Abstract

Dieser Beitrag beschäftigt sich mit INSYDER, einem visuell unterstützten Suchsystem im Umfeld der sogenannten Business Intelligence Systeme. Dabei liegt der Schwerpunkt dieses Beitrags in der Erläuterung der Information Retrieval- und Visualisierungsaspekte zur Unterstützung des Suchprozesses im WWW. Vorgestellt wird das Rankingverfahren, das Interaktive Relevance Feedback sowie die Beschreibung der Unterstützung des Benutzers bei der Formulierung der Suchanfrage mittels Visualisierung.

Content

This paper presents a visual information seeking system for the WWW called INSYDER. The aim of INSYDER is to find business information from the WWW. Information seeking - especially on the Web - is an imprecise process. Information seekers often have only a fuzzy understanding of how they can get the information they want. This paper focuses on the use of information retrieval and visualisation techniques of the INSYDER system to support the user in extracting information from the WWW, namely in formulating queries, refining and reviewing results

Abstract

Information systems are essential support for knowledge management in all types of enterprises. This paper describes the evolution and development of a specialized hospital information system. The system is designed to integrate for access and retrieval from databases of patients' case records, and related images - CATSCAN, MRI, X-Ray - and to enable online access to full text of relevant papers on the Internet/WWW. The generation of information products and services from the system is briefly described.

Abstract

The explosion of the Internet and information technology in general has created challenges and opportunities for information professionals that are redefining their role. Information professionals now interact with different groups within an organization, such as the Management Information System (MIS) staff and must have the ability to work effectively with MIS as a team to make the content of the system readily available. To do this they must keep up with the latest technologies related to text retrieval, content organization, search technologies, and knowledge management. Explores the opportunities for information professionals to expand their role with these new technologies and with MIS. Discusses metadata, search engines, and information retrieval agents and provides a glossary of buzzwords and a list of Web sites for additional information

Abstract

This paper proposes a framework for analyzing management processes of inter-firm competence. Effective and efficient management of inter-firm competence is suggested to depend an a balance between knowledge systems and enabling information technologies. Knowledge processes comprise processes to collect, generate, diffuse, utilize and dispose knowledge. Managing these processes in an inter-firm environment poses some new challenges both to knowledge and information system development as well.

Abstract

The MEMOIR project supports researchers working with a vast quantity of distributed information, by assisting them in finding both relevant documents and researchers with related interests. It is an open architecture based on the existing Web infrastructure. Key to the architecture is the use of proxies: to support message routing for dynamic reconfiguration and extension of the system, to collect information about the trail of documents that a user visits, and to insert links on the fly. Presents the MEMOIR framework and its rationale, and discusses early experiences with the system

Abstract

Der Prozeß einer Erfassung und Modellierung von Informationsbedürfnissen in Wirtschaftsunternehmen oder Verwaltungen gestaltet sich nach derzeitigem Verständnis in sequentiell abzuarbeitenden Phasen. Danach sind zunächst die Anforderungen an ein Informationssystem festzustellen, aus dem sich die unternehmensweit benötigten Informationskategorien ableiten, das sog. Datenmodell. Dieses besteht aus einer Klassifizierung real interessierender betrieblicher Objekte und ihrer Beziehungen

Abstract

Until the 1980s, the handling of documentary information in business was usually split up among 4 unrelated independent departments: the library; archives; secretarial services; and reproduction/printing. The introduction of new technology allows the integration of these operations into a single system; comprising subsystems for: production of internal documents; acquisition and storage of external documents; information retrieval; archive creation and maintenance; and circulation of information between departments, based on local computer networks. In reality, not many businesses are making use of technology available to set up such integrated systems because of the lack of common standards for equipment and software, which makes internal and external communication unreliable. This problem may be resolved in the near future, as a result of discussions now in progress at international level.

Abstract

Interorganizational knowledge creation has become a crucial factor for successful management of corporations in the environment surrounding them today. Collaboration with other organizations is indispensable for a corporation to resolve complex and Jong range issues such as customer satisfaction and sustainable development. One of the most fundamental obstacles in creating knowledge among organizations is partial or incomplete communication due to incommensurable point of view. Policy exercises can improve commensurability and facilitate inter-organizational knowledge creation by providing a shared model of the system under investigation. This paper will discuss it taking Intelligent Transportation System (TTS) Deployment Exercises as an example.

Abstract

The rationale and the general outline of a system for the management of collective knowledge (CKMS) has been presented by Poitou at ISMICK 95. The features of a CKMS are quite closely implemented in DIADEME, a computer assisted system for the capitalization and the management of research engineers' knowledge, which has been designed, developed and is currently being implemented at Electricité de France (EDF) by Ballay. During Spring 1995, Poitou has conducted at EDF a survey of the engineers' knowledge management behavior, of their attitudes toward a prospective CKMS. During Spring 1996, Poitou conducted a survey among the same engineers about their users' reactions to the implementation of DIADEME. The present paper briefly sums up the main features of a CKMS, (Section 1) describes the aims and the general architecture of DIADEME (Section 4), and gives some insight into the results of the 1995 users' expectation survey (Section 3) and of the 1996 users' satisfaction survey (Section 5).

Abstract

Introduces a knowledge management oriented view of decisions and decisioning as a complement to classical perspectives and as a contribution to understanding computer based possibilities for relaxing strains on decision makers. The perspective includes a model of knowledge management activities performed by a decision maker and a taxonomy of knowledge types. This leads to a characterization of decision support system purposes, traits and potentials that offer a basis for new research into computerized possibilities for knowledge management

Rez. in: nfd - Information 54(2003) H.6, S.378-379 (T. Mandl): "Im Oktober 2001 fand erstmals eine Tagung mit dem Titel "Web Intelligence" statt. Ist dies nun eine neue Disziplin oder der Versuch analog zu "Artificial Intelligence" und "Computational Intelligence" ein neues Modewort zu kreieren? Geht es um den Einsatz sogenannter intelligenter Verfahren, um mit dem Internet umgehen zu können oder erscheint das Internet als "emerging global brain" (Goertzel 2002), also als eine unerschöpfliche Quelle von Wissen, die nur geschickt ausgebeutet werden muss? Kommt also die Intelligenz aus dem Web oder dient die Intelligenz als Werkzeug für das Web? Der Tagungsband ist seit Anfang 2003 verfügbar und bietet nun den Anlass, diesen Begriff anhand der darin präsentierten Inhalte zu bewerten. Die Herausgeber führen in ihrem einleitenden Artikel gleich die Abkürzung WI ein und versuchen tatsächlich "Web Intelligence" als neue Sub-Disziplin der Informatik zu etablieren. Zu diesem Zweck greifen sie auch auf die Anzahl der Nachweise für diese Phrase in Suchmaschinen zu. Zwar lieferten die Systeme angeblich Zahlen von über einer Million (S. 4), aber dies überzeugt sicher noch niemanden, das Studium der WI aufzunehmen. Allerdings weist dieses Vorgehen schon auf einen Kern der WI hin: man versucht, aus dem im Web gespeicherten Wissen neues Wissen zu generieren. Damit wäre man sehr nahe am Data oder eben Web-Mining, jedoch geht die Definition der Autoren darüber hinaus. Sie wollen WI verstanden wissen als die Anwendung von Künstlicher Intelligenz sowie Informationstechnologie im Internet (S. 2). Da nun Künstliche Intelligenz bei allen Meinungsverschiedenheiten sicherlich nicht ohne Informationstechnologie denkbar ist, wirkt die Definition nicht ganz überzeugend. Allerdings beschwichtigen die Autoren im gleichen Atemzug und versichern, diese Definition solle ohnehin keine Forschungsrichtung ausschließen. Somit bietet sich eher eine Umfangsdefinition an. Diese solle die wichtigsten Stoßrichtungen des Buchs und damit auch der Tagung umfassen. Als Ausgangspunkt dient dazu auch eine Liste der Herausgeber (S. 7f.), die hier aber etwas modifiziert wird: - Grundlagen von Web Informationssystemen (Protokolle, Technologien, Standards) - Web Information Retrieval, WebMining und Farming - Informationsmanagement unter WebBedingungen - Mensch-Maschine Interaktion unter Web-Bedingungen (hier "HumanMedia Engineering" S. XII) Eine grobe Einteilung wie diese ist zwar übersichtlich, führt aber zwangsläufig zu Ouerschnittsthemen. In diesem Fall zählt dazu das Semantic Web, an dem momentan sehr intensiv geforscht wird. Das Semantic Web will das Unbehagen mit der Anarchie im Netz und daraus folgenden Problemen für die Suchmaschinen überwinden, indem das gesamte Wissen im Web auch explizit als solches gekennzeichnet wird. Tauchen auf einer WebSeite zwei Namen auf und einer ist der des Autors und der andere der eines Sponsors, so erlauben neue Technologien, diese auch als solche zu bezeichnen. Noch wichtiger, wie in einer Datenbank sollen nun Abfragen möglich sein, welche andere Seiten aus dem Web liefen, die z.B. den gleichen Sponsor, aber einen anderen Autor haben. Dieser Thematik widmen sich etwa Hendler & Feigenbaum. Das Semantic Web stellt ein Ouerschnittsthema dar, da dafür neue Technologien (Mizoguchi) und ein neuartiges Informationsmanagement erforderlich sind (z.B. Stuckenschmidt & van Harmelen), die Suchverfahren angepasst werden und natürlich auch auf die Benutzer neue Herausforderungen zukommen. Diesem Aspekt, inwieweit Benutzer solche Anfragen überhaupt stellen werden, widmet sich in diesem Band übrigens niemand ernsthaft. Im Folgenden sollen die einzelnen Themengebiete anhand der im Band enthaltenen Inhalte näher bestimmt werden, bevor abschließend der Versuch eines Resümees erfolgt.
- Grundlagen von Web Informationssystemen Protokolle, Technologien und Standards existieren inzwischen mannigfaltig und lediglich für spezifische Anwendungen entstehen weitere Grundlagen. In dem vorliegenden Band gibt es etwa ein Datenmodell für XML-Datenbanken (Wuwongse et al.) und den Vorschlag einer 3DModellierung (Hwang, Lee & Hwang). Auch für Proxy-Server werden neue Algorithmen entwickelt (Aguilar & Leiss). - Web Information Retrieval, WebMining und Farming Neben klassischen Themen des Information Retrieval wie kontrolliertem Vokabular (Sim & Wong), Ranking (Wang & Maguire), Kategorisierung (Loia & Luongo) und Term-Erweiterung (Huang, Oyang & Chien) stehen auch typische Web Information Retrieval Themen. Multimedia Retrieval spielt eine wichtige Rolle im Web und dazu gibt es Beiträge zu Audio (Wieczorkowska & Ra- Wan, Liu & Wang) und Grafiken (Fukumoto & Cho, Hwang, Lee & Hwang). Das Hype-Thema Link-Analyse schlägt auch gleich den Bogen hin zum Web-Mining, ist mit fünf Beiträgen aber eher unterrepräsentiert. Link-Analyse stellt die Frage, was sich aus den inzwischen wohl über zehn Milliarden Links im Internet folgern lässt. So extrahieren zwei Beiträge die zeitliche Veränderung sozialer Strukturen in Web Communities. Matsumura et al. untersuchen, ob Außenseiter sich auch für die innerhalb einer Community diskutierten Themen interessieren und werten dies als Maß für die Verbreitung des Themas. Bun & Ishizuka interessieren sich nur für die Änderungen innerhalb einer Gruppe von thematisch zusammengehörigen Web-Abgeboten und analysieren in diesem Korpus die wichtigsten Sätze, die neu entstehende Themen am besten repräsentieren. Andere Mining-Beiträge befassen sich mit der Erstellung von Sprachressourcen (Chau & Yeh). - Informationsmanagement unter WebBedingungen Für das Informationsmanagement gelten Ontologien zur Beschreibung des vorhandenen Wissens als wichtiges Instrument und dementsprechend ist "Ontologie" auch ein Kandidat für das höchst-frequente Wort in dem Tagungsband.
