This is still impossible or unacceptably difficult on the World Wide Web. Yet, the Web cannot be replaced, given the amount of data and tools that rely on its basic protocols and languages. The vision presented here is of an evolution of the Web where, within the current framework of technologies and tools, every Web page can be edited and customized, links can be created, and collaboration can be set up. In a way, this is a vision of Xanadu coming to life again, but within the framework of Web technologies, styles and tools. It is a vision of the best possible approach to a fully writable, distributed hypertext system within the limitations of real-life protocols. This writable web, already partially available with blogs and wikis, is enhanced through the implementation of xanalogical storage to take care of individual changes to documents, and mechanisms for transclusions. IsaWiki, a client-server system being developed at the University of Bologna, is presented and shown to adhere to this vision of the writable web, and as being a first step in that direction.","PeriodicalId":236572,"journal":{"name":"J.

This paper presents Adaptive Personal Information Environment (a-PIE); a service-oriented framework using Open Hypermedia and Semantic Web technologies to provide an adaptive Web-based system. a-PIE models the information structures (data and links), context and behaviour as Fundamental Open Hypermedia Model (FOHM) structures which are manipulated by using the Auld Linky contextual link service. a-PIE provides an information environment that enables users to search an information space based on ontologically defined domain concepts. The users can add and manipulate (delete, comment, etc.) information of interests or part of an information structure in their information space, leaving the original published data or information structures unchanged. The a-PIE environment facilitates the shareability and reusability of knowledge according to users' requirements.","PeriodicalId":236572,"journal":{"name":"J. Digit.

{"title":"The connectivity sonar: detecting site functionality by structural patterns","authors":"E. Amitay, David Carmel, Adam Darlow, R. Lempel, A. Soffer","doi":"10.1145/900051.900060","DOIUrl":"https://doi.org/10.1145/900051.900060","url":null,"abstract":"Web sites today serve many different functions, such as corporate sites, search engines, e-stores, and so forth. As sites are created for different purposes, their structure and connectivity characteristics vary. However, this research argues that sites of similar role exhibit similar structural patterns, as the functionality of a site naturally induces a typical hyperlinked structure and typical connectivity patterns to and from the rest of the Web. Thus, the functionality of Web sites is reflected in a set of structural and connectivity-based features that form a typical signature. In this paper, we automatically categorize sites into eight distinct functional classes, and highlight several search-engine related applications that could make immediate use of such technology. We purposely limit our categorization algorithms by tapping connectivity and structural data alone, making no use of any content analysis whatsoever. When applying two classification algorithms to a set of 202 sites of the eight defined functional categories, the algorithms correctly classified between 54.5% and 59% of the sites. On some categories, the precision of the classification exceeded 85%. An additional result of this work indicates that the structural signature can be used to detect spam rings and mirror sites, by clustering sites with almost identical signatures.","PeriodicalId":236572,"journal":{"name":"J.

We will look at why horizontal links disappear, how to support horizontal navigation in modern hyper-courseware, and our earlier attempts to provide horizontal navigation in Web-based electronic textbooks. Here, we present map-based navigation - a new approach to support horizontal navigation in open corpus educational courseware that we are currently investigating. We will describe the mechanism behind this approach, present a system KnowledgeSea that implements this approach, and provide some results of a classroom study of this system.","PeriodicalId":236572,"journal":{"name":"J.
