    Abstract
    Describes the concept of a proxy based information classification and filtering utility, named Web Assistant. On the behalf of users a private view of the WWW is generated based on a previously determined profile. This profile is created by monitoring the user anf group activities when browsing WWW pages. Additional features are integrated to allow for easy interoperability workgroups with similar project interests, maintain personal and common hotlists with automatic modification checks and a sophisticated search engine front-end

    Abstract
    Four focus groups were held with young Web users (10 to 13 years of age) to explore design criteria for Web portals. The focus group participants commented upon four existing portals designed with young users in mind: Ask Jeeves for Kids, KidsClick, Lycos Zone, and Yahooligans! This article reports their first impressions on using these portals, their likes and dislikes, and their suggestions for improvements. Design criteria for children's Web portals are elaborated based upon these comments under four headings: portal goals, visual design, information architecture, and personalization. An ideal portal should cater for both educational and entertainment needs, use attractive screen designs based especially on effective use of color, graphics, and animation, provide both keyword search facilities and browsable subject categories, and allow individual user personalization in areas such as color and graphics

    "Die Suchmaschine Google gilt oft als der beste Weg, um schnell etwas im Internet zu finden. Das war einmal, behauptet Apostolos Gerasoulis, jetzt gebe es www.teoma. com. "Wir sind die nächste Generation der Suchmaschinen", verspricht der Mathematikprofessor. Die Web-Sites von Google und Teoma sind ähnlich aufgemacht. Beide bieten eine weitgehend weiße Startseite mit wenigen, klaren Farben. Beide Suchmaschinen benutzen bei ihrer Arbeit zur Analyse der Anfragen einen komplizierten Algorithmus. Teoma hält den eigenen Ansatz aber für besser, weil dabei das Internet in Gruppen von Online-Gemeinschaften unterteilt wird. Dies liefere bessere Ergebnisse und erlaube eine nützlichere Auswahl. Zu einem Suchbegriff erscheinen bei Teoma zuerst links oben die bezahlten Verweise, darunter dann' alle anderen gefundenen Web-Seiten. Rechts erscheinen Vorschläge zur Verfeinerung der Suchanfrage, darunter manchmal Links von "Experten und Enthusiasten". Diese qualifizierten Antworten sind eine der Stärken, mit denen Teoma wuchern möchte. Sie sind besonders für Anfänger nützlich, die nach allgemeinen Themen wie Afrika" oder "Fußball" suchen. Allerdings könnte dieser Ergebnisdienst Nutzer auch überfordern, gerade wenn sie an das einfache Google gewöhnt seien, kritsiert Rob Lancaster von der Yankee Group."

    Abstract
    Search engine users typically engage in multiquery sessions in their quest to fulfill their information needs. Despite a plethora of research findings suggesting that a significant group of users look for information within a specific geographical scope, existing reformulation studies lack a focused analysis of how users reformulate geographic queries. This study comprehensively investigates the ways in which users reformulate such needs in an attempt to fill this gap in the literature. Reformulated sessions were sampled from a query log of a major search engine to extract 2,400 entries that were manually inspected to filter geo sessions. This filter identified 471 search sessions that included geographical intent, and these sessions were analyzed quantitatively and qualitatively. The results revealed that one in five of the users who reformulated their queries were looking for geographically related information. They reformulated their queries by changing the content of the query rather than the structure. Users were not following a unified sequence of modifications and instead performed a single reformulation action. However, in some cases it was possible to anticipate their next move. A number of tasks in geo modifications were identified, including standard, multi-needs, multi-places, and hybrid approaches. The research concludes that it is important to specialize query reformulation studies to focus on particular query types rather than generically analyzing them, as it is apparent that geographic queries have their special reformulation characteristics.

    Abstract
    Current user interfaces for textual database searching leave much to be desired: individually, they are often confusing, and as a group, they are seriously inconsistent. We propose a four- phase framework for user-interface design: the framework provides common structure and terminology for searching while preserving the distinct features of individual collections and search mechanisms. Users will benefit from faster learning, increased comprehension, and better control, leading to more effective searches and higher satisfaction.

    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
