeitet, wie ein Semantic [...]

The 2nd Workshop on Web Services, E-Business, and the Semantic Web (WES) was held during June 16–17, 2003 in conjunction with CAiSE 2003, the 15th International Conference on Advanced Information Systems Engineering. The Internet is changing the way businesses operate. Organizations are using the Web to deliver their goods and services, to find trading partners, and to link their existing (maybe legacy) applications to other applications. Web services are rapidly becoming the enabling technology of today’s e-business and e-commerce systems, and will soon transform the Web as it is now into a distributed computation and application fra- work. On the other hand, e-business as an emerging concept is also impacting software - plications, the everyday services landscape, and the way we do things in almost each domain of our life. There is already a body of experience accumulated to demonstrate the difference between just having an online presence and using the Web as a stra- gic and functional medium in e-business-to-business interaction (B2B) as well as marketplaces. Finally, the emerging Semantic Web paradigm promises to annotate Web artifacts to enable automated reasoning about them. When applied to e-services, the paradigm hopes to provide substantial automation for activities such as discovery, invocation, assembly, and monitoring of e-services. But much work remains to be done before realizing this vision.

Most widely available approaches to semantic integration provide ad-hoc, non-systematic, subjective manual mappings that lead to procrustean amalgamations to fit the target standard, an outcome that pleases no one. Written by experts in the field, Theories of Geographic Concepts: Ontological Approaches to Semantic Integration emphasizes the real issues involved in integrating existing geo-ontologies. The book addresses theoretical, formal, and pragmatic issues of geographic knowledge representation and integration based on an ontological approach. The authors highlight the importance of philosophical, cognitive, and formal theories in preserving the semantics of geographic concepts during ontology development and integration. They elucidate major theoretical issues, then introduce a number of formal tools. The book delineates a general framework with the necessary processes and guidelines to ontology integration and applies it to a selection of ontology integration cases. It concludes with a retrospection of key issues and identifies open research questions. Copiously illustrated, the book contains more than 80 illustrations and several examples to various approaches that provide a better understanding of the complexity of ontology integration tasks. The authors provide guidance on selecting the most appropriate approach and details on its application to indicative integration problems.

Computer science provides a powerful tool that was virtually unknown three generations ago. Some of the classical fields of knowledge are geodesy (surveying), cartography, and geography. Electronics have revolutionized geodetic methods. Cartography has faced the dominance of the computer that results in simplified cartographic products. All three fields make use of basic components such as the Internet and databases. The Springer Handbook of Geographic Information is organized in three parts, Basics, Geographic Information and Applications. Some parts of the basics belong to the larger field of computer science. However, the reader gets a comprehensive view on geographic information because the topics selected from computer science have a close relation to geographic information. The Springer Handbook of Geographic Information is written for scientists at universities and industry as well as advanced and PhD students.
