A network is a mathematical object consisting of a set of points (called vertices or nodes) that are connected to each other in some fashion by lines (called edges). Turns out this simple description corresponds to a bewildering array of systems in the real world, ranging from technological ones such as the Internet and World Wide Web, biological networks such as that of connections of the nervous systems or blood vessels, food webs, protein interactions, infrastructural systems such as networks of roads, airports or the power-grid, to patterns of social acquaintance such as friendship, network of Hollywood actors, connections between business houses and many more. Recent years have witnessed a substantial amount of interest within the scientific community in the properties of these networks. The emergence of the internet in particular, coupled with the widespread availability of inexpensive computing resources has facilitated studies ranging from large scale empirical analysis of networks in the real world, to the development of theoretical models and tools to explore the various properties of these systems. The study of networks is broadly interdisciplinary and central developments have occurred in many fields, including mathematics, physics, computer and information sciences, biology, and the social sciences. This book brings together a collection of cutting-edge research in the field from a diverse array of researchers ranging from physicists to social scientists, and presents them in a coherent fashion, highlighting the strong interconnections between the different areas. Topics included are social networks and social media, opinion and innovation diffusion, syncronization, transportation networks and human mobility, as well as theory, modeling and metrics of Complex Networks.

This book constitutes the refereed proceedings of the 12th International Conference on Web Engineering, ICWE 2012, held in Berlin, Germany, in July 2012. The 20 revised full papers and 15 short papers were carefully reviewed and selected from 98 submissions. The papers are organized in topical sections on social networks and collaboration, tagging, personalization and personal systems, search, Web modeling, AJAX and user interfaces, Web services, Web crawling, and Web and linked data management. The book also includes 6 poster papers, 12 demos and 5 tutorials.

As today's most complex computing environment, the Internet confronts IT researchers, system designers, and application developers with completely new challenges and, as a fascinating new computing paradigm, agent technology has recently attracted broad interest and strong hopes for shaping the future information society. Relating both, the Internet and agents, opens up a whole new range of advanced applications in vibrant subfields of information technology such as middleware, mobile commerce, e-learning, collaborative working, and intelligent information services. Many modern advanced systems are likely to exploit Internet agents - and exploiting Internet agents mostly means dealing with coordination models and technologies of various sorts. This monograph-like anthology is the first systematic guide to models and enabling technologies for the coordination of intelligent agents on the Internet and respective applications.

BIS 2010 held on 3-5 May 2010 in Berlin, Germany was the 13th in a series of international conferences on Business Information Systems. The BIS conference series has been recognised by professionals from its very beginning as a forum for the exchange and dissemination of topical research in the development, - plementation, application and improvement of computer systems for business processes. The theme ofthe conferencewas"Future InternetBusiness Services." A n- ber of new initiatives are already underway to address the challenges related to explosive development of Internet applications, hence the conference topics: Searchand KnowledgeSharing,Data and InformationSecurity,Web Experience Modelling. Although many people announced that SOA was dead there is - doubtedly a strong need for service-orientation. This was addressed by a topic: Services and Repositories. More and more e?ort is put on explaining and und- standing complex processes as could be seen in topics: Business Processes and Rules, Data Mining for Processes, Visualisation in BPM. Finally, the classical business aspects were covered in session: ERP and SCM. Altogether, a set of 25 papers illustrating these trends were selected for the presentation during the main event, grouped in 8 sessions. The Program C- mittee consisted of almost 100 members who carefully evaluated all the subm- ted papers. Each submission was reviewed on the average by 3.1 programme committee members. Only the best quality papers were selected, resulting in an acceptance rate of less than 30%.

This book contains a collection of thoroughly revised tutorial papers based on lectures given by leading researchers at the Second International Summer School on the Reasoning Web in Dresden, Germany, September 3-7, 2007. The objective of the book is to provide a coherent introduction to Semantic Web methods and research issues with a particular focus on reasoning.

The nine tutorial papers presented provide competent coverage of methods and research issues of the Semantic Web, ontology languages and their relation to description logics, Web query languages, XML, RDF and Topics Maps, evolution and reactivity, personalization in the Semantic Web, rule modeling with UML, techniques in Web information extraction, employing ontologies to ease construction of software applications, and type checking for Web rule and query languages.

This book constitutes the thoroughly refereed post-proceedings of the Third International Workshop on Engineering Societies in the Agents World, ESAW 2003, held in Madrid, Spain in September 2002. The 20 revised full papers presented were carefully selected from 35 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on views, models, engineering, and modeling and design.

This book constitutes the thoroughly refereed post-proceedings of the Second International Workshop on Engineering Societies in the Agents World, ESAW 2001, held in Prague, Czech Republic in July 2001. The 12 revised full papers presented together with a survey by the volume editors were carefully selected during two rounds of reviewing and improvement. The papers are organized in topical sections on foundations of engineering with agents, logics and languages for MAS engineering, and agent middleware and applications.

This book constitutes the thoroughly refereed post-proceedings of the First International Workshop on Engineering Societies in the Agents World, ESAW 2000, held in Berlin, Germany in August 2000. The 10 revised full papers presented were carefully reviewed and selected for inclusion in the book; they are organized in topical sections on emerging issues in multi-agent systems engineering, coordination models and technologies for multi-agent systems, and methodologies and tools.

The state of the art in ontology building, and modeling in general, widely disregards the fact that the behavior of rational actors in the modeling process will be driven by individual economic incentives. Creating an ontology requires resources (e.g. labor) from the contributing individuals. If there is a remote possibility the overall benefit of an ontology might exceed the costs for creating the ontology over its lifetime, it may not be created if ita (TM)s not economically feasible for each individual required to contribute.

Ontology Economics, an edited volume authored by distinguished leaders in this field, provides a one-stop reference on the economic dimension of building, committing to, and using ontologies which are grounded by economic research. Linked to experience and data from real-world ontology projects, this volume is concise and self-contained.

A reference book for advanced-level students and researchers in computer science and engineering; also useful for industry practitioners.
