Link ? Rot: URI Citation Durability in 10 Years of Ausweb Proceedings
Link? Rot. URI Citation Durability in 10 Years of AusWeb Proceedings. Link? Rot. URI Citation Durability in 10 Years of AusWeb Proceedings. Baden Hughes [HREF1], Research Fellow, Department of Computer Science and Software Engineering [HREF2] , The University of Melbourne [HREF3], Victoria, 3010, Australia. [email protected] Abstract The AusWeb conference has played a significant role in promoting and advancing research in web technologies in Australia over the last decade. Papers contributed to AusWeb are highly connected to the web in general, to digital libraries and to other conference sites in particular, owing to the publication of proceedings in HTML and full support for hyperlink based referencing. Authors have exploited this medium progressively more effectively, with the vast majority of references for AusWeb papers now being URIs as opposed to more traditional citation forms. The objective of this paper is to examine the reliability of URI citations in 10 years worth of AusWeb proceedings, particularly to determine the durability of such references, and to classify their causes of unavailability. Introduction The AusWeb conference has played a significant role in promoting and advancing research in web technologies in Australia over the last decade. In addition, the AusWeb forum serves as a point of reflection for practitioners engaged in web infrastructure, content and policy development; allowing the distillation of best practice in the management of web services particularly in higher educational institutions in the Australasian region. Papers contributed to AusWeb are highly connected to the web in general, to digital libraries and to other conference sites in particular, owing to the publication of proceedings in HTML and full support for hyperlink based referencing. -

Dhule-425405 Maharashtra, India Abstract : Online Social Networks (OSNs) have become fundamental parts of our online lives, and their popularity is increasing at a surprising rate every day. Growing popularity of Twitter has attracted the attention of attackers who attempt to manipulate the features provided by Twitter to gain some advantage, such as driving Twitter users to other websites that they post as short URLs (Uniform Resource Locators) in their tweets. Even short URLs are also used to avoid sharing overly long URLs and save limited text space in tweets. Significant numbers of URLs shared in the OSNs are shortened URLs. Despite of its potential benefits from genuine usage, attackers use shortened URLs to hide the malicious URLs, which direct users to malicious pages. Although, OSN service providers and URL shortening services utilize certain detection mechanisms to prevent malicious URLs from being shortened, research has found that they fail to do so effectively. In this paper, we developed mechanism to develop a machine learning classifier which detect malicious short URLs. And comparative analysis of detection rate with various classification algorithm, and but also with online detection on Virus Total. Index Terms - Online Social Networks, twitter, short URLs, malicious URLs, machine Learning, classification ________________________________________________________________________________________________________ I.

Tyler and Beth McNeil 615 Librarians and Link Rot: A Comparative Analysis with Some Methodological Considerations David C. Tyler and Beth McNeil abstract: The longevity of printed guides to resources on the web is a topic of some concern to all librarians. This paper attempts to determine whether guides created by specialist librarians perform better than randomly assembled lists of resources (assembled solely for the purpose of web studies), commercially created guides (‘Best of the web’-type publications), and guides prepared by specialists in library science and other fields. The paper also attempts to determine whether the characteristics of included web resources have an impact on guides’ longevity. Lastly, the paper addresses methodological issues of concern to this and similar studies. -
The Internet As Infrastructure
c h a p t e r 5 the internet as infrastructure c h r i s t i a n s a n d v i g In October 2010 the international web development community was thrown into disarray when it suddenly appeared that millions of common websites across the world would be required to satisfy the decency standards of Sharia, the religious law of Islam. 1 To understand how this unlikely situation came about requires that we know about the infrastructure of the Internet; it is a story about the collision of what is ultimately a variety of seemingly unrelated actors and actions, and this instance is comprehensible only aft er assembling all of them. Beginning with this example, this chapter will argue for the value of investi- gating the details of Internet infrastructure as a method of studying the Internet and society more generally. It will argue for the study of Internet Infrastructure and also for the value of considering the Internet infrastructurally, as a system foundational to other activities. A n i n f r a s t r u c t u r e e x a m p l e : f r o m the GET method to a woman’s bare arms Th e fi rst factors in this particular story about Sharia and the Web are technical. Over fi ft een years earlier, web server programmers on the www-talk mailing list anticipated that the Web would become more than just static web pages: they proposed a method for adding the information required for interactive web applications to the right side of a web page’s address or URL (this was called the “GET” smethod; see Robinson and Coar 2004 :33) . -
