A promise of new web-based technologies is that they provide learning opportunities for people distributed across the globe but who can participate across time and space in the same virtual learning community. How do they do it? In this paper we report on some of the experiences of a virtual learning community which has members from twenty-five countries across different time-zones and who comm...

This paper presents the issues involved in the application of agent technology to the management of Internet-based information. We present a general architecture, and discuss how this has been instantiated in two diierent applications. The rst system provides assistance to a user reading USENET news; identifying WorldWide Web pages which are of interest is the focus of the second implementation...

This paper introduces the LOD Laundromat Meta-Dataset, a continuously updated Meta-Dataset of the LOD Laundromat, tightly connected to the (re)published corresponding datasets which are crawled and cleaned by the LOD Laundromat [5]. The Meta-Dataset contains structural information for over 38 billion triples (and growing). While traditionally dataset meta-data is often not provided, incomplete,...

We present a method for matching target behaviors with solutions for achieving those behaviors. Called the Behavior Wizard, this method first classifies behavior change targets into one of 15 types. Later stages focus on triggers for the target behaviors and on relevant theories and techniques. This new approach to persuasive design, as well as the terminology we propose, can lead to insights i...

A collection of 3208 reported errors of Chinese words were analyzed. Among which, 7.2% involved rarely used character, and 98.4% were assigned common classifications of their causes by human subjects. In particular, 80% of the errors observed in writings of middle school students were related to the pronunciations and 30% were related to the compositions of words. Experimental results show that...

The growing volume and complexity of the World Wide Web creates a need for new forms of interaction with information. Spatial metaphors have been in the focus of interface research for a number of years. Recently, a related concept called spatialization has emerged as one possible strategy for dealing with modern information glut. However, the term remains ill-defined. We present a definition o...

The World-Wide-Web (WWW) offers a vast volume of information, more than ever any other medium has

Competitive intelligence (CI) is the selection, collection, interpretation and distribution of publicly held information that is strategically important to a firm. A substantial amount of this public information is accessible via the World Wide Web. This paper describes some of the difficulties in using this information resource for CI purposes, some of the solutions to these difficulties, and ...

This chapter is aimed at the study of quantitative measures of the relation between the dynamics of the Web, its structure, and the quality of Web pages. Quality is studied using different link-based metrics and considering their relationship with the structure of the Web and the last modification time of a page. We show that, as expected, Pagerank is biased against new pages, and we obtain inf...
