This volume contains the papers from the technical programmeof the 5th Eu- pean Semantic Web Conference, ESWC 2008, that took place during June 1-5, 2008 in Tenerife, Islas Canarias, Spain. ESWC 2008 was the latest in a series of annual, international events foc- ing on the dissemination and discussion of the latest research and applications of Semantic Web technologies. The call for papers saw over 270 submissions, a comparable ?gure to the previous year, indicating that the conference series has reached a certain level of maturity. The review process was organized - ing a two-tiered system. First, each submission was reviewed by at least three members of the ProgrammeCommittee. Submissions were also assignedto a - niorProgrammeCommitteemember, wholed discussionsbetweenreviewersand provided a metareview and provisional decision. A physical Programme C- mittee meeting was then held, where the ?nal decisions weremade. Competition was as strong as ever, and the Programme Committee selected 51 papers to be presented at the conference. In addition to the technical research paper track, a system demo track was included, withits ownreviewprocess. Twenty-?vedemo paperswereselectedfor publication. System demo authors were given the opportunity to present their workin dedicated sessionsduring the conference, while anevening receptionwas also devoted to the presentation of posters and demonstrations of systems. As in past years, ESWC subscribed to the call to "eat our own dog food," withthepublicationofarichsetofsemanticmetadatadescribingtheconference. Three invited talks were given by distinguished scientists: Nigel Shadbolt (Garlik Ltd.

Ruby has set the world on fire, proving itself a serious challenger to Perl and Python in all spheres. In particular, more and more people are discovering that Ruby's flexibility, superb feature set, and gentle learning curve make it a natural choice for system administration tasks, from the humblest server to the largest enterprise deployment.

Within the pages of Practical Ruby for System Administration, you'll learn the Ruby way to construct files, tap into clouds of data, build domain-specific languages, perform network traffic analysis, and more.

Based on author Andre Ben Hamou 's own experiences working as a system administrator, this book will help you pick up practical tips on Ruby coding style, learn how to analyze and improve script performance, and make use of no-nonsense advice on scripting workflow, including testing and documentation.

Above all, you'll come to appreciate the sheer power of Ruby and the hundreds of benefits it offers for system administration.This book places equal emphasis on fundamental Ruby concepts as well as practical how-tos. It uses examples from other languages to ease the transition to Ruby. The book is concise, entertaining, and informativeunlike many books aimed at system administrators, which can be overly long and stodgy.

The widespread deployment of millions of current and emerging software applications has placed software economic studies among the most critical of any form of business analysis. Unfortunately, a lack of an integrated suite of metrics makes software economic analysis extremely difficult. The International Function Point Users Group (IFPUG), a nonprofit and member-governed organization, has become the recognized leader in promoting the effective management of application software development and maintenance activities. The IFPUG Guide to IT and Software Measurement brings together 52 leading software measurement experts from 13 different countries who share their insights and expertise. Covering measurement programs, function points in measurement, new technologies, and metrics analysis, this volume: Illustrates software measurement's role in new and emerging technologies Addresses the impact of agile development on software measurement Presents measurement as a powerful tool for auditing and accountability Includes metrics for the CIO Edited by IFPUG's Management and Reporting Committee, the text is useful for IT project managers, process improvement specialists, measurement professionals, and business professionals who need to interact with IT professionals and participate in IT decision-making. It includes coverage of cloud computing, agile development, quantitative project management, process improvement, measurement as a tool in accountability, project ROI measurement, metrics for the CIO, value stream mapping, and benchmarking.

Time delay systems exist in many engineering ?elds such as transportation, communication, process engineering and more recently networked control s- tems. In recent years,time delaysystems haveattracted recurring interests from research community. Much of the research work has been focused on stability analysis and stabilization of time delay systems using the so-called Lyapunov- Krasovskii functionals and linear matrix inequality (LMI) approach. While the LMI approach does provide an e?cient tool for handling systems with delays in state and/or inputs, the LMI based results are mostly only su?cient and only numerical solutions are available. For systems with knownsingle input delay, there have been rather elegant- alytical solutions to various problems such as optimal tracking, linear quadratic regulation and H control. We note that discrete-time systems with delays can ? usually be converted into delay free systems via system augmentation, however, theaugmentationapproachleadsto muchhigher computationalcosts,especially for systems of higher state dimension and large delays. For continuous-time s- tems,time delayproblemscaninprinciple betreatedby thein?nite-dimensional system theory which, however,leads to solutions in terms of Riccati type partial di? erential equations or operator Riccati equations which are di?cult to und- stand and compute. Some attempts have been made in recent years to derive explicit and e?cient solutions for systems with input/output (i/o) delays. These include the study ontheH controlofsystemswith multiple input delaysbased ? on the stable eigenspace of a Hamlitonian matrix [46].

Addressing the unique difficulties involved in day-to-day project management communication, The Project Manager's Communication Toolkit provides proven methods for creating clear and effective communications-including text-based plans, reports, messages, and presentations. It examines the many tools available and goes beyond traditional coverage to define their proper use and application. Using language that's easy to understand, the author explains how to determine the appropriate tools for specific communication needs. This time-saving resource provides the understanding to harness the power of everyday communication, such as email and PowerPoint (R) to: Gain control over project parameters Overcome conflict Create effective project plans, charters, and statements of work Considering that most projects fail due to lapses in communication, it is essential for project managers to understand how to communicate their plans and ideas clearly and effectively. Complete with numerous examples and case studies, this book provides the understanding required to select the right tools, as well as the insight to use those tools effectively in a wide range of real-world situations. Praise for: ... a 'slam dunk' in providing the reader a foundation, emphasizing various tools, techniques; and in which situations they should be applied. The case studies further challenge the day-to-day situations one may face; providing techniques that work! Anyone that has been part of a project team will benefit from this book.-Lisa Holowiak, Quality Assurance Specialist, Pfizer, in PM World Today, Vol. XII, Issue X ... a valuable resource for program and project managers at all levels and all industries.

Economics and technology have dramatically re-shaped the landscape of software development. It is no longer uncommon to find a software development team dispersed across countries or continents. Geographically distributed development challenges the ability to clearly communicate, enforce standards, ensure quality levels, and coordinate tasks. Global Software Development Handbook explores techniques that can bridge distances, create cohesion, promote quality, and strengthen lines of communication. The book introduces techniques proven successful at international electronics and software giant Siemens AG. It shows how this multinational uses a high-level process framework that balances agility and discipline for globally distributed software development. The authors delineate an organizational structure that not only fosters team building, but also achieves effective collaboration among the central and satellite teams. The handbook explores the issues surrounding quality and the processes required to realize quality in a distributed environment. Communication is a tremendous challenge, especially for teams separated by several time zones, and the authors elucidate how to uncover patterns of communication among these teams to determine effective strategies for managing communication. The authors analyze successful and failed projects and apply this information to how a project can be successful with distributed teams. They also provide lightweight processes that can be dynamically adapted to the demands of any project.

Its scale, flexibility, cost effectiveness, and fast turnaround are just a few reasons why crowdsourced testing has received so much attention lately. While there are a few online resources that explain what crowdsourced testing is all about, there's been a need for a book that covers best practices, case studies, and the future of this technique. Filling this need, Leveraging the Wisdom of the Crowd in Software Testing shows you how to leverage the wisdom of the crowd in your software testing process. Its comprehensive coverage includes the history of crowdsourcing and crowdsourced testing, implementation practices, and future trends. The book discusses best practices in implementation-explaining what, when, and how to crowdsource in a testing effort. It also includes case studies that illustrate how both product and service companies have successfully applied crowdsourcing in their testing programs. Explaining how to use the combined advantages of crowdsourcing and cloud computing for software testing, the book examines various engagement models in which you could implement crowdsourced testing. It addresses effective defect management in crowdsourced testing and considers both the business and engineering aspects of crowdsourced testing. The book explores the challenges, limitations, and situations when crowdsourced testing will not work and provides powerful best practices for mitigating the constraints and challenges, including how to build a crowdsourcing platform to test software products. Covering career opportunities for crowd testers, the book concludes by taking a look at the need to build a crowdsourced testing ecosystem, who the players of such an ecosystem would be, and who would need to champion such an effort.

Whether you use budget, schedule, quality, or other criteria, the statistics by think tanks, institutes, associations, and other trade organizations all point to one inescapable conclusion: your project has a greater chance of getting into trouble than staying out of it. Based on the lessons learned by the author during a quarter of a century of leading projects to successful conclusions, Managing Projects in Trouble: Achieving Turnaround and Success unveils the five secrets to ensuring success-even for projects seemingly doomed to fail. Using numerous flow diagrams and checklists, it explains how to take action in ways that will increase the likelihood of success and minimize the possibility of failure. Specifically, it shows you how to: Recognize the symptoms of troubled projects Revisit your project's vision and execute an improved vision Examine all options for turning your project into a reality Choose the options most appropriate to your situation Supplying step-by-step guidance through each phase, the book explains how to spot the symptoms of troubled projects early on and arms you with time-tested techniques to address the problems that will inevitably emerge. Each chapter includes a case study that illustrates real-world implementation of the actions and steps discussed as well as a checklist to help ease the transition from project failure to surefire success. Learn the five secrets for turning troubled projects around detailed in this book-or continue what you're doing at your own peril.

In Rethinking Information Systems in Organizations John Paul Kawalek challenges the current orthodoxy of information systems and proposes new alternatives. Bold and ambitious, this book tackles the thorny issues of integration of disciplines, cross over of functions, and negotiation of epistemological divides in IS. Historically, the IS discipline has struggled to embrace and integrate technical as well as organizational knowledge, skills and methods. Kawalek argues that there are now a new set of imperatives that will irrecoverably change IS, affecting the way many organizations deploy and access their information and technology. This book defines how the traditional practices of Information Systems are required to integrate into a process of organizational problem-solving. An essential read for students of business information systems, organizational theory and research methods, Kawalek's work also provides core methodological principles on organizational change and problem solving, and presents an effective rationale for their use in Information Systems contexts.

This book provides emergent knowledge relating to physical, cyber, and human risk mitigation in a practical and readable approach for the corporate environment. It presents and discusses practical applications of risk management techniques along with useable practical policy change options. This practical organizational security management approach examines multiple aspects of security to protect against physical, cyber, and human risk. A practical more tactical focus includes managing vulnerabilities and applying countermeasures. The book guides readers to a greater depth of understanding and action-oriented options.

Adequate information security is one of the basic requirements of all electronic business processes. It is crucial for effective solutions that the possibilities offered by security technology can be integrated with the commercial requirements of the applications. Here the positions of the experts involved are very diverse: some strive for as much security as possible, others only for as much security as is necessary.

The conference ISSE (Information Security Solutions Europe) is the outstanding forum for the interdisciplinary search for sustainable compromises and for the presentation of concepts which hold up in real life. This book offers the most recent papers in the area of strategies, technologies, applications and best practice.

The Information Security Solutions Europe Conference (ISSE) was started in 1999 by EEMA and TeleTrusT with the support of the European Commission and the German Federal Minis try of Technology and Economics. Today the annual conference is a fixed event in every IT security professional's calendar. The aim of ISSE is to support the development of a Euro pean information security culture and especially a cross-border framework for trustworthy IT applications for citizens, industry and administration. Therefore, it is important to take into consideration both international developments and European regulations and to allow for the interdisciplinary character of the information security field. In the five years of its existence ISSE has thus helped shape the profile of this specialist area. The integration of security in IT applications was initially driven only by the actual security issues considered important by experts in the field; currently, however, the economic aspects of the corresponding solutions are the most important factor in deciding their success. ISSE offers a suitable podium for the discussion of the relationship between these considerations and for the presentation of the practical implementation of concepts with their technical, or ganisational and economic parameters."

In recent years we have witnessed the explosion of multimedia traffic on the Internet. The availability of high bandwidth connections together with the recent advances in high quality video and audio compression techniques have created a fertile ground for the growth of multimedia applications such as interactive video on demand, collaborative distance learning, and remote medical diagnosis. Furthermore, the availability of low bit rate video and audio applications (e.g., H.263 and G.728) and the proliferation of pervasive devices create a new demand for wireless multimedia communication systems. After a decade or more of research and development in multimedia networking, the research community has learned a number of lessons. First, increasing the capacity of the "best effort" networks and services does not provide an effective and permanent solution for offering a guaranteed Quality of Service (QoS). Second, the integration of service and network management is a key element in providing end to end service management. Third, management techniques for Internet multimedia services must be scalable and adaptive to guarantee QoS and maintain fairness with optimal network resource.

These are the proceedings of the second symposium on Generative and C- ponent-Based Software Engineering that was held in Erfurt, Germany, on - tober 9-12, 2000, as part of the Net. Object Days conference. The GCSE s- posium was born in 1999 at the Smalltalk and Java in Industry and Edu- tion Conference (STJA), the precursor to the Net. Object Days conference. The GCSE symposium grew out of a special track on generative programming that was organized by the working group "Generative and Component-Based So- ware Engineering" of the "Gesellschaft fur .. Informatik" FG 2. 1. 9 at STJA in the two years 1997 and 1998. The GCSE symposium covers a wide range of related topics from domain analysis, software system family engineering, and software product lines, to extendible compilers and active libraries. The second GCSE symposium attracted 29 submissions from all over the world. This impressive number demonstrates the international interest in g- erative programming and related ?elds. After a careful review by the program committee, 12 papers were selected for presentation. We are very grateful to the members of the program committee, all of them renowned experts, for their dedication in preparing thorough reviews of the submissions. Special thanks go to Elke Pulvermuller .. , Andreas Speck, Kai B.. ollert, Detlef Streitferdt, and Dirk Heuzeroth, who continued the tradition from GCSE'99 and organized a special conference event, the Young Researchers Workshop (YRW).
