Abstract

"The Semantic Web is an extension of the current Web in which information is given well defined meaning, better enabling computers and people to work in cooperation." - Tim Berners Lee, "Scientific American", May 2001. This authoritative guide shows how the "Semantic Web" works technically and how businesses can utilize it to gain a competitive advantage. It explains what taxonomies and ontologies are as well as their importance in constructing the Semantic Web. The companion web site includes further updates as the framework develops and links to related sites.

Rez. Amazon: "Die Autoren bezeichnen das Buch im Vorwort als strategischen Führer für Führungskräfte und Entwickler die sich einen Überblick über das Semantic Web und die dahinter stehende Vision machen wollen. Genau diesem Anspruch wird das Buch auch absolut gerecht. Die ersten beiden Kapitel beschreiben die Vision sowie die Möglichkeiten, die sich durch den Einsatz der in den nachfolgenden Kapiteln beschriebenen Techniken bieten. Die Autoren schaffen es anhand vieler praktischer Szenarien (die zwar teilweise meiner Einschätzung nach schon noch in einiger Zukunft liegen, aber die große Vision des ganzen schön vergegenwärtigen) sehr schnell den Leser für die Technik zu begeistern und mehr darüber wissen zu wollen. Die nachfolgenden Kapitel beschreiben die Techniken auf den verschiedenen semantischen Ebenen von XML als Basis für alles weitere, über Web Services, RDF, Taxonomies und Ontologies. Den Autoren gelingt es die beschriebenen Techniken so kurz und prägnant zu erklären, dass sich der Leser danach zumindest ein Bild über die Techniken an sich, sowie über deren komplexes Zusammenspiel machen kann. Auch für Entwickler würde ich das Buch empfehlen, da es einen sehr guten Einstieg in viele doch sehr neue Techniken bietet mit vielen Verweisen auf weitere Literatur. Alles in allem ein sehr gelungenes Buch, das es trotz relativ geringem Umfangs schafft, einen guten Überblick über dieses komplexe Thema zu vermitteln."

The concluding chapter addresses the future of KM. Liebowitz asserts that knowledge management will not become a discipline in its own right but that its practices will continue to integrate with other fields such as organizational learning and computer science. He envisions LIS professionals as brokers making connections between the people of an organization and the knowledge it creates, with the library or information center as the middle ground between codification and personalization. In that vision, he sees a role for LIS professionals in pushing information to employees rather than taking the more traditional role of reacting to information requests. He sees a future in which LIS professionals take leadership roles in KM programs through the integration of their technological, organizational, and human interaction skills. He is hopeful that in time libraries will take ownership of KM programs within organizations. His statement, "The library has always been a treasure house of information, and it needs to continue to expand into the knowledge chest as well" (p. 33) expresses Liehowitz's charge to corporate and government LIS professionals. The ideas presented in What They Didn't Tell You about Knowledge Management are certainly in support of that charge.' This work provides a broad overview of the KM field and serves as an initial source for exploration for LIS professionals working in a corporate setting or considering doing so."

Abstract

Information management (IM) has exploded in importance in recent years and yet until now there has been no Reader to introduce students to the subject. This comprehensive international collection introduces you to the core topics and methodologies used in teaching IM, namely: information behaviour; environmental scanning and decision making; knowledge management; and information strategy. These peer-reviewed papers represent an elite selection from the respected "Information Research" journal, each carefully updated to take into account recent developments. This book is an essential introduction to IM for all students on courses in library and information science, IM, information systems, business information technology, business management, computer science and information technology; as well as for practitioners working in a wide range of organizations providing information services.

Allen strikes a realistic note of the institutional importance of trust across teams of academics and administrators, and subsequently of the political behavior of academics and computer services administrators/ managers and the relation of the latter to information strategy formulation. Research was conducted at 12 university sites, information strategy process documents were analyzed, and 20 informants were interviewed at each site. The study's research focused on cross-case analysis (instead of an iterative approach to collection and analysis of data), research was longitudinal, and a grounded theory approach was employed. According to the author, findings confirm a similar position taken by Pettigrew (1977): "development of information strategy is the outcome of negotiated political relations" (p. 177). And for such negotiated political relations, the author concludes, trust is a necessary ingredient. It is important to reiterate that IM's scope requires a diversity of study methods and methodologies to address all issues involved. A multiplicity of information and IM definitions and the number of local and global issues that must be addressed, along with information's significance as resource and/or commodity in different types of organizations, necessitate diversity in information research. Each chapter has demonstrated a need to cover many aspects of IM and to ensure that there is as much clarity in that effort as possible, and yet differentiation of IM from other related fields such as KM clearly remains a top issue. As with any other effort to define a field's boundaries, the task at hand is not easy, but while definitions and boundaries are being worked out, there is always an opportunity to engage in fruitful discussions about scope and critical issues in information research."

Abstract

Das wachsende Informationsvolumen im WWW führt paradoxerweise zu einer immer schwierigeren Nutzung, das Finden und Verknüpfen von Informationen in einem unstrukturierten Umfeld wird zur Sisyphosarbeit. Hier versprechen Semantic-Web-Ansätze Abhilfe. Die Autoren beschreiben Technologien, wie eine semantische Integration verteilter Daten durch verteilte Ontologien erreicht werden kann. Diese Techniken sind sowohl für Forscher als auch für Professionals interessant, die z.B. die Integration von Produktdaten aus verteilten Datenbanken im WWW oder von lose miteinander verbunden Anwendungen in verteilten Organisationen implementieren sollen.

Rez. in: KO 34(2007) no.4, S.266-267 (E. Quintarelli): "The knowledge and information world we live in can rarely be described from a single coherent and predictable point of view. In the global economy and mass society, an explosion of knowledge sources, different paradigms and information-seeking behaviors, fruition contexts and access devices are overloading our existence with an incredible amount of signals and stimulations, all competing for our limited attention. Taxonomies are often cited as tools to cope with, organize and make sense of this complex and ambiguous environment. Leveraging an extensive review of literature from a variety of disciplines, as well as a wide range of relevant real-life case studies, Organising Knowledge by Patrick Lambe has the great merit of liberating taxonomies from their recurring obscure and limitative definition, making them living, evolving and working tools to manage knowledge within organizations. Primarily written for knowledge and information managers, this book can help a much larger audience of practitioners and students who wish to design, develop and maintain taxonomies for large-scale coordination and organizational effectiveness both within and across societies. Patrick Lambe opens ours eyes to the fact that, far from being just a synonym for pure hierarchical trees to improve navigation, find-ability and information retrieval, taxonomies take multiple forms (from lists, to trees, facets and system maps) and play different roles, ranging from basic information organization to more subtle tasks, such as establishing common ground, overcoming boundaries, discovering new opportunities and helping in sense-making.
While each single paragraph of the book is packed with valuable advice and real-life experience, I consider the last chapter to be the most intriguing and ground-breaking one. It's only here that taxonomists meet folksonomists and ontologists in a fundamental attempt to write a new page on the relative position between old and emerging classification techniques. In a well-balanced and sober analysis that foregoes excessive enthusiasm in favor of more appropriate considerations about content scale, domain maturity, precision and cost, knowledge infrastructure tools are all arrayed from inexpensive and expressive folksonomies on one side, to the smart, formal, machine-readable but expensive world of ontologies on the other. In light of so many different tools, information infrastructure clearly appears more as a complex dynamic ecosystem than a static overly designed environment. Such a variety of tasks, perspectives, work activities and paradigms calls for a resilient, adaptive and flexible knowledge environment with a minimum of standardization and uniformity. The right mix of tools and approaches can only be determined case by case, by carefully considering the particular objectives and requirements of the organization while aiming to maximize its overall performance and effectiveness. Starting from the history of taxonomy-building and ending with the emerging trends in Web technologies, artificial intelligence and social computing, Organising Knowledge is thus both a guiding tool and inspirational reading, not only about taxonomies, but also about effectiveness, collaboration and finding middle ground: exactly the right principles to make your intranet, portal or document management tool a rich, evolving and long-lasting ecosystem."

Abstract

-Existing classification systems serve interdisciplinary research and teaching poorly. -A novel approach to classification, grounded in the phenomena studied rather than disciplines, would serve interdisciplinary scholarship much better. It would also have advantages for disciplinary scholarship. The productivity of scholarship would thus be increased. -This novel approach is entirely feasible. Various concerns that might be raised can each be addressed. The broad outlines of what a new classification would look like are developed. -This new approach might serve as a complement to or a substitute for existing classification systems. -Domain analysis can and should be employed in the pursuit of a general classification. This will be particularly important with respect to interdisciplinary domains. -Though the impetus for this novel approach comes from interdisciplinarity, it is also better suited to the needs of the Semantic Web, and a digital environment more generally. Though the primary focus of the book is on classification systems, most chapters also address how the analysis could be extended to thesauri and ontologies. The possibility of a universal thesaurus is explored. The classification proposed has many of the advantages sought in ontologies for the Semantic Web. The book is therefore of interest to scholars working in these areas as well.

Abstract

The Nobel prize-winning author of "A Different Universe" argues that ours is an age of disinformation and ignorance, in which access to knowledge is becoming increasingly restricted and even criminalized. We like to believe that in our modern, technologically advanced world, information is more freely available and flows faster than ever before, and that this free flow of ideas is behind our remarkable creativity. The second part is right: the free flow of ideas is indeed essential to creativity. But according to Nobel Laureate Robert Laughlin, many forces in the modern world conspire to make acquiring information a danger or even a crime. More and more of the really valuable information is private property or a state secret, with the result being that it is now easy for a flash of insight, entirely innocently, to infringe a patent or threaten national security.Within the past ten years it has become illegal to circumvent anti-piracy measures (i.e. to understand encrypted communication) or to distribute code-cracking devices; it is now legal for corporations to monopolize certain forms of communication; and it is possible to patent sales techniques, hiring strategies, and gene sequences. Broad areas of two sciences, physics and biology, are now off limits to public discourse because they are national security risks. Our society is sequestering knowledge more rapidly and thoroughly than any before it.Thus we find ourselves dealing more and more with the bizarre concept of the Crime of Reason, the antisocial and sometimes outright illegal nature of certain intellectual activities. The increasing restrictions on such fertile scientific and technological fields as cryptography, biotechnology, and computer software design are creating a new Dark Age: a time characterized not by light and truth but by disinformation and ignorance. This short, passionately argued book, by a Nobel laureate in physics, offers a stern warning and protest against our apparent collective decision to relinquish our intellectual rights.

Rez. in: iwp 64(2013) H.4, S.232-233 (W. Löw): "Der verdienstvolle Vorsatz Neusers durch begriffstheoretische Untersuchung einen Wissensbegriff zu entwickeln, der einen neuen Schlüssel zum Verständnis ideengeschichtlicher Epochen und kultureller Traditionen bietet, erreicht mich leider nicht. Ich kann auch nur soweit folgen, dass Wissen ein sich selbst organisierendes und stabilisierendes System ist. Dass aber der Mensch seine Mittelpunktstellung als denkendes Subjekt verloren hat, darf bestritten werden (auch wenn manche Alltagserfahrung dem Autor und nicht mir Recht gibt). Oder will der Autor dem alten, ironisch gemeinten Buchtitel von Weizenbaum "Die Macht der Computer und die Ohnmacht der Vernunft" (dt. Suhrkamp, 1978) doch weiter zum Durchbruch verhelfen? Immerhin sagt Neuser, was von den menschlichen Akteuren bleibe, sei das Individuum, welches sein individuelles Wissen aus der Interaktion mit Allgemeinwissen bezieht. Diesbezüglich hat Weizenbaum einmal zu mir gesagt, dass das Beste das eigene Denken ist. Vielleicht ein Rat für eine Nachauflage, den außerordentlich interdisziplinär denkenden Joseph Weizenbaum in die ansonsten beachtliche Bibliographie mit aufzunehmen. Sie wird auch ein Grund dafür sein, dass das Buch einen Platz in meinem Bücherschrank finden wird." 2017 in einer 2. Aufl. erschienen.

Abstract

Looking at knowledge as a shared resource: experts discuss how to define, protect, and build the knowledge commons in the digital age. Knowledge in digital form offers unprecedented access to information through the Internet but, at the same time, is subject to ever-greater restrictions through intellectual property legislation, overpatenting, licensing, overpricing, and lack of preservation. Looking at knowledge as a commons - as a shared resource - allows us to understand both its limitless possibilities and what threatens it. In "Understanding Knowledge as a Commons", experts from a range of disciplines discuss the knowledge commons in the digital era - how to conceptualize it, protect it, and build it. Contributors consider the concept of the commons historically and offer an analytical framework for understanding knowledge as a shared social-ecological system. They look at ways to guard against enclosure of the knowledge commons, considering, among other topics, the role of research libraries, the advantages of making scholarly material available outside the academy, and the problem of disappearing Web pages. They discuss the role of intellectual property in a new knowledge commons, the open access movement (including possible funding models for scholarly publications), the development of associational commons, the application of a free/open source framework to scientific knowledge, and the effect on scholarly communication of collaborative communities within academia, and offer a case study of EconPort, an open access, open source digital library for students and researchers in microeconomics. The essays clarify critical issues that arise within these new types of commons - and offer guideposts for future theory and practice.
