From web 1.0 to web 4.0

2014

The Internet is active and very dynamic. It has enabled an unprecedented evolution in telematics and information systems, and in turn a global revolution in the use of technology and digital citizenry. Although many see the technologies that have driven this revolution as inventions of the past 1 to 2 decades, quite a few had their genesis before the Internet became mainstream. In exploring the history of the Internet, we see how it has facilitated innovations across all areas of technology and social life, and with a little imagination are perhaps able to get a glimpse of what is to come. A lot of technologies related to the Web environment have emerged in this area: Blogs, Wikis, Social N…

Following the WCAG 2.0 techniques: Experiences from designing a WCAG 2.0 checking tool

2012

Published version of a chapter in the book: Computers Helping People with Special Needs. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-31522-0_63 This paper presents a conceptual analysis of how the Web Content Accessibility Guidelines (WCAG) 2.0 and its accompanying documents can be used as a basis for the implementation of an automatic checking tool and the definition of a web accessibility metric. There are two major issues that need to be resolved to derive valid and reliable conclusions from the output of individual tests. First, the relationship of Sufficient Techniques and Common Failures has to be taken into account. Second, the logical combination of the…

Web Traffic Modeling for E-Commerce Web Server System

2009

The paper concerns a problem of the e-commerce Web server system performance evaluation through simulation experiments, especially a problem of modeling a representative stream of user requests at the input of such system. Motivated by a need of a benchmarking tool for the Business-to-Consumer (B2C) environment we discuss a workload model typical of such Web sites and also a model of a multi-tiered e-commerce Web server system. A simulation tool in which the proposed models have been implemented is briefly talked over and some experimental results on the Web system performance in terms of traditional and business performance measures are presented.

Search Interfaces and Learning about Controversial Topics

2019

Search engine results pages (SERPs) are a frequent gateway to Internet content. Prior research has extensively documented strong effects of SERPs (e.g. rank order or the spatial distribution of the results) on users' attention to and selection of particular Web pages [1,2]. In the context of Web search, a common user behavior is the 'top link' or 'Google trust' heuristic, that is, the inspection and selection of only the first few search results presented by the search engine, without evaluating all other search results available. This heuristic behavior allows users to find information in an efficient way, as search engines tend to provide relevant documents on top of the list, especially …

Personal data in a large digital library

2000

The RePEc Economics library offers the largest distributed source of freely downloadable scientific research reports in the world. RePEc also contains details about Economics institutions, publication outlets and people working in the field. All this data forms a large relational dataset. In this paper we describe HoPEc, a system that allows to implement access control records personal data within RePEc. The bulk of these records describe the authors of documents. These records are maintained by the authors themselves. We discuss the technical and social aspects of this system.

Semantic Annotation and Retrieval of Services in the Cloud

2013

Recently, the economy has taken a downturn, which has forced many companies to reduce their costs in IT. This fact has, conversely, benefited the adoption of innovative computing models such as cloud computing, which allow businesses to reduce their fixed IT costs through outsourcing. As the number of cloud services available on the Internet grows, it is more and more difficult for companies to find those that can meet their needs. Under these circumstances, enabling a semantically-enriched search engine for cloud solutions can be a major breakthrough. In this paper, we present a fully-fledged platform based on semantics that (1) assist in generating a semantic description of cloud services…

The Web Computer and Its Operating System: A New Approach for Creating Web Applications

2019

Web applications require not only more sophisticated infrastructure than traditional single-PC applications, but also a different way of thinking, where network-specific aspects have to be considered. In this paper, we introduce the web computer concept, which factors out network-related issues and provides an illusion of a single computer with directly attached CPUs, memory, and I/O devices. By assuming the web computer and its open operating system (webAppOS) as a target platform for web applications, developers can preserve the same level of thinking as when developing classical desktop applications. With this approach, which corresponds to the physiology of the human brain, web applicat…
