Abstract

Im Internet steht inzwischen eine enorme und ständig wachsende Menge von Dokumenten zur Verfügung. Es wird daher auch für wissenschaftliche Informationssuchende neben traditionellen Printveröffentlichungen zu einer wichtigen Informationsquelle. Im Gegensatz zur relativ geordneten Welt der gedruckten Publikationen ist es jedoch schwierig, gezielt Informationen im Internet zu finden. Ursachen dafür sind neben sehr unterschiedlicher Qualität und Zielsetzung auch Charakteristika von Internetdokumenten, wie z.B. die Darstellung als offener, verteilter Hypertext oder ihre leichte Veränderbarkeit. In der vorliegenden Arbeit wird untersucht, inwieweit die gegenwärtigen Suchdienste für das WWW Anforderungen an die wissenschaftliche Informationssuche entsprechen. Dazu wird ein Überblick über die Arbeitsweisen sowie generelle Stärken und Schwächen verschiedener Typen von Suchdiensten (roboterbasierte, manuell erstellt sowie simultane) gegeben

Abstract

Wie bei einem Baukasten können die Kinder Figuren auswählen, sie in bunten Szenarien plazieren und mit Hilfe leicht verständlicher Symbole die Handlung und das Zusammenspiel der Figuren steuern. Labyrinthe und Hindernisläufe helfen ihrem Kind spielerisch, Probleme zu lösen und die Merkfähigkeit zu entwickeln

Abstract

Florian Rötzer hat in einem langen Gespräch mit Sahra Wagenknecht, aus dem das Buch "Couragiert gegen den Strom. Über Goethe, die Macht und die Zukunft!" hervorgegangen ist, u.a. darüber gesprochen, wie Kultur und philosophisches Denken die politischen Vorstellungen und den politischen Stil der linken Politikerin geprägt haben. Dabei ging es auch um den Kapitalismus und dessen Abschaffung, um den Kern linker Politik, die Konkurrenz in der Wirtschaft und auch über die Digitalisierung sowie die Ideen, mit einer Maschinensteuer oder einem bedingungslosen Grundeinkommen das Schlimmste zu verhindern. Telepolis veröffentlicht einen Auszug aus dem Buch, das im Westendverlag erschienen ist.

Abstract

Am Beispiel der Knochenmarktransplantation, eines medizinischen Spezialgebietes, wird im folgenden dargelegt, wie man BenutzerInnen eine großen Teil des Aufwandes bei der Wissensbeschaffung abnehmen kann, indem man Suchergebnisse aus dem Netz fragebezogen zusammenfaßt. Dadurch wird in zeitkritischen Situationen, wie sie in Diagnose und Therapie alltäglich sind, die Aufnahme neuen Wissens ermöglicht. Auf einen Überblick über den Stand des Textzusammenfassens und der Ontologieentwicklung folgt eine Systemskizze, in der die Informationssuche im WWW durch ein kognitiv fundiertes Zusammenfassungssystem ergänzt wird. Dazu wird eine Fach-Ontologie vorgeschlagen, die das benötigte Wissen organisiert und repräsentiert.

Abstract

Zu den großen Herausforderungen einer sinnvollen Suche im WWW gehören die riesige Menge des Verfügbaren und die Sparchbarrieren. Verfahren, die die Web-Ressourcen im Hinblick auf ein effizienteres Retrieval inhaltlich strukturieren, werden daher ebenso dringend benötigt wie Programme, die mit der Sprachvielfalt umgehen können. Im folgenden Vortrag werden wir einige Ansätze diskutieren, die zur Bewältigung der beiden Probleme derzeit unternommen werden

Abstract

The automated categorisation (or classification) of texts into topical categories has a long history, dating back at least to 1960. Until the late '80s, the dominant approach to the problem involved knowledge-engineering automatic categorisers, i.e. manually building a set of rules encoding expert knowledge an how to classify documents. In the '90s, with the booming production and availability of on-line documents, automated text categorisation has witnessed an increased and renewed interest. A newer paradigm based an machine learning has superseded the previous approach. Within this paradigm, a general inductive process automatically builds a classifier by "learning", from a set of previously classified documents, the characteristics of one or more categories; the advantages are a very good effectiveness, a considerable savings in terms of expert manpower, and domain independence. In this tutorial we look at the main approaches that have been taken towards automatic text categorisation within the general machine learning paradigm. Issues of document indexing, classifier construction, and classifier evaluation, will be touched upon.

Abstract

After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.
