- Abstract
- Conceptual Knowledge Markup Language (CKML), an application of XML, is a new standard being promoted for the specification of online conceptual knowledge (Kent and Shrivastava, 1998). CKML follows the philosophy of Conceptual Knowledge Processing (Wille, 1982), a principled approach to knowledge representation and data analysis, which advocates the development of methodologies and techniques to support people in their rational thinking, judgement and actions. CKML was developed and is being used in the WAVE networked information discovery and retrieval system (Kent and Neuss, 1994) as a standard for the specification of conceptual knowledge

- Rez. in: nfd 54(2003) H.8, S.497 (T. Mandl): "Gesetze der digitalen Anarchie - Hyperlinks im Internet entstehen als Ergebnis sozialer Prozesse und können auch als formaler Graph im Sinne der Mathematik interpretiert werden. Die Thematik Hyperlinks ist im Information Retrieval höchst aktuell, da Suchmaschinen die Link-Struktur bei der Berechnung ihrer Ergebnisse berücksichtigen. Algorithmen zur Bestimmung des "guten Rufs" einer Seite wie etwa PageRank von Google gewichten eine Seite höher, wenn viele links auf sie verweisen. Zu den neuesten Erkenntnissen über die Netzwerkstruktur des Internets liegen zwei sehr gut lesbare Bücher vor. Der Autor des ersten Buchs, der Wirtschaftswissenschaftler Huberman, ist Leiter einer Forschungsabteilung bei Hewlett Packard. Huberman beschreibt in seinem Buch zunächst die Geschichte des Internet als technologische Revolution und gelangt dann schnell zu dessen Evolution und den darin vorherrschenden Wahrscheinlichkeitsverteilungen. Oberraschenderweise treten im Internet häufig power-law Wahrscheinlichkeitsverteilungen auf, die der Zipf'schen Verteilung ähneln. Auf diese sehr ungleichen Aufteilungen etwa von eingehenden HypertextLinks oder Surfern pro Seite im Internet bezieht sich der Titel des Buchs. Diese immer wieder auftretenden Wahrscheinlichkeitsverteilungen scheinen geradezu ein Gesetz des Internet zu bilden. So gibt es z.B. viele Sites mit sehr wenigen Seiten und einige wenige mit Millionen von Seiten, manche Seiten werden selten besucht und andere ziehen einen Großteil des Internet-Verkehrs auf sich, auf die meisten Seiten verweisen sehr wenige Links während auf einige wenige populäre Seiten Millionen von Links zielen. Das vorletzte Kapitel widmen übrigens beide Autoren den Märkten im Internet. Spätestens hier werden die wirtschaftlichen Aspekte von Netzwerken deutlich. Beide Titel führen den Leser in die neue Forschung zur Struktur des Internet als Netzwerk und sind leicht lesbar. Beides sind wissenschaftliche Bücher, wenden sich aber auch an den interessierten Laien. Das Buch von Barabási ist etwas aktueller, plauderhafter, länger, umfassender und etwas populärwissenschaftlicher."

- Abstract
- Internet information retrieval is largely the preserve of search engines and the even more popular subject trees. Subject trees have adapted principles of conventional bibliographic classification for structuring hierarchic browsing interfaces, thus providing easily used pathways to their selected resources. This combination of browsing and selectivity is especially valuable to untrained users. For the forseeable future, it appears that subject trees will remain the Internet's only practicable use of classificatory methods for information retrieval

- Abstract
- Die Entstehung von Social Software ermöglicht es Nutzern, in großem Umfang im Netz zu publizieren. Bisher liegen aber nur wenige empirische Befunde zu funktionalen Eigenschaften sowie Qualitätsaspekten von Nutzerbeiträgen im Kontext von Informationsmanagement und Information Retrieval vor. Diese Arbeit diskutiert grundlegende Partizipationsformen, präsentiert empirische Studien über Social Tagging, Blogbeiträge sowie Relevanzbeurteilungen und entwickelt Design und Implementierung einer "sozialen" Informationsarchitektur für ein partizipatives Onlinehilfesystem.

- Abstract
- This paper describes the background underlying and the methods to be used in an investigation of use of the gopher protocol for browsing and searching for information via the Internet. Networked information resources are notoriously difficult to find; gopher is one attempt to facilitate the processes of organization and retrieval in that environment. Our project will design classification schemes based on traditional library models (i.e. Dewey and Library of Congress) and compare use of these to use of an existing gopher. We describe the project, the research questions, literature on related issues, the construction of the classification schemes, and the experimental methodology used

- Abstract
- Im Artikel geht es um Entwicklungstrends und Probleme, die mit dem schnellen Informationszuwachs im Internet verbunden sind. Es wird gezeigt, dass die Hauptschwierigkeiten nicht mit der Leistung von Software und der Hardware, sondern mit Besonderheiten des Sachgebietes zusammen hängen. Im Rahmen des Konzeptes der Informationsflüsse werden aktuelle Probleme des Information Retrieval, der Strukturierung des Informationsraums und dessen Verhältnis zum semantischen Raum behandelt. Der Artikel zeigt einige Lösungen dieser Probleme, die auf dem Textmining und fraktalen Modellen basieren.

- Abstract
- Basic skills of classification and subject indexing have been little taught in British library schools since automation was introduced into libraries. However, development of the Internet as a major medium of publication has stretched the capability of search engines to cope with retrieval. Consequently, there has been interest in applying existing systems of knowledge organization to electronic resources. Unfortunately, the classification systems have been adopted without a full understanding of modern classification principles. Analytico-synthetic schemes have been used crudely, as in the case of the Universal Decimal Classification (UDC). The fully faceted Bliss Bibliographical Classification, 2nd edition (BC2) with its potential as a tool for electronic resource retrieval is virtually unknown outside academic libraries
- Content
- A short discussion of using classification systems to organize the web, one of many such. The authors are both involved with BC2 and naturally think it is the best system for organizing information online. They list reasons why faceted classifications are best (e.g. no theoretical limits to specificity or exhaustivity; easier to handle complex subjects; flexible enough to accommodate different user needs) and take a brief look at how BC2 works. They conclude with a discussion of how and why it should be applied to online resources, and a plea for recognition of the importance of classification and subject analysis skills, even when full-text searching is available and databases respond instantly.
