Due to differences in the legal systems and business environments, it is difficult to compare the process of buying and selling land in different European countries. Illustrated by a range of European case studies, this book identifies and discusses the problems of this and similar comparisons. It then examines how ontological modelling can be applied to real estate transactions and advocates this as a basis for comparing the various processes used across Europe. The book consists of four parts: the economic, legal and ontological aspects of real property transactions; a discussion of the current situation in different countries, thus showing the heterogeneity and complexity of processes that have to be captured; whilst the third and fourth parts describe ontological modelling and its benefits for the purpose of understanding the nature of real property transactions together with examples of modelling techniques applied to cadastre and real property.

The large-scale and almost ubiquitous availability of information has become as much of a curse as it is a blessing. The more information is available, the harder it is to locate any particular piece of it. And even when it has been successfully found, it is even harder still to usefully combine it with other information we may already possess. This problem occurs at many different levels, ranging from the overcrowded disks of our own PCs to the mass of unstructured information on the World Wide Web.It is commonly understood that this problem of information sharing can only be solved by giving computers better access to the semantics of the information. While it has been recognized that ontologies play a crucial role in solving the open problems, most approaches rely on the existence of well-established data structures. To overcome these shortcomings, Stuckenschmidt and van Harmelen describe ontology-based approaches for resolving semantic heterogeneity in weakly structured environments, in particular the World Wide Web.Addressing problems like missing conceptual models, unclear system boundaries, and heterogeneous representations, they design a framework for ontology-based information sharing in weakly structured environments like the Semantic Web.For researchers and students in areas related to the Semantic Web, the authors provide not only a comprehensive overview of the State of the art, but also present in detail recent research in areas like ontology design for information integration, metadata generation and management, and representation and management of distributed ontologies. For professionals in areas such as e-commerce (e.g., the exchange of product knowledge) and knowledge management (e.g., in large and distributed organizations), the book provides decision support on the use of novel technologies, information about potential problems, and guidelines for the successful application of existing technologies.

Just like the industrial society of the last century depended on natural resources, today’s society depends on information and its exchange.Staab and Stuckenschmidt structured the selected contributions into four parts: Part I, "Data Storage and Access", prepares the semantic foundation, i.e. data modelling and querying in a flexible and yet scalable manner. These foundations allow for dealing with the organization of information at the individual peers. Part II, "Querying the Network", considers the routing of queries, as well as continuous queries and personalized queries under the conditions of the permanently changing topological structure of a peer-to-peer network. Part III, "Semantic Integration", deals with the mapping of heterogeneous data representations. Finally Part IV, "Methodology and Systems", reports experiences from case studies and sample applications.The overall result is a state-of-the-art description of the potential of Semantic Web and peer-to-peer technologies for information sharing and knowledge management when applied jointly.

The growing emphasis on complexity concerns for ontologies has attracted signi cant interest from both the researchers' and the practitioners' communities in modularization techniques as a way to decrease the complexity of managing huge ontologies.Researchhasproducedmanycomplementaryandcompetingapproaches, mainly with the goal of supportingpractitioners' methodologieswith sound and p- cisely de nedfoundationsand alternatives.Existing prototypessubstantiate research results and experimental evaluations have been performed. Thus, a large body of work is available. This book has been designed to provide the reader with a detailed analysis of where we stand today and which concepts, theories and techniques for knowledge modularization we can con dently rely on. The material for the book has been - lected from research achievements that are mature enough to be considered as a rm and reliable basis on which to inspire further work and to develop solutions in c- crete environments. The content of the book has been organized in three parts. Part I holds a general introductionto theidea andissuescharacterizingmodularization.Thisisfollowedby three chapters that offer an in-depth analysis of properties, criteria and knowledge import techniques for modularization.The last chapter discusses one of the three approaches that implement the modularization idea. The two other approaches are covered in detail in parts II and III.

Beginnend mit den grundlegenden Konzepten und Ideen von Ontologien, die der Philosophie und Linguistik entstammen, stellt das Buch den aktuellen Stand der Technik im Bereich unterstützender Technologien aus der Semantic Web Forschung dar und zeigt vielversprechende Anwendungsbiete auf.

This volume contains papers from the technical program of the 7th Extended Semantic Web Conference (ESWC 2010), held from May 30 to June 3, 2010, in Heraklion, Greece. ESWC 2010 presented the latest results in research and applications of Semantic Web technologies. ESWC 2010 built on the success of the former European Semantic Web Conference series, but sought to extend its focus by engaging with other communities within and outside Information and Communication Technologies, in which semantics can play an important role. At the same time, ESWC has become a truly international conference. Semantics of Web content, enriched with domain theories (ontologies), data about Web usage, natural language processing, etc., will enable a Web that p- vides a qualitatively new level of functionality. It will weave together a large network of human knowledge and make this knowledge machine-processable. Various automated services, based on reasoning with metadata and ontologies, will help the users to achieve their goals by accessing and processing infor- tion in machine-understandable form. This network of knowledge systems will ultimately lead to truly intelligent systems, which will be employed for va- ous complex decision-making tasks. Research about Web semantics can bene?t from ideas and cross-fertilization with many other areas: arti?cial intelligence, natural language processing, database and information systems, information - trieval, multimedia, distributed systems, social networks, Web engineering, and Web science.
