The Hypertext Internet Connection: E-mail, Online Search, Gopher

In this paper we show how to handle and organize the large amount of information accessible through the Internet or other public communication networks in a hypertext environment. The C(K)onstance-Hypertext-System (KHS) uses typed units to indicate the differences and the content and structure of information, comprising text, forms, images pointers to external information. We show how to imbed Internet services, which usual require rather different interaction styles, such as point-to-point communication (e-mail query formulation (online databases) or browsing (Gopher) into the uniform interaction model of the KHS. The integration of Internet services in an open hypertext environment produces value-adding effects which are also discussed. (DIPF/Orig.

A Homogenous Interaction Platform for Navigation and Search in and from Open Hypertext Systems

In response to the challenge of open hypertext systems allowing access to heterogenous information resources in the world-wide commercial and scientific information market, we propose a hypertext system model and architecture based on typed objects and links making possible semantically controlled access to information units within the hypertext, as well as to the outside information systems world. We concentrate particularly on a common interaction platform by describing the ditTerent browser types of the Constance hypertext system (KIIS), and describe in more detail various different navigation techniques and term-based retrieval methods- thus furthering a productive partnership between information retrieval and hypertext
