- Abstract
- Im Projekt Virtuelle Informationsräume soll das Suchen in elektronischen Marktplätzen verbessert werden. Dabei soll die Informationsquellenauswahl optimiert, die eigentliche Suche unterstützt und die Präsentation der Ergebnisse verbessert werden. Im vorliegenden Beitrag wird eine Verfahren zur Visualisierung von Suchergebnissen vorgestellt, welches die Suchergebnisse eingebettet in die Struktur des elektronischen Marktplatzes zeigt

- Abstract
- The Konstanz-Hypertext-System (KHS) is an open hypertext system which employs internal and external information sources to satisfy the user's need for information when navigating through a hypertext. E-mail, Gopher and online databases are available in KHS as external information sources. The main tasks which must be carried out during an online search are analysis of the question, selection of the databases, formulation of a search strategy, online search, feedback and the presentation of the results. All of these tasks are supported within KHS, but special emphasis is given to database selection. Introduces a new method for selecting relevant online databases with KHS using the database descriptions from several hosts

- Abstract
- Quality, quality control, quality assurance and quality management are becoming increasingly important in using online services and online databases. Focuses on the production of online bibliographic databases and discusses possible attributes responsible for the quality of this type of online database. Considers different stages in the production of the databases: acquisition of the original documents; quality of document analysis in the selection of the documents; and subject and bibliographic analysis. Shows how the quality attributes of the different production steps may be measured. Describes, as an example, a database production system with its testing routines and reference data
