Abstract

We present a declarative language for the construction of hypertext views on databases. The language is based on an object-oriented data model and a simple hypertext model with reference and inclusion links. A hypertext view specification consists in a collection of parameterized node schemes which specify how to construct node and links instances from the database contents. We show how this language can express different issues in hypertext view design. These include: the direct mapping of objects to nodes; the construction of complex nodes based on sets of objects; the representation of polymorphic sets of objects; and the representation of tree and graph structures. We have defined sublanguages corresponding to particular database models (relational, semantic, object-oriented) and implemented tools to generate Web views for these database models

Abstract

HIFI (ESPRIT project 6532) creates a set of tools to allow a reader to access a large body of heterogeneous information, managed by external databases created beforehand, through a hypertext interface. The HIFI approach is a model-based description of the hypertext application as it appears to the reader. A declarative and/or operational mapping translates hypertext operations (search, queries and navigation) into operations on the underlying information base and also 'materialises' hypertext objects, using objects of the underlying databases. The system supports hypertext development. Illustrates this with the cooperation of end users as partners or project sponsors

Abstract

The reader of a hypertext document in a web environment, if maximum use of the document is to be obtained, must visualize the overall structure of the paths through the document as well as the document space. Graphic visualization displays of this space, produced to assist in navigation, are classified into four groups, and Heo and Hirtle compare three of these classes as to their effectiveness. Distortion displays expand regions of interest while relatively diminishing the detail of the remaining regions. This technique will show both local detail and global structure. Zoom techniques use a series of increasingly focused displays of smaller and smaller areas, and can reduce cogitative overload, but do not provide an easy movement to other parts of the total space. Expanding outline displays use a tree structure to allow movement through a hierarchy of documents, but if the organization has a wide horizontal structure, or is not particularly hierarchical in nature such display can break down. Three dimensional layouts, which are not evaluated here, place objects by location in three space, providing more information and freedom. However, the space must be represented in two dimensions resulting in difficulty in visually judging depth, size and positioning. Ten students were assigned to each of eight groups composed of viewers of the three techniques and an unassisted control group using either a large (583 selected pages) or a small (50 selected pages) web space. Sets of 10 questions, which were designed to elicit the use of a visualization tool, were provided for each space. Accuracy and time spent were extracted from a log file. Users views were also surveyed after completion. ANOVA shows significant differences in accuracy and time based upon the visualization tool in use. A Tukey test shows zoom accuracy to be significantly less than expanding outline and zoom time to be significantly greater than both the outline and control groups. Size significantly affected accuracy and time, but had no interaction with tool type. While the expanding tool class out performed zoom and distortion, its performance was not significantly different from the control group.

Abstract

Although the object-oriente paradigm is well suited for modelling self-contained independent objects, it is not suited for modelling persistent relations (static links) between abstract data objects. At the same time, the concept of computer-navigable links is an integral part of hypermedia paradigm. In contrast to multimedia, where the object-oriented paradigm plays a leading role, the 'static link' deficiency considerably reduces the application of object-oriented methods in hypermedia. Presents a new logical data model (the HM Data Model) which incorporates the well-known principles of object-oriented data modelling into the management of large-scale, multi-user hypermedia databases. The model is based on the notion of abstract hypermedia data objects called S-collections. Computer-navigable links approach not only overcomes the static link deficiency of the object-oriented paradigm, but also supports modularity, incremental development, and flexible versioning, and provides a solid logical basis for sematic modelling

Abstract

The C(K)onstance Hypertext System (KHS) is an elaborated example of an open hypertext system. Open hypertext systems combine heterogeneous resources and different hypertext applications such as e-mail, text and image hypertexts with access to online databases or other information resources. These hypertexts, to which heterogeneous users have access, grow steadily in size. This paper takes an object-oriented approach and proposes a rigorous typing of hypertext objects to overcome the problems of open hypertext. The advantage of this typing is shown on an e-mail hypertext as a special application of the KHS system. KHS is written in Smalltalk and is being developed on UNIX-machines

Abstract

In important stage in the process of retrieval of objects from a hypertext database is the creation of a set of inter-nodal links that are intended to represent the relationships existing between objects; this operation is often undertaken manually, just as index terms are often manually assigned to documents in a conventional retrieval system. Studies of conventional systems have suggested that a degree of consistency in the terms assigned to documents by indexers is positively associated with retrieval effectiveness. It is thus of interest to investigate the consistency of assignment of links in separate hypertext versions of the same full-text document, since a measure of agreement may be related to the subsequent utility of the resulting hypertext databases. The calculation of values indicating the degree of similarity between objects is a technique that has been widely used in the fields of textual and chemical information retrieval; in this paper we describe the application of arithmetic coefficients and topological indices to the measurement of the degree of similarity between the sets of inter-nodal links in hypertext databases. We publish the results of a study in which several different of links are inserted, by different people, between the paragraphs of each of a number of full-text documents. Our results show little similary between the sets of links identified by different people; this finding is comparable with those of studies of inter-indexer consistency, where it has been found that there is generally only a low level of agreement between the sets of idenx terms assigned to a document by different indexers

Abstract

Most existing hypermedia authoring systems are intended for use on desktop computers. These systems are typically designed for the creation of 2D documents and therefore employ 2D authoring mechanisms. In contrast, authoring systems for nontraditional multimedia/hypermedia experiences for 3D virtual or augmented worlds focus mainly on creating separate media objects and embedding them within the user's surroundings. As a result, linking these media objects to create 3D hypermedia is a tedious manual task. To address this issue, we present an authoring tool for creating and editing linked 3D hypermedia narratives that are interwoven with a wearable computer user's surrounding environment. Our system is designed for use by authors who are not programmers, and allows them to preview their results on a desktop workstation, as well as with an augmented or virtual reality system.

Abstract

Describes an SGL relational database schema for representing the objects in HyperCard, along with a technique for automatically populating this schema from a HyperCard stack using the facilities in HyperTalk with calls to the database manager. The stabndard relational database query language SQL can then be used to perform more general hypertext searches than are possible with the string search feature found in most hypertext browsing environments. These techniques, although demonstrated specially usinf HyperCard and Oracle for Macintosh, are generally applicable to a wide range of hypertext systems and relational databases

Abstract

Examines the use of hypertexts as a tool to present educational material by projecting its nodes. The reader becomes a spectator who is passively subject to the navigation effected by the speaker. The author extends his influence to the reading process by navigating according to his own requirements. Presents a prototype developed specifically to increase the efficiency of a hypertext used for this form of communication, allowing the teacher to choose which objects will be projected and when they will appear

Abstract

Large hypertext systems have been many benefits but can be difficult to build and use. To help overcome these obstacles, a method under development at Hewlett-Packard assists authors in creating usable hypertext. A Wizard of Oz experiment, to see what users liked and disliked, showed the need for a set of hypertext construction rules to ensure usability. Following these rules, and with computer assistance, authors are expected to do a tasks analysis of users' activities, to identify critical objects and create content nodes for them, to create links between nodes within clearly defined and cognitively justified limits, and to conduct usability tests on the resulting hypertext volume. The authoring system described has been developed for the HP help system, which has been adopted as the common help delivery system for developers of Common Open Systems Environment on Unix-like platforms

Abstract

The concept of a system combining information in both textual and pictorial format was first suggested by Vannevar Bush in 1945. The present hypermedia system was originally developed by Tim Berners Lee at CERN in 1989 and provides access to brief documents, which are interlinked and contain text, images, sound and video. The system has become widely available through the WWW, which enables users to 'navigate' through related information. Recent developments include the ability to view objects in virtual reality and the automatic generation of document links

Abstract

Current hypertext systems have been widely and effectively used on relatively small data volumes. Explores the potential of database technology for aiding the implementation of hypertext systems holding very large amounts of complex data. Databases meet many requirements of the hypermedium: persistent data management, large volumes, data modelling, multi-level architecture with abstractions and views, metadata integrated with operational data, short-term transaction processing and high-level end-user languages for searching and updating data. Describes a system implementing the storage, retrieval and recall of trails through hypertext comprising textual complex objects (to illustrate the potential for the use of data bases). Discusses weaknesses in current database systems for handling the complex modelling required

Abstract

Introduces what automatic authoring of a hypertext for information retrieval means. The most difficult part of the automatic construction of a hypertext is the creation of links connecting documents or document fragments that are related. Becaus of this, to many researchers it seemed natural to use information retrieval techniques for this purpose, since information retrieval has always dealt with the construction of relationships between objects mutually relevant. Presents a survey of some of the attempts toward the automatic construction of hypertexts for information retrieval. Identifies and compares scope, advantages and limitations of different approaches. Points out the main and most successful current lines of research
