Semantic Web: Grundlagen (eXamen.press)

by Pascal Hitzler Markus Krötzsch Sebastian Rudolph York Sure

Das Buch Semantic Web – Grundlagen vermittelt als erstes deutschsprachiges Lehrbuch die Grundlagen des Semantic Web in verständlicher Weise. Es ermöglicht einen einfachen und zügigen Einstieg in Methoden und Technologien des Semantic Web und kann z.B. als solide Grundlage für die Vorbereitung und Durchführung von Vorlesungen genutzt werden. Die Autoren trennen dabei sauber zwischen einer intuitiven Hinführung zur Verwendung semantischer Technologien in der Praxis einerseits, und der Erklärung formaler und theoretischer Hintergründe andererseits. Nur für letzteres werden Grundkenntnisse in Logik vorausgesetzt, die sich bei Bedarf jedoch durch zusätzliche Lektüre und mit Hilfe eines entsprechenden Kapitels im Anhang aneignen lassen. Das Lehrbuch richtet sich primär an Studenten mit Grundkenntnissen in Informatik sowie an interessierte Praktiker welche sich im Bereich Semantic Web fortbilden möchten. Aus den Rezensionen: "… RDF, RDF-S und OWL. Diese Sprachen … werden von den Autoren dargestellt. Bei der Darstellung … fallen sie selten zu schwierigen Fachslang, sondern liefern eine gut nachvollziehbare Schilderung mit einfachen Beispielen, auch Übungsaufgaben runden die Kapitel ab. … Semantic Web ist ein einfach geschriebenes und anschauliches Buch, das In die Grundkonzepte der Semantic-Web-Techniken einführt. Wer sich schnell in RDF, RDF-S und Co. einarbeiten muss und etwas Vorbildung in Logik und Algebra mitbringt, der trifft mit diesem Lehrbuch sicherlich eine gute Wahl …" (http://www.literaturnetz.com/content/view/8742/44/)

Open Digital Innovation: A Contest Driven Approach (Progress in IS)

by Anders Hjalmarsson Gustaf Juell-Skielse Paul Johannesson

This book explores how novel digital services, including e-services, digital platforms and mobile apps, are increasingly being innovated through open processes. It investigates how and why organizations invite external developers to participate in their innovation, often catalyzed by contests and the provision of open data, with the aim of designing digital services that go beyond the capability of the organizations themselves. Taking a contest driven approach to innovation, the book provides an accessible yet comprehensive introduction to the area of open digital innovation. It offers an analysis of key scientific principles underlying open innovation and based on these provides practical tools for improving the digital innovation process. Furthermore, the book introduces instruments for managing innovation contests, in particular for overcoming innovation barriers and for harnessing the power of motivating factors. It serves as a text for graduate and undergraduate courses in digital innovation and entrepreneurship, but is also a valuable resource for managers as well as policy makers in the field of open digital innovation.

Instruction Selection: Principles, Methods, and Applications

by Gabriel Hjort Blindell

This book presents a comprehensive, structured, up-to-date survey on instruction selection. The survey is structured according to two dimensions: approaches to instruction selection from the past 45 years are organized and discussed according to their fundamental principles, and according to the characteristics of the supported machine instructions. The fundamental principles are macro expansion, tree covering, DAG covering, and graph covering. The machine instruction characteristics introduced are single-output, multi-output, disjoint-output, inter-block, and interdependent machine instructions. The survey also examines problems that have yet to be addressed by existing approaches. The book is suitable for advanced undergraduate students in computer science, graduate students, practitioners, and researchers.

Games and Gaming: An Introduction to New Media (Berg New Media Series)

by Larissa Hjorth

The computer games industry has rapidly matured. Once a preoccupation only of young technophiles, games are now one of the dominant forms of global popular culture. From consoles such as Nintendo Wii and Microsoft Xbox to platforms such as iPhones and online gaming worlds, the realm of games and their scope has become all-pervasive.The study of games is no longer a niche interest but rather an integral part of cultural and media studies. The analysis of games reveals much about contemporary social relations, online communities and media engagement.Presenting a range of approaches and analytical tools through which to explore the role of games in everyday life, and packed with case material, Games and Gaming provides a comprehensive overview of this new media and how it permeates global culture in the twenty-first century.

Art in the Asia-Pacific: Intimate Publics (Routledge Advances in Art and Visual Studies)

by Larissa Hjorth Natalie King Mami Kataoka

As social, locative, and mobile media render the intimate public and the public intimate, this volume interrogates how this phenomenon impacts art practice and politics. Contributors bring together the worlds of art and media culture to rethink their intersections in light of participatory social media. By focusing upon the Asia-Pacific region, they seek to examine how regionalism and locality affect global circuits of culture. The book also offers a set of theoretical frameworks and methodological paradigms for thinking about contemporary art practice more generally.

Exploring Minecraft: Ethnographies of Play and Creativity (Palgrave Games in Context)

by Larissa Hjorth Ingrid Richardson Hugh Davies William Balmford

This book directs critical attention to one of the most ubiquitous and yet under-analyzed games, Minecraft. Drawing on three years of ethnographic fieldwork into mobile games in Australian homes, the authors seek to take Minecraft seriously as a cultural practice. The book examines how Minecraft players engage in a form of gameplay that is uniquely intergenerational, creative, and playful, and which moves ambivalently throughout everyday life. At the intersection of digital media, quotidian literacy, and ethnography, the book situates interdisciplinary debates around mundane play through the lens of Minecraft. Ultimately, Exploring Minecraft seeks to coalesce the discussion between formal and informal learning, fostering new forms of digital media creativity and ethnographic innovation around the analysis of games in everyday life.

Spinors in Physics (Graduate Texts in Contemporary Physics)

by Jean Hladik

Invented by Dirac in creating his relativistic quantum theory of the electron, spinors are important in quantum theory, relativity, nuclear physics, atomic and molecular physics, and condensed matter physics. Essentially, they are the mathematical entities that correspond to electrons in the same way that ordinary wave functions correspond to classical particles. Because of their relations to the rotation group SO(n) and the unitary group SU(n), this discussion will be of interest to applied mathematicians as well as physicists.

The Taxobook: Principles and Practices of Building Taxonomies, Part 2 of a 3-Part Series (Synthesis Lectures on Information Concepts, Retrieval, and Services)

by Marjorie Hlava

This book outlines the basic principles of creation and maintenance of taxonomies and thesauri. It also provides step by step instructions for building a taxonomy or thesaurus and discusses the various ways to get started on a taxonomy construction project. Often, the first step is to get management and budgetary approval, so I start this book with a discussion of reasons to embark on the taxonomy journey. From there I move on to a discussion of metadata and how taxonomies and metadata are related, and then consider how, where, and why taxonomies are used. Information architecture has its cornerstone in taxonomies and metadata. While a good discussion of information architecture is beyond the scope of this work, I do provide a brief discussion of the interrelationships among taxonomies, metadata, and information architecture. Moving on to the central focus of this book, I introduce the basics of taxonomies, including a definition of vocabulary control and why it is so important, how indexing and tagging relate to taxonomies, a few of the types of tagging, and a definition and discussion of post- and pre-coordinate indexing. After that I present the concept of a hierarchical structure for vocabularies and discuss the differences among various kinds of controlled vocabularies, such as taxonomies, thesauri, authority files, and ontologies. Once you have a green light for your project, what is the next step? Here I present a few options for the first phase of taxonomy construction and then a more detailed discussion of metadata and markup languages. I believe that it is important to understand the markup languages (SGML and XML specifically, and HTML to a lesser extent) in relation to information structure, and how taxonomies and metadata feed into that structure. After that, I present the steps required to build a taxonomy, from defining the focus, collecting and organizing terms, analyzing your vocabulary for even coverage over subject areas, filling in gaps, creating relationships between terms, and applying those terms to your content. Here I offer a cautionary note: don’t believe that your taxonomy is “done!” Regular, scheduled maintenance is an important—critical, really—component of taxonomy construction projects. After you’ve worked through the steps in this book, you will be ready to move on to integrating your taxonomy into the workflow of your organization. This is covered in Book 3 of this series.

The Taxobook: History, Theories, and Concepts of Knowledge Organization, Part 1 of a 3-Part Series (Synthesis Lectures on Information Concepts, Retrieval, and Services)

by Marjorie Hlava

This is the first volume in a series about creating and maintaining taxonomies and their practical applications, especially in search functions. In Book 1 (The Taxobook: History, Theories, and Concepts of Knowledge Organization), the author introduces the very foundations of classification, starting with the ancient Greek philosophers Plato and Aristotle, as well as Theophrastus and the Roman Pliny the Elder. They were first in a line of distinguished thinkers and philosophers to ponder the organization of the world around them and attempt to apply a structure or framework to that world. The author continues by discussing the works and theories of several other philosophers from Medieval and Renaissance times, including Saints Aquinas and Augustine, William of Occam, Andrea Cesalpino, Carl Linnaeus, and René Descartes. In the 17th, 18th, and 19th centuries, John Locke, Immanuel Kant, James Frederick Ferrier, Charles Ammi Cutter, and Melvil Dewey contributed greatly to the theories of classification systems and knowledge organization. Cutter and Dewey, especially, created systems that are still in use today. Chapter 8 covers the contributions of Shiyali Ramamrita Ranganathan, who is considered by many to be the “father of modern library science.” He created the concept of faceted vocabularies, which are widely used—even if they are not well understood—on many e-commerce websites. Following the discussions and historical review, the author has included a glossary that covers all three books of this series so that it can be referenced as you work your way through the second and third volumes. The author believes that it is important to understand the history of knowledge organization and the differing viewpoints of various philosophers—even if that understanding is only that the differing viewpoints simply exist. Knowing the differing viewpoints will help answer the fundamental questions: Why do we want to build taxonomies? How do we build them to serve multiple points of view?

The Taxobook: Applications, Implementation, and Integration in Search, Part 3 of a 3-Part Series (Synthesis Lectures on Information Concepts, Retrieval, and Services)

by Marjorie M.K. Hlava

This book is the third of a three-part series on taxonomies, and covers putting your taxonomy into use in as many ways as possible to maximize retrieval for your users. Chapter 1 suggests several items to research and consider before you start your implementation and integration process. It explores the different pieces of software that you will need for your system and what features to look for in each. Chapter 2 launches with a discussion of how taxonomy terms can be used within a workflow, connecting two—or more—taxonomies, and intelligent coordination of platforms and taxonomies. Microsoft SharePoint is a widely used and popular program, and I consider their use of taxonomies in this chapter. Following that is a discussion of taxonomies and semantic integration and then the relationship between indexing and the hierarchy of a taxonomy. Chapter 3 (“How is a Taxonomy Connected to Search?”) provides discussions and examples of putting taxonomies into use in practical applications. It discusses displaying content based on search, how taxonomy is connected to search, using a taxonomy to guide a searcher, tools for search, including search engines, crawlers and spiders, and search software, the parts of a search-capable system, and then how to assemble that search-capable system. This chapter also examines how to measure quality in search, the different kinds of search, and theories on search from several famous theoreticians—two from the 18th and 19th centuries, and two contemporary. Following that is a section on inverted files, parsing, discovery, and clustering. While you probably don’t need a comprehensive understanding of these concepts to build a solid, workable system, enough information is provided for the reader to see how they fit into the overall scheme. This chapter concludes with a look at faceted search and some possibilities for search interfaces. Chapter 4, “Implementing a Taxonomy in a Database or on a Website,” starts where many content systems really should—with the authors, or at least the people who create the content. This chapter discusses matching up various groups of related data to form connections, data visualization and text analytics, and mobile and e-commerce applications for taxonomies. Finally, Chapter 5 presents some educated guesses about the future of knowledge organization. Table of Contents: List of Figures / Preface / Acknowledgments / On Your Mark, Get Ready …. WAIT! Things to Know Before You Start the Implementation Step / Taxonomy and Thesaurus Implementation / How is a Taxonomy Connected to Search? / Implementing a Taxonomy in a Database or on a Website / What Lies Ahead for Knowledge Organization? / Glossary / End Notes / Author Biography

SOFSEM 2000: 27th Conference on Current Trends in Theory and Practice of Informatics Milovy, Czech Republic, November 25 - December 2, 2000 Proceedings (Lecture Notes in Computer Science #1963)

by Vaclav Hlavac Keith G. Jeffery Jirí Wiedermann

The international conference on current trends in the theory and practice of informatics SOFSEM 2000 was held 25 November–2 December 2000 in the c- ference facilities of the Dev?et Skal (Nine Rocks) Hotel, Milovy, Czech-Moravian Highlands, the Czech Republic. It was already the 27th annual meeting in the series of SOFSEM conferences organized in either the Czech or the Slovak Rep- lic. Since its establishment in 1974, SOFSEM has gone through a long dev- opment in parallel with the entire ?eld of informatics. Currently SOFSEM is a wide-scope, multidisciplinary conference, with stress on the interplay between the theory and practice of informatics. The SOFSEM scienti?c program consists mainly of invited talks which determine the topics of the conference. Invited talks are complemented by short refereed talks contributed by SOFSEM parti- pants. The topics of invited talks are chosen so as to cover the span from theory to practice and to bring interesting research areas to the attention of conf- ence participants. For the year 2000, the following three streams were chosen for presentation by the SOFSEM Steering Committee: – Trends in Algorithmics – Information Technologies in Practice – Computational Perception The above streams were covered through 16 invited talks given by prominent researchers. There were 18 contributed talks also presented, chosen by the int- national Program Committee from among 36 submitted papers. The program also included a panel on lessons learned from the Y2K problem.

Dependable Computing - EDDC-3: Third European Dependable Computing Conference, Prague, Czech Republic, September 15-17, 1999, Proceedings (Lecture Notes in Computer Science #1667)

by Jan Hlavicka Erik Maehle Andras Pataricza

The idea of creating the European Dependable Computing Conference (EDCC) was born at the moment when the Iron Curtain fell. A group of enthusiasts, who were pre viously involved in research and teaching in the ?eld of fault tolerant computing in different European countries, agreed that there is no longer any point in keeping pre viously independent activities apart and created a steering committee which took the responsibility for preparing the EDCC calendar and appointing the chairs for the in dividual conferences. There is no single European or global professional organization that took over the responsibility for this conference, but there are three national in terest groups that sent delegates to the steering committee and support its activities, especially by promoting the conference materials. As can be seen from these materi als, they are the SEE Working Group “Dependable Computing” (which is a successor organizationof AFCET)in France,theGI/ITG/GMATechnicalCommitteeonDepend ability and Fault Tolerance in Germany, and the AICA Working Group “Dependability of Computer Systems” in Italy. In addition, committees of several global professional organizations, such as IEEE and IFIP, support this conference. Prague has been selected as a conference venue for several reasons. It is an easily accessible location that may attract many visitors by its beauty and that has a tradition in organizing international events of this kind (one of the last FTSD conferences took place here).
