La casa ipertestuale. Le stanze e lo spazio-soglia
2008
Il saggio descrive i risultati di un'esperienza di seminario/workshop extracurriculare, svoltosi a Palermo nel 2005 (dal titolo: “Futura. Come abiteremo domani”). La metafora dell’ipertesto, spesso utilizzata da architetti, filosofi e urbanisti come metafora significativa per descrivere la condizione metropolitana contemporanea, risulta particolarmente efficace quale rappresentazione sintetica dell’idea di casa che abbiamo inteso indagare, per alcune sue qualità essenziali che trovano immediato riscontro nelle nuove modalità dell’abitare. All’interno del tema più generale della casa “ipertestuale”, la sperimentazione diretta dal Emanuele Palazzotto ha inteso esplorare alcune possibilità di …
Towards Advanced Visualisation Techniques in Case
1999
The complexity of information systems has resulted in more sophisticated CASE tools which integrate multifaceted design information using metamodeling and hypertext technologies. A designer can use this vast amount of tightly coupled information efficiently only if it is presented based on his needs and cognitive capabilities. In this paper we discuss how representations in CASE can be improved using advanced visualisation techniques.
Evaluation Framework of Hypertext Access for Program Comprehension Support
2008
Hypertext consists of text fragments connected by links enabling fast nonlinear browsing of the fragments. In case of program text there are many alternative ways to form the fragmentation and linkage. Transient hypertext is a general and well-grounded approach for offering capabilities to form versatile information access support for many kinds of central software maintenance activities. Transient hypertextual access structures (THASs) are data structures formed automatically based on situation dependent information needs of the users of program comprehension support tools. The approach has been implemented in HyperSoft system. It is aimed at supporting legacy software maintenance and comp…
Concept Maps for Comprehension and Navigation of Hypertexts
2013
Comprehension and learning with hypertexts are challenging due to the nonlinearity of such digital documents. Processing hypertexts may involve navigation and comprehension problems, leading learners to cognitive overhead. Concept maps have been added to hypertexts to reduce the cognitive requirements of navigation and comprehension. This chapter explores the literature to examine the effects of concept maps on navigation, comprehension, and learning from hypertexts. The literature review aims to elucidate how concept maps may contribute to processing hypertexts and under which conditions. In spite of the variability of concept maps used in hypertexts, some findings converge. Concept maps r…
How adolescents navigate Wikipedia to answer questions / ¿Cómo navegan los adolescentes en Wikipedia para contestar preguntas?
2015
AbstractIn one experiment, we explored how high school students use hyperlink relevance cues while they navigate to answer questions from hypertexts. Current evidence has shown that students may navigate by either performing a deep semantic analysis of the relationship between the question and the existing hyperlinks, or by matching words in the question to words in the hyperlink labels. We focused on how students combine both cues during navigation, and how comprehension skills relate to the use of such cues. Our study revealed that 14 year old students (N = 53) selected hyperlinks by relying to a similar degree on both word matching and semantic overlap. Furthermore, when there was a conf…
Scanning and deep processing of information in hypertext: an eye tracking and cued retrospective think-aloud study
2016
When students solve problems on the Internet, they have to find a balance between quickly scanning large sections of information in web pages and deeply processing those that are relevant for the task. We studied how high school students articulate scanning and deeper processing of information while answering questions using a Wikipedia document, and how their reading comprehension skills and the question type interact with these processes. By analyzing retrospective think-aloud protocols and eye-tracking measures, we found that scanning of information led to poor hypertext comprehension, while deep processing of information produced better performance, especially in location questions. Thi…
A Holonic Approach to Shakespeare: The Digital Reference System (DRS)
2012
Prefatory RemarksWhen hypertext was made available on the Internet after 1994 it shaped the concepts of public domain and free access. The web server and browsing system that Tim Berners-Lee and Robert Cailliau designed, determined the future digital, editorial and cultural developments for traditional audiences and digital natives alike. They quickly became the generalized interface tools and thus contributed to today's editorial standards. As they helped to create this innovative environment called the Internet, they also helped to establish many standards such as URL, URI, HTTP HTML or XML, which provided interoperability amongst different platforms and allowed internationalization.Shake…
La historia maleable. A propósito de Internet
2006
This essay attempts to assess the impact of the new technologies on the discipline of history. It starts from the assumption that the revolution in information technology has altered the way in which texts are transmitted, the medium in which they are made available, and the ways in which they are read. Moving on, this essay tries to evaluate how far it might affect other fundamental ideas. The changes are various. On the one hand, it could have an effect on the type of source, and to a degree on the critical method with which historians approach whatever type of document. On the other hand, it could also undermine the notion of authorship, not only because many of the new texts in existenc…

Experimental evaluation of hypertext access structures
2002
Transient hypertextual access structures (THASs) are temporary graphs formed automatically on the basis of the situation-dependent information needs of software engineers. The approach is implemented in the HyperSoft system, which is a hypertext-based software maintenance support tool. THASs highlight the relevant parts of the program and enable nonlinear browsing between them. The system also supports various graphical views whose elements are linked to the program text. This paper describes the effects of using these hypertextual structures in two separate experiments. The subjects of both experiments were computer science students (total N = 70). In both experiments, the subjects perform…
