Improving Web Prefetching by Making Predictions at Prefetch
2007
Most of the research attempts to improve Web prefetching techniques have focused on the prediction algorithm with the objective of increasing its precision or, in the best case, to reduce the user's perceived latency. In contrast, to improve prefetching performance, this work concentrates in the prefetching engine and proposes the Prediction at Prefetch (P@P) technique. This paper explains how a prefetching technique can be extended to include our P@P proposal on real world conditions without changes in the web architecture or HTTP protocol. To show how this proposal can improve prefetching performance an extensive performance evaluation study has been done and the results show that P@P can…
Augmenting CASE tools with hypertext: Desired functionality and implementation issues
1997
Information systems have become bigger and more complex as their support has expanded to cover larger business domains, communication and work. At the same time technical design options such as client/server architectures and graphical user interfaces have increased the size and complexity of applications. In addition, pressures to build better systems more quickly have motivated the use of integrated design environments, such as CASE. Several integration approaches such as process modeling, frameworks and hypertext technology have been proposed. Of these we consider the least analyzed, hypertext technology, in this paper. Because of the novelty of hypertext in CASE there are several unreso…
Self-Regulation and Link Selection Strategies in Hypertext
2010
This article explores the role of self-regulation in strategies that readers use to decide the order in which to read the different sections of a hypertext. This study explored 3 main strategies for link selection based on (a) link screen position, (b) link interest, and (c) the semantic relation of a link with the section just read. This study followed Winne's (1995, 2001) model of self-regulated learning to try to explain why some readers select hyperlinks based on strategies that lead to lower levels of comprehension (i.e., screen position and personal interest). Results from 2 studies revealed that readers with low prior knowledge base their decisions on what to read next on a default s…
Aristotelian Cross-References Network
2014
In this paper, I suggest to use the cross-references that can be found in Aristotle's works as hyperlinks. Drawing a map of Aristotle's works on the basis of these cross-references, it will possible to build an interface to navigate inside Aristotle's corpus and to reconstruct a network of the connections among several layers of his philosophical and scientific project.
Technology for supporting web information search and learning in Sign Language
2009
Sign Languages (SL) are underrepresented in the digital world, which contributes to the digital divide for the Deaf Community. In this paper, our goal is twofold: (1) to review the implications of current SL generation technologies for two key user web tasks, information search and learning and (2) to propose a taxonomy of the technical and functional dimensions for categorizing those technologies. The review reveals that although contents can currently be portrayed in SL by means of videos of human signers or avatars, the debate about how bilingual (text and SL) versus SL-only websites affect signers' comprehension of hypertext content emerges as an unresolved issue in need of further empi…
Reading skills and children’s navigation strategies in hypertext
2011
Prior research has identified two important navigation strategies that have a clear impact on hypertext comprehension: link selection and overview processing strategies. The first relate to the order in which students select hyperlinks while trying to comprehend a hypertext, whereas the second relate to when and for how long students process navigation overviews, a text device that conveys the text structure by displaying sections, titles and their relations. Most prior research in navigation strategies has been conducted with undergraduate students. We extend prior research by exploring the navigation strategies used by sixth-graders while reading a hypermedia system. We also investigate h…
Children's Reading of Printed Text and Hypertext with Navigation Overviews: The Role of Comprehension, Sustained Attention, and Visuo-Spatial Abiliti…
2012
Hypertexts include new structural features, such as navigable graphical overviews, that dramatically change the way students interact with texts. Nevertheless, at school students traditionally practice literacy skills appropriate for reading and comprehending printed texts. We explored the possibility that those skills might not be the same as the ones required to master hypertext reading. Specifically, we tested the hypothesis that hypertext structural features, such as navigable graphical overviews, might scaffold students with low comprehension and sustained-attention abilities, but demand higher involvement of visuo-spatial skills. Results from a group of 6th-grade students only partia…
Does collaborative hypertext support better engagement in learning of the basics in informatics?
1997
Hypertext is a powerful cognitive tool supporting knowledge construction. We organized two courses about the basics in informatics using collaborative hypertext (experimental groups) based on the hyperbooks built by the students participating in the courses. Simultaneously, we ran two courses without collaborative hypertext (control groups). The study found that collaborative hypertext affects motivation equally regarding most themes of the basics in informatics.The result reflects the need for traditional uncomputerized learning methods in the basics of informatics or the need to concentrate on improving the truthfulness of hypertext-based learning. However, some students may benefit from …
Who Benefits from WWW Presentation in the Basics of Informatics?
2011
This paper describes the use of WWW-based guided tours as a complementary addition to conventional lectures in the basics of informatics. Learning can be promoted in the spirit of constructivism, situated action, and cognitive flexibility when organizing a WWW coursework. We analyze the benefit of an optional coursework, including the use of guided tours and the use of search engines and directories on the WWW. This paper presents who benefits and who does not benefit from our optional coursework. The analysis is based on the background information and prior computer experience of the students, as well as pre and post tests. The study found that our WWW-based coursework suits best for femal…
A study of intermittency in Hadronic Z$^0$ Decays
1990
The correlations in rapidity in hadron production from e+e- annihilation near the Z0 resonance were studied by means of the method of factorial moments, using data taken with the DELPHI detector at LEP. The parton shower hadronization model was found to be in quantitative agreement with the data, in contrast with previous results at lower energies. © 1990.
