- Abstract
- Class-tested and coherent, this textbook teaches information retrieval, including web search, text classification, and text clustering from basic concepts. Ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students. Slides and additional exercises are available for lecturers. - This book provides what Salton and Van Rijsbergen both failed to achieve. Even more important, unlike some other books in IR, the authors appear to care about making the theory as accessible as possible to the reader, on occasion including short primers to certain topics or choosing to explain difficult concepts using simplified approaches. Its coverage [is] excellent, the quality of writing high and I was surprised how much I learned from reading it. I think the online resources are impressive.

- Stattdessen präferiert er in erster Näherung A. Endres' Definition, die auch von vielen Wirtschaftsinformatikern - und auch von BID-Fachleuten - akzeptiert wird: "Information, so Spitta, sind interpretierbare, d.h. mit Bedeutung verknüpfte, meist neue Nachrichten, die von einem Empfänger für das Verfolgen seiner Ziele als nützlich gewertet werden." (S. 44, Hervor. i. Org.). Damit kann sich Spitta jedoch noch nicht begnügen, da er Bezug zur Informatik, insbesondere jedoch zur Wirtschaftsinformatik oder Informationswirtschaft herstellen muss. A. Endres definiert Information als ein Tripel I = (A*, S, K), "wobei A* (...) eine Menge von Wörtern (...) über einem Alphabet A, S eine Menge von Symbolen und K einen Kontext bedeutet" (S. 45) "Information", so Spitta, wäre dann "eine Nachricht über einem definierten Alphabet und anderen Symbolen, die für den Empfänger neu und relevant ist und deren Kontext er kennt." (S. 45) In der betrieblichen Praxis sind jedoch mehrere Akteure involviert, sodass es sinnvoll ist "Datenspeicher als Puffer für Nachrichten" (S. 46) einzuführen. Nun fehlt noch eine Definition von Wissen, um betriebliche Prozesse computergestützt abzubilden. "Wissen ist wegen seiner impliziten Bestandteile ebenso individualisiert wie Information. Explizites Wissen basiert auf Daten. Implizites Wissen kann explizit gemacht werden, wenn wir über einen allgemein verstehbaren Formalismus zur Beschreibung verfügen. Der Unterschied zur Information ist die Handlungskompetenz und die mehrfache Verwendbarkeit der zur Grunde liegenden Daten, die im Allgemeinen nur einmal (individuelle) Information sein können." (S. 50, Hervor. i. Orig.) Im Kapitel 5 stehen die "Inhalte betrieblicher Daten" im Mittelpunkt, wo es unter anderem um Grunddaten (wie Sachanlagen), Vorgangsdaten (wie aufzeichnungspflichtige Vorgänge) oder abgeleitete Daten (wie Führungsinformation) geht. Das 6. Kapitel "Die Struktur betrieblicher Daten" geht auf verschiedene Datenmodelle, wie das Relationsmodell, das grafische Objektmodell oder das Vorgehensmodell zur Datenmodellierung ein. Im 7. Kapitel geht es um "Anwendungssysteme", d.h. um betriebliche Informationssysteme und deren Strukturierungsmöglichkeiten.

- Abstract
- "How to Build a Digital Library" is the only book that offers all the knowledge and tools needed to construct and maintain a digital library, regardless of the size or purpose. It is the perfectly self-contained resource for individuals, agencies, and institutions wishing to put this powerful tool to work in their burgeoning information treasuries. The second edition reflects new developments in the field as well as in the Greenstone Digital Library open source software. In Part I, the authors have added an entire new chapter on user groups, user support, collaborative browsing, user contributions, and so on. There is also new material on content-based queries, map-based queries, cross-media queries. There is an increased emphasis placed on multimedia by adding a 'digitizing' section to each major media type. A new chapter has also been added on 'internationalization', which will address Unicode standards, multi-language interfaces and collections, and issues with non-European languages (Chinese, Hindi, etc.). Part II, the software tools section, has been completely rewritten to reflect the new developments in Greenstone Digital Library Software, an internationally popular open source software tool with a comprehensive graphical facility for creating and maintaining digital libraries. As with the First Edition, a web site, implemented as a digital library, will accompany the book and provide access to color versions of all figures, two online appendices, a full-text sentence-level index, and an automatically generated glossary of acronyms and their definitions. In addition, demonstration digital library collections will be included to demonstrate particular points in the book. To access the online content please visit our associated website. This title outlines the history of libraries - both traditional and digital - and their impact on present practices and future directions. It is written for both technical and non-technical audiences and covers the entire spectrum of media, including text, images, audio, video, and related XML standards. It is web-enhanced with software documentation, color illustrations, full-text index, source code, and more.

- Abstract
- Information is essential to all human activity, and information in electronic form both amplifies and augments human information interactions. This lecture surveys some of the different classical meanings of information, focuses on the ways that electronic technologies are affecting how we think about these senses of information, and introduces an emerging sense of information that has implications for how we work, play, and interact with others. The evolutions of computers and electronic networks and people's uses and adaptations of these tools manifesting a dynamic space called cyberspace. Our traces of activity in cyberspace give rise to a new sense of information as instantaneous identity states that I term proflection of self. Proflections of self influence how others act toward us. Four classical senses of information are described as context for this new form of information. The four senses selected for inclusion here are the following: thought and memory, communication process, artifact, and energy. Human mental activity and state (thought and memory) have neurological, cognitive, and affective facets.The act of informing (communication process) is considered from the perspective of human intentionality and technical developments that have dramatically amplified human communication capabilities. Information artifacts comprise a common sense of information that gives rise to a variety of information industries. Energy is the most general sense of information and is considered from the point of view of physical, mental, and social state change. This sense includes information theory as a measurable reduction in uncertainty. This lecture emphasizes how electronic representations have blurred media boundaries and added computational behaviors that yield new forms of information interaction, which, in turn, are stored, aggregated, and mined to create profiles that represent our cyber identities.
