Hyper-Document structure: maintaining discourse coherence in non-linear documents

The passage from linear text to hypertext poses the challenge of expressing discourse coherence in non-linear text, where linguistic discourse markers no longer work. While hypertext introduces new possibilities for discourse organisation, it also requires the use of new devices which can support the expression of coherence by exploiting the technical characteristics and expressive capabilities of the medium. In this paper we show how in hypertext the notion of abstract document structure encompasses animated graphics as a form of meta-language for discourse construction

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.

Structuring Hypertext Databases Using Hyper-Plate

Hypertext is the non-sequential access of information. The hypertext structure is powerful enough to represent informal, semiformal, and formal data. The construction of a hypertext document is a complex and laborious task. In general, hypertext documents are constructed manually. The manualmethod of construction may produce unstructured documents. It has been shown that a poor domerzt structure contributes to the lost in hyperspace syndrome. Hypertext Authoping System WypAS) was developed at the Depmtnaent of Systems Analysis, Miami University, Oxford, Ohio. In this study, Hyper-plate system was developed to structure documents created in HypAS. Hyperplate system is used to create hyper-plates, i.e., templates for hypertext documents. A hyper-plate defines the atbributes of a collection of nodes and the relationship among those nodes. The hyper-plate concept was conceived to aa'dress the issues of structuring and automating the construction of hypertext documents. The concepts of this study can be extended to any hypertext authoring system. The paper presents the design and implementation of Hyper-plate. The system components, data strctures, operations and its integralion with HpAS are described in detail

Usability of hypertext : factors affecting the construction of meaning

One type of hypertext application, information retrieval, has become increasingly popular and accessible due to the explosion of activity occurring on the World Wide Web. These hypertext documents are referred to as web sites. Readers can now access a multitude of web sites and retrieve a wide variety of information. The uniqueness of a hypertext document centers around the concept that text is broken into an array of non-sequential text chunks, or nodes, which are connected through links. The hypertext reading can be considered an interactive experience requiring the reader to effectively navigate the document. The potentially complex link and node structure awaiting hypertext readers can lead them into becoming lost in hyperspace Usable hypertext design will maximize document coherence and minimize readers\u27 cognitive overhead, allowing readers to create an accurate mental model of the hypertext structure. Usability testing is designed to determine how easily the functionality of a particular system can be used, In this case, the system under investigation is New Jersey Institute of Technology\u27s web site. The usability of a hypertext document is affected by design elements which contribute to the content and structure of the hypertext. These design elements include good navigation aids, clear link labels, and consistent page layout

Hypermedia 1990 structured Hypertext tutorial

Hypermedia 1990 structured Hypertext tutorial is presented in the form of view-graphs. The following subject areas are covered: structured hypertext; analyzing hypertext documents for structure; designing structured hypertext documents; creating structured hypertext applications; structuring service and repair documents; maintaining structured hypertext documents; and structured hypertext conclusion

Visualising Discourse Structure in Interactive Documents

In this paper we introduce a method for generating interactive documents which exploits the visual features of hypertext to represent discourse structure. We explore the consistent and principled use of graphics and animation to support navigation and comprehension of non-linear text, where textual discourse markers do not always work effectively

Are we talking about the same structure?: A unified approach to hypertext links, xml, rdf and zigzag

There are many different hypertext systems and paradigms, each with their apparent advantages. However the distinctions are perhaps not as significant as they seem. If we can reduce the core linking functionality to some common structure, which allows us to consider hypertext systems within a common model, we could identify what, if anything, distinguishes hypertext systems from each other. This paper offers such a common structure, showing the conceptual similarities between each of these systems and paradigms

The present article is devoted to one of the crucial problem in compiling electronic specialized dictionary, namely to structure modeling of power plant machine building term system by using the hypertext. The stages of creating electronic lexicographic hypertext are described in detail, general principles of revealing the structure of term subsystems, considering their internal and external relations, are determined, the forms of hypertext representation in the dictionary are specifie

Exploring (the poetics of) strange (and fractal) hypertexts

The ACM Hypertext conference has a rich history of challenging the node-link hegemony of the web. At Hypertext 2011 Pisarski [12] suggested that to refocus on nodes in hypertext might unlock a new poetics, and at Hypertext 2001 Bernstein [3] lamented the lack of strange hypertexts: playful tools that experiment with hypertext structure and form. As part of the emerging Strange Hypertexts community project we have been exploring a number of exotic hypertext tools, and in this paper we set out an early experiment with media and creative writing undergraduates to see what effect one particular form – Fractal Narratives, a hypertext where readers drill down into text in a reoccurring pattern – would have on their writing. In this particular trial, we found that most students did not engage in the structure from a storytelling point of view, although they did find value from a planning point of view. Participants conceptually saw the value in non-linear storytelling but few exploited the fractal structure to actually do this. Participant feedback leads us to conclude that while new poetics do emerge from strange hypertexts, this should be viewed as an ongoing process that can be reinforced and encouraged by designing tools that highlight and support those emerging poetics in a series of feedback loops, and by providing writing contexts where they can be highlighted and collaboratively explore

Using string-matching to analyze hypertext navigation

A method of using string-matching to analyze hypertext navigation was developed, and evaluated using two weeks of website logfile data. The method is divided into phases that use: (i) exact string-matching to calculate subsequences of links that were repeated in different navigation sessions (common trails through the website), and then (ii) inexact matching to find other similar sessions (a community of users with a similar interest). The evaluation showed how subsequences could be used to understand the information pathways users chose to follow within a website, and that exact and inexact matching provided complementary ways of identifying information that may have been of interest to a whole community of users, but which was only found by a minority. This illustrates how string-matching could be used to improve the structure of hypertext collections
