    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.

    Abstract
    Wissen ist die zentrale Ressource von Unternehmen, welche Mitarbeiter benötigen, um innovative Produkte und Dienstleistungen entwickeln zu können. Dokumentiertes Wissen, wie Patente, Strategiemodelle, Best Practices oder Benchmark-Beschreibungen, lässt sich effizient in digitaler Form speichern und über digitale Netze austauschen. Derartige Wissenswerte können so innerhalb und zwischen Unternehmen über elektronische Märkte gehandelt werden. Wolfgang Maass entwickelt das Konzept eines digitalen Wissensgutes, integriert es in ein Referenzmodell für elektronische Wissensmärkte und stellt technische Umsetzungsmöglichkeiten vor.

    Rez. in: JASIST 54(2003) no.9, S.905-906 (C.A. Badurek): "Visual approaches for knowledge discovery in very large databases are a prime research need for information scientists focused an extracting meaningful information from the ever growing stores of data from a variety of domains, including business, the geosciences, and satellite and medical imagery. This work presents a summary of research efforts in the fields of data mining, knowledge discovery, and data visualization with the goal of aiding the integration of research approaches and techniques from these major fields. The editors, leading computer scientists from academia and industry, present a collection of 32 papers from contributors who are incorporating visualization and data mining techniques through academic research as well application development in industry and government agencies. Information Visualization focuses upon techniques to enhance the natural abilities of humans to visually understand data, in particular, large-scale data sets. It is primarily concerned with developing interactive graphical representations to enable users to more intuitively make sense of multidimensional data as part of the data exploration process. It includes research from computer science, psychology, human-computer interaction, statistics, and information science. Knowledge Discovery in Databases (KDD) most often refers to the process of mining databases for previously unknown patterns and trends in data. Data mining refers to the particular computational methods or algorithms used in this process. The data mining research field is most related to computational advances in database theory, artificial intelligence and machine learning. This work compiles research summaries from these main research areas in order to provide "a reference work containing the collection of thoughts and ideas of noted researchers from the fields of data mining and data visualization" (p. 8). It addresses these areas in three main sections: the first an data visualization, the second an KDD and model visualization, and the last an using visualization in the knowledge discovery process. The seven chapters of Part One focus upon methodologies and successful techniques from the field of Data Visualization. Hoffman and Grinstein (Chapter 2) give a particularly good overview of the field of data visualization and its potential application to data mining. An introduction to the terminology of data visualization, relation to perceptual and cognitive science, and discussion of the major visualization display techniques are presented. Discussion and illustration explain the usefulness and proper context of such data visualization techniques as scatter plots, 2D and 3D isosurfaces, glyphs, parallel coordinates, and radial coordinate visualizations. Remaining chapters present the need for standardization of visualization methods, discussion of user requirements in the development of tools, and examples of using information visualization in addressing research problems.
    In 13 chapters, Part Two provides an introduction to KDD, an overview of data mining techniques, and examples of the usefulness of data model visualizations. The importance of visualization throughout the KDD process is stressed in many of the chapters. In particular, the need for measures of visualization effectiveness, benchmarking for identifying best practices, and the use of standardized sample data sets is convincingly presented. Many of the important data mining approaches are discussed in this complementary context. Cluster and outlier detection, classification techniques, and rule discovery algorithms are presented as the basic techniques common to the KDD process. The potential effectiveness of using visualization in the data modeling process are illustrated in chapters focused an using visualization for helping users understand the KDD process, ask questions and form hypotheses about their data, and evaluate the accuracy and veracity of their results. The 11 chapters of Part Three provide an overview of the KDD process and successful approaches to integrating KDD, data mining, and visualization in complementary domains. Rhodes (Chapter 21) begins this section with an excellent overview of the relation between the KDD process and data mining techniques. He states that the "primary goals of data mining are to describe the existing data and to predict the behavior or characteristics of future data of the same type" (p. 281). These goals are met by data mining tasks such as classification, regression, clustering, summarization, dependency modeling, and change or deviation detection. Subsequent chapters demonstrate how visualization can aid users in the interactive process of knowledge discovery by graphically representing the results from these iterative tasks. Finally, examples of the usefulness of integrating visualization and data mining tools in the domain of business, imagery and text mining, and massive data sets are provided. This text concludes with a thorough and useful 17-page index and lengthy yet integrating 17-page summary of the academic and industrial backgrounds of the contributing authors. A 16-page set of color inserts provide a better representation of the visualizations discussed, and a URL provided suggests that readers may view all the book's figures in color on-line, although as of this submission date it only provides access to a summary of the book and its contents. The overall contribution of this work is its focus an bridging two distinct areas of research, making it a valuable addition to the Morgan Kaufmann Series in Database Management Systems. The editors of this text have met their main goal of providing the first textbook integrating knowledge discovery, data mining, and visualization. Although it contributes greatly to our under- standing of the development and current state of the field, a major weakness of this text is that there is no concluding chapter to discuss the contributions of the sum of these contributed papers or give direction to possible future areas of research. "Integration of expertise between two different disciplines is a difficult process of communication and reeducation. Integrating data mining and visualization is particularly complex because each of these fields in itself must draw an a wide range of research experience" (p. 300). Although this work contributes to the crossdisciplinary communication needed to advance visualization in KDD, a more formal call for an interdisciplinary research agenda in a concluding chapter would have provided a more satisfying conclusion to a very good introductory text.
    With contributors almost exclusively from the computer science field, the intended audience of this work is heavily slanted towards a computer science perspective. However, it is highly readable and provides introductory material that would be useful to information scientists from a variety of domains. Yet, much interesting work in information visualization from other fields could have been included giving the work more of an interdisciplinary perspective to complement their goals of integrating work in this area. Unfortunately, many of the application chapters are these, shallow, and lack complementary illustrations of visualization techniques or user interfaces used. However, they do provide insight into the many applications being developed in this rapidly expanding field. The authors have successfully put together a highly useful reference text for the data mining and information visualization communities. Those interested in a good introduction and overview of complementary research areas in these fields will be satisfied with this collection of papers. The focus upon integrating data visualization with data mining complements texts in each of these fields, such as Advances in Knowledge Discovery and Data Mining (Fayyad et al., MIT Press) and Readings in Information Visualization: Using Vision to Think (Card et. al., Morgan Kauffman). This unique work is a good starting point for future interaction between researchers in the fields of data visualization and data mining and makes a good accompaniment for a course focused an integrating these areas or to the main reference texts in these fields."

    Abstract
    Social Software Anwendungen wie Wikis, Weblogs oder Social-Networking-Plattformen sind ein integraler Bestandteil der Weiterentwicklungen des Internets. Zur Nutzung kommen diese Anwendungen aus dem Bedürfnis heraus, Wissen zu sammeln, bereitzustellen und zu verteilen bzw. Communities aufzubauen und ihnen Raum zum Austausch zu geben. Worin liegt nun aber der Nutzen des Web 2.0 für Unternehmen? Im Rahmen dieses Buches werden von rund 30 Autoren aus Wissenschaft und Praxis vier große Themenbereiche behandelt, um sich der Beantwortung dieser Frage zu nähern.Im Einführungsteil werden die Grundlagen gelegt und unterschiedliche Social-Software-Anwendungen wie Wikis, Weblogs oder Social Bookmarking erläutert. Im darauf folgenden Abschnitt rücken die Potenziale der Anwendung in Unternehmen und die Wissensarbeiter als Nutzer in den Fokus. Welche Unternehmenskultur und Kompetenzen sind notwendig, um effizient mit Social Software im Unternehmen arbeiten zu können? Wie wird Social Software im Unternehmen eingeführt?Der dritte Teil des Buches befasst sich mit konkreten Anwendungsfällen in Unternehmen. Fallstudien aus großen und kleinen Unternehmen wie z.B. IBM, Deutsche Bahn, Opel, SUN Microsystems und der PSI AG veranschaulicht. Im abschließenden Teil werden zukünftige Entwicklungen ausgelotet und Visionen gewagt.

    Rez. in: IWP 60(1009) H.4, S.245-246 (C. Wolff): "Der von Andrea Back (St. Gallen), Norbert Gronau (Potsdam) und Klaus Tochtermann herausgegebene Sammelband "Web 2.0 in der Unternehmenspraxis" verbindet in schlüssiger Weise die systematische Einführung in die Themen Web 2.0 und social software mit der Darstellung von Möglichkeiten, solche neuen Informationssysteme für Veränderungen im Unternehmen zu nutzen und zeigt dies anhand einer ganzen Reihe einzelner Fallstudien auf. Auch zukünftige Anwendungen wie das social semantic web werden als Entwicklungschance erörtert. In einer knappen Einleitung werden kurz die wesentlichen Begriffe wie Web 2.0, social software oder "Enterprise 2.0" eingeführt und der Aufbau des Bandes wird erläutert. Das sehr viel umfangreichere zweite Kapitel führt in die wesentlichen Systemtypen der social software ein: Erläutert werden Wikis, Weblogs, Social Bookmarking, Social Tagging, Podcasting, Newsfeeds, Communities und soziale Netzwerke sowie die technischen Besonderheiten von social software. Die Aufteilung ist überzeugend, für jeden Systemtyp werden nicht nur wesentliche Funktionen, sondern auch typische Anwendungen und insbesondere das Potenzial zur Nutzung im Unternehmen, insbesondere mit Blick auf Fragen des Wissensmanagements erläutert. Teilweise können die Autoren auch aktuelle Nutzungsdaten der Systeme ergänzen. Auch wenn bei der hohen Entwicklungsdynamik der social software-Systeme ständig neue Formen an Bedeutung gewinnen, vermag die Einteilung der Autoren zu überzeugen.
    Illustrieren die Fallstudien den aktuellen state-of-the-art vor allem großer Unernehmen, so geht das fünfte und abschließende Kapitel unter der Überschrift "Visionen und Trends" auf zukünftige Entwicklungen ein. Dabei stellen die Autoren zunächst das Verfahren der (Netzwerkanalyse vor, die einen Beitrag zum Verständnis von Struktur, Entwicklungsdynamik und Nutzung großer sozialer Netzwerke liefern kann, und schildern dann am praktischen Beispiel einer Großbäckerei den Ansatz einer living corporate landscape (Unternehmenslandkarte 2.0). Bei beiden Beispielen steht aber weniger der Einsatz von social software an sich im Vordergrund, sondern eher der Einsatz innovativer (Daten-)analytischer Verfahren und Repräsentationen, ggf. mit Bezug zu bestehenden social software-Anwendungen. Insofern wird deutlich, dass sich social software mit anderen Anwendungen im Bereich business intelligence koppeln lässt und so ein Mehrwert für die Unternehmen erzeugt werden kann. Zu den weiteren Technologien, die zukünftig social software-Anwendungen ergänzen können, zählen die Autoren virtuelle Welten und das semantic web, wodurch auch die Bandbreite künftiger Technologiekoppelungen im Umfeld der social software deutlich wird. Ein Glossar und ein sehr ausführliches Literaturverzeichnis runden den Band ab. Den Autoren gelingt es, anhand einer Vielzahl von Einzelstudien den aktuellen Stand des Einsatzes von Web 2.0-Anwendungen im Unternehmen darzustellen. Dass dabei tendenziell Großunternehmen im Mittelpunkt stehen, kann kaum verwundern, da anzunehmen ist, dass diese eher die Ressourcen verfügbaren haben, um solche Lösungen umzusetzen - und gleichzeitig mit der Unternehmensgröße auch die Dringlichkeit von Wissensmanagement-Maßnahmen wächst. Ungeachtet dieser Tatsache dürfte der Band aber gerade auch für kleinere Unternehmen oder Institutionen von Interesse sein, die aus den konkreten Erfahrungen, die in den Fallstudien geschildert werden, lernen wollen und sich dies für eigene Vorhaben zu Nutze machen wollen. Dabei ist der Band allerdings weniger ein Vademecum für die konkrete Umsetzung eines Web 2.0-Projektes, sondern dient der Einarbeitung in die heterogene Szenerie des derzeitigen Web 2.0-Einsatzes."

    Abstract
    A new, thoroughly updated edition of a comprehensive overview of knowledge management (KM), covering theoretical foundations, the KM process, tools, and professions. The ability to manage knowledge has become increasingly important in today's knowledge economy. Knowledge is considered a valuable commodity, embedded in products and in the tacit knowledge of highly mobile individual employees. Knowledge management (KM) represents a deliberate and systematic approach to cultivating and sharing an organization's knowledge base. This textbook and professional reference offers a comprehensive overview of the field. Drawing on ideas, tools, and techniques from such disciplines as sociology, cognitive science, organizational behavior, and information science, it describes KM theory and practice at the individual, community, and organizational levels. Chapters cover such topics as tacit and explicit knowledge, theoretical modeling of KM, the KM cycle from knowledge capture to knowledge use, KM tools, KM assessment, and KM professionals.
