Dynamic hypertext: querying and linking (original) (raw)

Modeling Links in HypertextfHypermedia Abstract

The links between the nodes constitute one of the most significant aspects of the hypertext, and very much contribute to the support of their dynamic interaction paradigm, so relevant to the implementation of effective applications. In this paper we firstly recall the characteristics of the hypertext, pointing out some of the main problems the hypertext applications' designer must face. Afterwards, we outline a hypertext design methodology that leads to a consistent design of the nodes' structure, and allows modelling the different kind of links that can exist among the nodes. In particular, introducing the "concept space" allows an effective modelling of the intensional links. Finally, we discuss some general implementation aspects, and point out the need of offering to the user multiple and interchangeable interaction paradigms. During the last years, the interest in hypertext has accelerated sharply ([Conklin87]). Several factors explain it: more powefil worksta...

A I ] 1 6 O ct 2 01 8 Conceptual Analysis of Hypertext

2018

In this chapter tools and techniques from the mathematical theory of formal concept analysis are applied to hypertext systems in general, and the World Wide Web in particular. Various processes for the conceptual structuring of hypertext are discussed: summarization, conceptual scaling, and the creation of conceptual links. Well-known interchange formats for summarizing networked information resources as resource meta-information are reviewed, and two new interchange formats originating from formal concept analysis are advocated. Also reviewed is conceptual scaling, which provides a principled approach to the faceted analysis techniques in library science classification. The important notion of conceptual linkage is introduced as a generalization of a hyperlink. The automatic hyperization of the content of legacy data is described, and the composite conceptual structuring with hypertext linkage is defined. For the conceptual empowerment of the Web user, a new technique called concep...

Hypertext Structure as the Event of Connection

Miles, Adrian. "Hypertext Structure as the Event of Connection." 12th ACM Hypertext Conference. Aarhus: ACM, 2001. This paper received the "Ted Nelson Award" at the 2001 Association of Computing Machinery Hypertext Conference. It conforms to the ACM styleguide, and has been written as a reasonably straightforward conference paper. Extensive use of subheadings has been made to 'atomise' the writing. This paper argues that links have performative force which allows for their 'meaning' to be understood respectively. This is in contradistinction to most theories of hypertext linking which regard linking as a foward projected understanding that needs to describe what it is, ahead of itself. Schematically, links create connection, which links and how cannot be predetermined, and so structure is determined retrospectively.

Referencing within evolving hypertext

The classic hypertext model omits the process of text growth, evolution and synthesis. With hypertext creation becoming increasingly collaborative and change timescales becoming shorter, explicitly addressing text evolution is the key to the next stage of hypertext development. Uniform Resource Identifier (URI) is a proven general concept that enabled the Web. In application to versioned deep hypertext, expressive power of a classical hyperlink becomes insufficient. Based on the Causal Trees model, we introduce a minimalistic but powerful query language of specifiers that provides us great flexibility of referencing within a changing hypertext. Specifiers capture the state of the text, point at changes, expose authorship or blend branches. Being a part of an URI, a specifier puts advanced distributed revision control techniques within reach of a regular web user.

Second international Workshop on Dynamic and Adaptive Hypertext

2011

Dynamically generated hypertext adapted and personalized to the users/needs and abilities has proven to be a very successful technique over the last decade and a half. It is particularly helpful for reducing the information overload that frequently occurs in the modern information: driven world. Adaptive hypertext is equally effective for accessing many types of items, be it news, products, artifacts or descriptions thereof in electronic shops, libraries or museums, or even learning materials.

Structural analysis of hypertexts: identifying hierarchies and useful metrics

1992

Abstract Hypertext users often suffer from the ��lost in hyperspace�� problem: disorientation from too many jumps while traversing a complex network. One solution to this problem is improved authoring to create more comprehensible structures. This paper proposes several authoring tools, based on hypertext structure analysis. In many hypertext systems authors are encouraged to create hierarchical structures, but when writing, the hierarchy is lost because of the inclusion of cross-reference links.

Retrieval of Hypertext Structures

1994

Abstract Hypertext, often considered the successor of the book, is a new medium that adds non-linearity as a key feature. However, hypertext is also a generalization of text databases, adding structural-and cross-reference links. This paper reflects research on the retrieval of structural information in distributed hypertexts, like the World-Wide Web (WWW).

Soft-link hypertext for information retrieval

2002

This paper provides a formal specification in Z of a new intelligent hypertext model called the soft-link hypertext model (SLHM). This model has been implemented and extensively tested, and provides a new methodology for constructing the future generation of information retrieval systems. SLHM has the following three major advantages. First, it is automatically formulated. Second, powerful neural learning mechanisms are applied, thereby improving its efficiency and applicability.

Making connections: the logical structuring of hypertext documents

Instructional Science, 1992

The results from an experiment analysing hypertextual semantic linking is reported. In the study participants are asked to describe logical relationships between related, semi-related and unrelated paragraphs of text. It is concluded that existence and ‘themes’ of relationships are (as expected) fairly consistently recognised, however, specific relationships do not readily fall into ‘natural’ predicate like statements. Purely ‘thematic’ relationships, or a ‘palette’ of available relationships might be the more practical approach. Further work on dynamic linking in hypertext documents is also reported. Dynamic linking eliminates some of the problems associated with a mismatch between the mental models of authors and readers and allows the readers to construct their own hypertexts from linear documents. This approach offers useful data on logical connectivity in hypertext documents but also represents an alternative to conventional hypertext authoring and reading.

Semantic Indexing and Typed Hyperlinking

1997

In this paper, we describe linguistically sophisticated tools for the automatic annotation and navigation of on-line documents. Creation of these tools relies on research into nite-state technologies for the design and development of lexicallyintensive semantic indexing, shallow semantic understanding, and content abstraction techniques for texts. These tools utilize robust language processing techniques to generate multi-purpose data structures called lexical webs, used in the system TexTract, an automated semantic indexing program designed to parse, index, and hyperlink electronic documents.

Exploiting navigation capabilities in hypertext/hypermedia

The Dynamic Hypertext

Electronic hypertext catalogues provide an important channel for information provision. One relatively traditional set of tools for creating hypertext in Homeric oral song is names. For example, names whithin the web of oral epic song provide users with visual maps linked together by meter. Hypertextual lists and catalogues challenge the very foundations of producing unified, coherent texts, narrative and poetry. Consider the following formulation by Pucci: 1

Content oriented relations between text units---a structural model for hypertexts

Proceeding of the ACM conference on Hypertext - HYPERTEXT '87, 1987

A common feature of various recently developed information systems is the decomposition of linear document structures which are enforced by conventional print media. Instead, a network organisation of information units of different forms (textual, graphical, pictorial and even auditory presentation modes may be combined) is provided. Documents organized this way are called 'hypertexts'. However, two questions arise immediately when an effort is made to build information systems on the basis of this conception:

Cluster analysis for hypertext systems

1993

Identifying nodes of information that are highly related has many applications in any information systems, and in particular in hypertext systems. In this paper we present a technique to identify \natural" clusters in a hypertext. A natural cluster is a cluster that is not arbitrary, but depends only on intrinsic properties of the hypertext. In our case, the property we will use to identify the clusters is the number of independent paths between nodes. Using the graph theoretic de nition of k-edge-components we present two clustering techniques: aggregation and a level clustering. We then use those techniques to cluster three medium sized hypertexts that were developed by di erent authors for di erent users, using di erent methodologies. We also show how to use clustering to improve data display, browsing and retrieval.

Automatic hypertext link typing

1996

ABSTRACT We present entirely automatic methods for gathering documents for a hypertext, linking the set, and annotating those connections with a description of the type (ie, nature) of the link. Document linking is based upon high-quality information retrieval techniques developed using the Smart system.
