In this paper, we argue that some tasks (e.g., meeting support) require more flexible hypermedia systems and we describe a prototype hypermedia system, DOLPHIN, that implements more flexibility. As part of the argument, we present a theoretical design ...

The emergent nature of structure is a crucial, but often ignored, constraint on authoring hypertexts. VIKI is a spatial hypertext system that supports the emergent qualities of structure and the abstractions that guide its creation. We have found that a ...

One of the crucial properties of documents through the ages has been their fixity. The ability to mark surfaces in relatively stable ways has made it possible for people distributed across space and time to see the same images and thereby to have access ...

In recent years, there has been significant growth in the use of computer networks to support electronic delivery of information. As the volume of available information has grown, a need for powerful tools that can manage access has arisen. It has been ...

Recently there has been a tendency for the research community to move away from closed hypermedia syustems, towards open hypermedia link services which allow third parties to produce applications so that they are hypertext-enabled. This paper explores ...

Networks are becoming increasingly available and hypertext systems with networking capabilities are currently enjoying exponential growth. The vast majority of hypertext systems were not, however, designed to cater for networking. This paper examines ...

This paper discusses the design and use of a generic composite mechanism in the object oriented DEVISE Hypermedia (DHM) development framework. The DHM development framework is based on the Dexter Hypertext Reference Model, which introduces a notion of ...

The Dexter Model defines the notion of atomic components and composite components, but it does not prescribe, nor it suggests, any particular structure for composite components. This paper proposes a specific type of composite component, called “...

At GMD-IPSI we are developing CoVer, a contextual version server for hypertext applications. Another characterization of CoVer is that CoVer integrates state-oriented versioning concepts with task-oriented versioning concepts. While other version models ...

Emerging software development environments are characterized by heterogeneity: they are composed of diverse object stores, user interfaces, and tools. This paper presents an approach for providing hypertext services in this heterogeneous setting. ...

Power plant operation and control in modern screen-based control rooms takes place using computer displays which are directly coupled to the plant state. However, operators are provided with operational instructions and background information by means ...

Creation and maintenance of links in large hypermedia documents is difficult. Motivated by an application to a federal clinical practice guideline for cancer pain management, we have developed and evaluated a repertory grid-based linking scheme we call ...

We propose a new navigation paradigm based on a spatial metaphor to help users access and navigate within large sets of documents. This metaphor is implemented by a computer artifact called an Interactive Dynamic Map (IDM). An IDM plays a role similar ...

This paper talks about clustering related nodes of an overview diagram to reduce its complexity and size. This is because although overview diagrams are useful for helping the user to navigate in a hypermedia system, for any real-world system these ...

In taxonomic reasoning tasks, such as scientific research or decision making, people gain insight and find new ideas through analysis of large numbers of factual data or material documents, which are generally disorganized and unstructured. Hypermedia ...

Multi-window interfaces allow users to work on logically independent taks simultaneously in different sets of windows and to move among these logical tasks at will (e.g., through selecting a window in a different task). Hypertext backtracking should be ...

In semantically rich hypertexts it is attractive to enable presentation of a network of nodes and link at different levels of abstraction. It is also important that the user can interact with the hypertext using a command repertoire that reflects the ...

A major obstacle hindering the advancement and commercial acceptance of hypermedia is the cost of converting paper based information into hypermedia form. The Hypermedia Authoring Research Toolkit (HART) was developed to support the human editor during ...

Hierarchical logical structure and hypertext links are complementary and can be combined to build more powerful document management systems. Previous work exploits this complementarity for building better document processors, browsers and editing tools, ...

Due to the growing complexity of modern hypertext applications, current hypertext systems require new mechanisms to support authoring and user navigation through large sets of documents connected by links. A general solution is to extent hypertext ...

Hypermedia designers have tried to move beyond the directed graph concept, which defines hypermedia structures as aggregations of nodes and links. A substantial body of work attempts to describe hypertexts in terms of extended or global spaces. ...

The architecture and some of the realized functionality of a prototype Editor's Workbench that supports the creation and maintenance of an object-oriented publisher's knowledge base is presented. The knowledge base is the repository not only for the ...

This paper discusses a semantic database approach to museum hypermedia systems based upon binary relations, with a restricted set of abstraction relationships. We describe examples of schema, queries and naviagaion aids for a prototype system designed ...
