    Abstract
    Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.

    Abstract
    Purpose - The purpose of this paper is to explore the application of post-structuralist theory to understanding hypertext and the World Wide Web, and the challenge posed by digital information technology to the practices of the information profession. Design/methodology/approach - The method adopted is that of a critical study. Findings - The paper argues for the importance of post-structuralism for an understanding of the implications of digital information for the information management profession. Originality/value - Focuses on an epistemological gap between the traditional practices of the information profession, and the structure of the World Wide Web.

    Abstract
    At a finer level, Amitay speculates about the use of language on the Web. The Web may be one large corpus of text, but she suggests that communities will express themselves by the conventions used for writing hypertext. It may be that new information technologies will spawn new communities.

    Abstract
    The Ambient Wood project, carried out as part of the Equator project, set out to provide an augmented learning experience for children in an outdoor environment. Using a variety of devices, the children gathered information about the woodland habitats performing basic scientific enquiry and hypothesis testing. In this paper, we describe the supporting information infrastructure used in the project, focusing on how hypermedia tools and techniques were used to structure and deliver the information to the children, helping to orchestrate the learning activities.

    Abstract
    The ease of linking and hopping from one text to another that we associate today with the World Wide Web was implemented in a different context prior to the Web. The creation of "hypertext" has a long and interesting history prior to the Web, as this article demonstrates. At the time it was issued, the HyperCard software application was expected to be the foundation of a widely-used new means of information organization. We can see now that the key ideas of hypertext were present in HyperCard, without the ease of use of subsequent World Wide Web features.

    Abstract
    Textbooks are more available in electronic format now than in the past. Because textbooks are typically large, the end user needs effective tools to rapidly access information encapsulated in textbooks stored in digital libraries. Statistical similarity-based links among hypertextbooks are a means to provide those tools. In this paper, the design and the implementation of a tool that generates networks of links within and across hypertextbooks through a completely automatic and unsupervised procedure is described. The design is based an statistical techniques. The overall methodology is presented together with the results of a case study reached through a working prototype that shows that connecting hyper-textbooks is an efficient way to provide an effective retrieval capability.

    Abstract
    The primary purpose of the study was to identify motivations for hyperlinking in scholarly electronic articles. Fifteen Indiana University faculty and graduate students who had published at least one scholarly electronic article containing at least one external hyperlink were surveyed. Through a series of qualitative interviews, 19 different hyperlinking motivations, classified into the three motivational groups -scholarly, social, and technological-along the dimensional ranges of their properties, were identified. The vast majority of the hyperlinks were attributed to more than one motivation by the authors. The empirical findings of the study demonstrated that scholars use hyperlinks for a variety of purposes, and that their hyperlinking behavior frequently results from a complex interplay of motivations

    Abstract
    Adaptive Hypermedia has sought to tackle the problems of dealing with complex, heavily structured information and the presentation of views of that structure to users. Increasingly, adaptive content is achieved through different forms of context. Using two case-study applications, we will reflect on how Augmented Reality may present solutions to a number of Adaptive Hypermedia presentation problems. Each case study describes a different physical interaction metaphor for exposing the complex adaptation of hypermedia content in an intuitive way. The preliminary findings of our early evaluations are discussed. Finally, conclusions are drawn as to how Augmented Reality applications could use the modelling techniques of the Adaptive Hypermedia community to deal more easily with complex information.

    Abstract
    We present a general framework for cross-media annotation that can be used to support the many different forms and uses of annotation. Specifically, we discuss the need for digital annotation of printed materials and describe how various technologies for digitally augmented paper can be used in support of work practices. The state of the art in terms of both commercial and research solutions is described in some detail, with an analysis of the extent to which they can support both the writing and reading activities associated with annotation. Our framework is based on an extension of the information server that was developed within the Paper++ project to support enhanced reading. It is capable of handling both formal and informal annotation across printed and digital media, exploiting a range of technologies for information capture and display. A prototype demonstrator application for mammography is presented to illustrate both the functionality of the framework and the status of existing technologies.

    Abstract
    Weblogs are gaining momentum as one of most versatile tools for online scholarly communication. Since academic weblogs tend to be used by scholars to position themselves in a disciplinary blogging community, links are essential to their construction. The aim of this article is to analyze the reasons for linking in academic weblogs and to determine how links are used for distribution of information, collaborative construction of knowledge, and construction of the blog's and the blogger's identity. For this purpose I analyzed types of links in 15 academic blogs, considering both sidebar links and in-post links. The results show that links are strategically used by academic bloggers for several purposes, among others to seek their place in a disciplinary community, to engage in hypertext conversations for collaborative construction of knowledge, to organize information in the blog, to publicize their research, to enhance the blog's visibility, and to optimize blog entries and the blog itself.

    Abstract
    Fast, effective, and adaptable techniques are needed to automatically organize and retrieve information an the ever-increasing World Wide Web. In that respect, different strategies have been suggested to take hypertext links into account. For example, hyperlinks have been used to (1) enhance document representation, (2) improve document ranking by propagating document score, (3) provide an indicator of popularity, and (4) find hubs and authorities for a given topic. Although the TREC experiments have not demonstrated the usefulness of hyperlinks for retrieval, the hypertext structure is nevertheless an essential aspect of the Web, and as such, should not be ignored. The development of abstract models of the IR task was a key factor to the improvement of search engines. However, at this time conceptual tools for modeling the hypertext retrieval task are lacking, making it difficult to compare, improve, and reason an the existing techniques. This article proposes a general model for using hyperlinks based an Probabilistic Argumentation Systems, in which each of the above-mentioned techniques can be stated. This model will allow to discover some inconsistencies in the mentioned techniques, and to take a higher level and systematic approach for using hyperlinks for retrieval.

    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
    When the Web was invented, it was touted as a novel nonlinear medium for the written word. No longer would we be constrained by linear presentations! Hyperlinks would allow us to jump haphazardly from page to page, chapter to chapter, idea to idea! Texts would no longer need to run from beginning to end! This is misleading. A printed book is also multidimensional and potentially nonlinear. We can open it to any page, from any other page, for any reason. We can open several books at once. In fact, what makes a book special is its combination of linear structure (the order of the words) and nonlinear physicality (the bound papers). This linear/nonlinear duality is enhanced further by the index, which maps linearly sequenced pages in a nonlinear, informationally ordered structure (architecture). In truth, the online environment is crippled by an absence of linear structure. Imagine selecting a hard cover book, tearing off the covers, ripping pages into small pieces, and throwing them in a box. That box is like a computer file system, and the paper scraps are Web documents. Only one scrap can be retrieved from the box at a time, and it must be replaced before another can be accessed. Page numbers are meaningless. Global context is destroyed. And without page numbers or context, what happens to the index?

    Abstract
    There has been an increased growth in the use of hypermedia to deliver learning and teaching material. However, much remains to be learned about how different learners perceive such systems. Therefore, it is essential to build robust learning models to illustrate how hypermedia features are experienced by different learners. Research into individual differences suggests cognitive styles have a significant effect on student learning in hypermedia systems. In particular, Witkin's Field Dependence has been extensively examined in previous studies. This article reviews the published findings from empirical studies of hypermedia learning. Specifically, the review classifies the research into five themes: nonlinear learning, learner control, navigation in hyperspace, matching and mismatching, and learning effectiveness. A learning model, developed from an analysis of findings of the previous studies, is presented. Finally, implications for the design of hypermedia learning systems are discussed

    Content
    This article reports an applied research on the construction and implementation of a semantically structured conceptual prototype to help in the organization and representation of human knowledge in hypertextual systems, based on four references: the Facet Analysis Theory (FAT), the Conceptual Map Theory, semantic structure of hypertext links and the technical guidelines of the Associacao Brasileira de Normas Técnicas (ABNT). This prototype, called Modelo Hipertextual para Organizacao de Documentos (MHTX) - Model For Hypertext Organization of Documents HTXM - is formed by a semantic structure called Conceptual Map (CM) and Expanded Summary (ES), the latter based on the summary of a selected doctoral thesis to which access points were designed. In the future, this prototype maybe used to implement a digital libraty called BTDECI - UFMG (Biblioteca de Teses e Dissertacöes do Programa de Pós-Graduacao da Escola de Ciência da Informacao da UFMG - Library of Theses and Dissertations of the Graduate Program of School of Information Science of Universidade Federal de Minas Gerais).

    Abstract
    The effects of link annotations on user search performance in hypertext environments having deep (layered) and shallow link structures were investigated in this study. Four environments were tested-layered-annotated, layered-unannotated, shallow-annotated, and shallow-unannotated. A single document was divided into 48 sections, and layered and unlayered versions were created. Additional versions were created by adding annotations to the links in the layered and unlayered versions. Subjects were given three queries of varying difficulty and then asked to find the answers to the queries that were contained within the hypertext environment to which they were randomly assigned. Correspondence between the wording links and queries was used to define difficulty level. The results of the study confirmed previous research that shallow link structures are better than deep (layered) link structures. Annotations had virtually no effect on the search performance of the subjects. The subjects performed similarly in the annotated and unannotated environments, regardless of whether the link structures were shallow or deep. An analysis of question difficulty suggests that the wording in links has primacy over the wording in annotations in influencing user search behavior.
