    Abstract
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    Abstract
    Reports on research into the information-seeking habits of primary schoolchildren conducted under operational conditions. Three workstations with Internet access were installed in a grade-six classroom in suburban Montreal. After a short introductory training session for the entire group followed by short individual sessions for each student, 53 students, working in small groups, used these workstations over a six-week period to seek information on the Web of relevance to a class project assigned by their teacher. The project dealt with the Winter Olympic Games (recently completed at that time). The student objective was to locate relevant information for a poster and an oral presentation on one of the sports represented at the Games. All screen activity was directly captured on videotape and group conversations at the workstation were audiotaped. Demographic and computer literacy information was gathered in a questionnaire. This paper presents a map of the information-seeking landscape based upon an analysis of the descriptive statistics gathered from the Web searches. It reveals that the novice users favored browsing over analytic search strategies, although they did show some sophistication in the construction of the latter. Online help was ignored. The children demonstrated a very high level of interactivity with the interface at the expense of thinking, planning and evaluating. This is a preliminary analysis of data which will subsequently be expanded by the inclusion of qualitative data

    Abstract
    The paper presents findings from a study of how knowledge workers use the Web to seek external information as part of their daily work. Thirty four users from seven companies took part in the study. Participants were mainly IT specialists, managers, and research/marketing/consulting staff working in organizations that included a large utility company, a major bank, and a consulting firm. Participants answered a detailed questionnaire and were interviewed individually in order to understand their information needs and information seeking preferences. A custom-developed WebTracker Software application was installed an each of their workplace PCs, and participants' Web-use activities were then recorded continuously during two-week periods. The WebTracker recorded how participants used the browser to seek information an the Web: it logged menu choices, button bar selections, and keystroke actions, allowing browsing and searching sequences to be reconstructed. In a second round of personal Interviews, participants recalled critical incidents of using information from the Web.Data from the two Interviews and the WebTracker logs constituted the database for analysis. Sixty one significant episodes of Information seeking were identified. A model was developed to describe the common repertoires of Information seeking that were observed. On one axis of the model, episodes were plotted according to the four scanning modes identified by Aguilar (1967), Weick and Daft (1983): undirected viewing, conditioned viewing, informal search, and formal search. Each mode is characterized by its own Information needs and Information seeking strategies. On the other axis of the model, episodes were plotted according to the occurence of one or more of the six categories of information seeking behaviors identified by Ellis (1989, 1990): starting, chaining, browsing, differentiating, monitoring, and extracting. The study suggests that a behavioral framework that relates motivations (Aguilar) and moves (Ellis) may be helpful in analysing patterns of Web-based Information seeking

    Abstract
    Search engine coverage relative to the estimated size of the publicly indexable web has decreased substantially since December 97, with no engine indexing more than about 16% of the estimated size of the publicly indexable web. (Note that many queries can be satisfied with a relatively small database). Search engines are typically more likely to index sites that have more links to them (more 'popular' sites). They are also typically more likely to index US sites than non-US sites (AltaVista is an exception), and more likely to index commercial sites than educational sites. Indexing of new or modified pages byjust one of the major search engines can take months. 83% of sites contain commercial content and 6% contain scientific or educational content. Only 1.5% of sites contain pornographic content. The publicly indexable web contains an estimated 800 million pages as of February 1999, encompassing about 15 terabytes of information or about 6 terabytes of text after removing HTML tags, comments, and extra whitespace. The simple HTML "keywords" and "description" metatags are only used on the homepages of 34% of sites. Only 0.3% of sites use the Dublin Core metadata standard.
