- 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 focus of this article is to develop a map display for information retrieval. Through an examination of relationships among visual displays, information retrieval, and browsing, advantages of visual displays for information retrieval are characterized as (1) the ability to convey a large amount of information in a limited space, (2) the potential to reveal semantic relationships of terms and documents; and (3) the facilitation of browsing and perceptual inferences on retrieval interfaces. These advantages are further demonstrated through a map display generated by a neural network's self-organizing algorithm. The map display detects complex relationships among given documents, and reveals the relationships through a spatial arrangement of terms abstracted from the documents. The map display also provides interactive tools to allow the user to interact with the underlying information. Examples of the map displays show that such map displays can be used both as an overview tool and an access or exploration tool, and the map displays will likely increase the amount of information that the user is willing to browse

- Abstract
- Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

- Abstract
- Compares 3 different map displays generated from the same set of documents by either a self-organizing algorithm or human subjects. Aims to: evaluate usefulness of map displays for information seeking and observe how people search and browse on them and to compare their structural and visual features. 68 subjects were randomly assigned to 3 selected map displays. They were asked to perform simple retrieval tasks, and their performances were analyzed. Both the organization and the visual appearance of displays had significant effects on subjects' searching and browsing on the map displays

- Abstract
- This paper shows that, given co-citation data, Kohonen feature mapping produces results quite similar to those of multidimensional scaling, the traditional mode for computer-assisted mapping of intellectual domains. It further presents a Kohonen feature map based on author co-citation data that links author names to information about them on the World Wide Web. The results bear on a goal for present-day information science: the integration of computerized bibliometrics with document retrieval
