Ted Nelson's Xanadu remains an influential example of the way a world wide hypertext system should have been, allowing free access to hypertext pages for content customization and editing. 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.
Ted Nelson的Xanadu仍然是世界范围超文本系统的一个有影响力的例子，允许自由访问超文本页面进行内容定制和编辑。这在万维网上仍然是不可能或难以接受的困难。然而，考虑到依赖于其基本协议和语言的数据和工具的数量，Web是无法被取代的。这里展示的愿景是Web的进化，在当前的技术和工具框架内，每个Web页面都可以编辑和定制，可以创建链接，并且可以建立协作。在某种程度上，这是对世外桃源的再现，只不过是在Web技术、风格和工具的框架内。它是在现实协议的限制下实现完全可写的分布式超文本系统的最佳方法。这种可写的web已经部分地通过博客和wiki提供，通过实现类比存储来处理对文档的个别更改和传输机制得到增强。博洛尼亚大学(University of Bologna)正在开发的一个客户端-服务器系统IsaWiki，展示并展示了它坚持可写网络的愿景，并作为朝这个方向迈出的第一步。

In order to support knowledge workers throughout their task of searching, locating and manipulating information, a system that provides information suitable for a particular user's needs, and that is able to facilitate the sharing and reuse of knowledge is essential. 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.
为了支持知识工作者完成搜索、定位和操作信息的任务，提供适合特定用户需求的信息，并能够促进知识的共享和重用的系统是必不可少的。本文提出了自适应个人信息环境(Adaptive Personal Information Environment, a-PIE);一个面向服务的框架，使用开放超媒体和语义Web技术来提供自适应的基于Web的系统。a-PIE将信息结构(数据和链接)、上下文和行为建模为基本开放超媒体模型(FOHM)结构，这些结构通过使用old link上下文链接服务进行操作。a-PIE提供了一个信息环境，使用户能够基于本体定义的领域概念搜索信息空间。用户可以在自己的信息空间中添加和操作(删除、评论等)感兴趣的信息或信息结构的一部分，而不改变原来发布的数据或信息结构。a-PIE环境可根据用户需求促进知识的可共享性和可重用性。

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.

This paper discusses the problem of horizontal (non-hierarchical) navigation in modern educational courseware. 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.
