    Abstract
    The authors review a log of billions of Web queries that constituted the total query traffic for a 6-month period of a general-purpose commercial Web search service. Previously, query logs were studied from a single, cumulative view. In contrast, this study builds on the authors' previous work, which showed changes in popularity and uniqueness of topically categorized queries across the hours in a day. To further their analysis, they examine query traffic on a daily, weekly, and monthly basis by matching it against lists of queries that have been topically precategorized by human editors. These lists represent 13% of the query traffic. They show that query traffic from particular topical categories differs both from the query stream as a whole and from other categories. Additionally, they show that certain categories of queries trend differently over varying periods. The authors key contribution is twofold: They outline a method for studying both the static and topical properties of a very large query log over varying periods, and they identify and examine topical trends that may provide valuable insight for improving both retrieval effectiveness and efficiency.

    Abstract
    The application of clustering to Web search engine technology is a novel approach that offers structure to the information deluge often faced by Web searchers. Clustering methods have been well studied in research labs; however, real user searching with clustering systems in operational Web environments is not well understood. This article reports on results from a transaction log analysis of Vivisimo.com, which is a Web meta-search engine that dynamically clusters users' search results. A transaction log analysis was conducted on 2-week's worth of data collected from March 28 to April 4 and April 25 to May 2, 2004, representing 100% of site traffic during these periods and 2,029,734 queries overall. The results show that the highest percentage of queries contained two terms. The highest percentage of search sessions contained one query and was less than 1 minute in duration. Almost half of user interactions with clusters consisted of displaying a cluster's result set, and a small percentage of interactions showed cluster tree expansion. Findings show that 11.1% of search sessions were multitasking searches, and there are a broad variety of search topics in multitasking search sessions. Other searching interactions and statistics on repeat users of the search engine are reported. These results provide insights into search characteristics with a cluster-based Web search engine and extend research into Web searching trends.

    "Es ist ein Start mit verschiedenen Schwächen: Der neue Google-Konkurrent "Wikia Search" verschreckt den User in seiner aktuellen Vor-abversion mit fehlerhaften Links, fehlenden Ergebnissen oder auch fragwürdigen Seitenbewertungen. Trotzdem bietet die neue Suchmaschine des Wikipedia-Gründers Jimmy Wales schon jetzt einen unschätzbaren Vorteil gegenüber dein Branchenprimus Google: Wikia Search legt den Nutzern offen, wie die Suchergebnisse zustande kommen. Sie setzt nämlich OpenSource-Programme ein - etwa den Webcrawler Grub. Dessen Algorithmen liegen für jedermann offen einsehbar im Web. Wikia Search fordert gar zum aktiven Mitmachen auf: Die Surfer können angezeigte Links bewerten Lind so die Rangfolge der Ergebnisse beeinflussen. Die Suchmaschine soll die Ergebnisse mit der Zeit besser nach Relevanz und Qualität sortieren, verspricht das Entwicklerteam. Derzeit speichert die Seite Bewertungen durch User jedoch noch nicht ab. Zusätzlich zeigt Wikia Search, passend zu den Suchbegriffen, jeweils einen kurzen Übersichtsartikel an, der allgemeine Informationen enthält. Sollte so ein Text noch fehlen, kann ganz einfach per Mausklick ein neues Dokument angelegt werden. Praktisch dabei: Jeder Nutzer hat die Möglichkeit, den Inhalt ohne Anmeldung zu bearbeiten und zu erweitern. Eine Alternative zur normalen Suche soll die »Whitelist« sein. Darin können User eine Art Webseiten-Kata-log anlegen, der für bessere Suchergebnisse sorgen soll. Die Idee einer offenen und nutzerorientierten Suchmaschine klingt vielversprechend - eine ernsthafte Konkurrenz für etablierte Suchmaschinen wie Google kann Wikia Search allerdings noch nicht sein. Denn die neue Websuche ist abhängig von der Community und ihrer Mitarbeit an dem Projekt. Dass so ein Ansatz funktionieren kann, hat die Online-Enzyklopädie Wikipedia immerhin gezeigt."

    Abstract
    The article employs deep log analysis (DLA) techniques, a more sophisticated form of transaction log analysis, to demonstrate what usage data can disclose about information seeking behaviour of virtual scholars - academics, and researchers. DLA works with the raw server log data, not the processed, pre-defined and selective data provided by journal publishers. It can generate types of analysis that are not generally available via proprietary web logging software because the software filters out relevant data and makes unhelpful assumptions about the meaning of the data. DLA also enables usage data to be associated with search/navigational and/or user demographic data, hence the name 'deep'. In this connection the usage of two digital journal libraries, those of EmeraldInsight, and Blackwell Synergy are investigated. The information seeking behaviour of nearly three million users is analyzed in respect to the extent to which they penetrate the site, the number of visits made, as well as the type of items and content they view. The users are broken down by occupation, place of work, type of subscriber ("Big Deal", non-subscriber, etc.), geographical location, type of university (old and new), referrer link used, and number of items viewed in a session.

    Die technische Entwicklung hat dazu geführt, dass man die gegenwärtige Zeit auch gerne als Zeitalter der Kommunikation bezeichnet. Von den ersten Informations-Fernübertragungen per Rauchzeichen bis zur globalen Videotelefonie ist ein langer Weg, der die sog. Globalisierung erst ermöglichte. Im folgenden sollen einige stationen Revue passiert werden lassen. Jedoch ist Kommunikation nicht nur elektronischer Datentransfer, wie der anschließende Beitrag verdeutlicht

    Abstract
    In this paper, we define and present a comprehensive classification of user intent for Web searching. The classification consists of three hierarchical levels of informational, navigational, and transactional intent. After deriving attributes of each, we then developed a software application that automatically classified queries using a Web search engine log of over a million and a half queries submitted by several hundred thousand users. Our findings show that more than 80% of Web queries are informational in nature, with about 10% each being navigational and transactional. In order to validate the accuracy of our algorithm, we manually coded 400 queries and compared the results from this manual classification to the results determined by the automated method. This comparison showed that the automatic classification has an accuracy of 74%. Of the remaining 25% of the queries, the user intent is vague or multi-faceted, pointing to the need for probabilistic classification. We discuss how search engines can use knowledge of user intent to provide more targeted and relevant results in Web searching.

    Abstract
    Automatic classification of Web pages is an effective way to organise the vast amount of information and to assist in retrieving relevant information from the Internet. Although many automatic classification systems have been proposed, most of them ignore the conflict between the fixed number of categories and the growing number of Web pages being added into the systems. They also require searching through all existing categories to make any classification. This article proposes a dynamic and hierarchical classification system that is capable of adding new categories as required, organising the Web pages into a tree structure, and classifying Web pages by searching through only one path of the tree. The proposed single-path search technique reduces the search complexity from (n) to (log(n)). Test results show that the system improves the accuracy of classification by 6 percent in comparison to related systems. The dynamic-category expansion technique also achieves satisfying results for adding new categories into the system as required.

    Abstract
    This paper proposes an effective term suggestion approach to interactive Web search. Conventional approaches to making term suggestions involve extracting co-occurring keyterms from highly ranked retrieved documents. Such approaches must deal with term extraction difficulties and interference from irrelevant documents, and, more importantly, have difficulty extracting terms that are conceptually related but do not frequently co-occur in documents. In this paper, we present a new, effective log-based approach to relevant term extraction and term suggestion. Using this approach, the relevant terms suggested for a user query are those that cooccur in similar query sessions from search engine logs, rather than in the retrieved documents. In addition, the suggested terms in each interactive search step can be organized according to its relevance to the entire query session, rather than to the most recent single query as in conventional approaches. The proposed approach was tested using a proxy server log containing about two million query transactions submitted to search engines in Taiwan. The obtained experimental results show that the proposed approach can provide organized and highly relevant terms, and can exploit the contextual information in a user's query session to make more effective suggestions.

    Abstract
    In diesem Kapitel werden Anwendungsgebiete und Ansätze für die semantische Beschreibung von Web Services behandelt. Bestehende Web Service Technologien leisten einen entscheidenden Beitrag zur Entwicklung verteilter Anwendungen dadurch, dass weithin akzeptierte Standards vorliegen, die die Kommunikation zwischen Anwendungen bestimmen und womit deren Kombination zu komplexeren Einheiten ermöglicht wird. Automatisierte Mechanismen zum Auffinden geeigneter Web Services und deren Komposition dagegen werden von bestehenden Technologien in vergleichsweise geringem Maß unterstützt. Ähnlich wie bei der Annotation statischer Daten im "Semantic Web" setzen Forschung und Industrie große Hoffnungen in die semantische Beschreibung von Web Services zur weitgehenden Automatisierung dieser Aufgaben.

    Abstract
    A large number of studies have investigated the transaction log of general-purpose search engines such as Excite and AItaVista, but few studies have reported an the analysis of search logs for search engines that are limited to particular Web sites, namely, Web site search engines. In this article, we report our research an analyzing the search logs of the search engine of the Utah state government Web site. Our results show that some statistics, such as the number of search terms per query, of Web users are the same for general-purpose search engines and Web site search engines, but others, such as the search topics and the terms used, are considerably different. Possible reasons for the differences include the focused domain of Web site search engines and users' different information needs. The findings are useful for Web site developers to improve the performance of their services provided an the Web and for researchers to conduct further research in this area. The analysis also can be applied in e-government research by investigating how information should be delivered to users in government Web sites.

    Abstract
    Trotz des weit gefassten Zeitrahmens brachte die Konferenz wichtige Aspekte der zukünftigen Entwicklungen deutlich zum Ausdruck. Es zeigte sich klar, dass es den generellen Nutzer nicht gibt und eine gute Kommunikation und Differenzierung für verschiedene Bewertungen dringend erforderlich ist. Professionelle Rechercheure sind für qualifizierte Analysen insbesondere im Patentbereich unumgänglich. Immer stärker wird nach der Verbindung unterschiedlicher Datenformate und Fachbereiche verlangt, die damit verbundenen Probleme insbesondere bei Verarbeitung und Archivierung sind erkannt und werden bearbeitet. Die Einbindung von Webinformationen hat sich IBM mit dem Web Fountain Projekt auf die Fahnen geschrieben, weist aber gleichzeitig darauf hin, dass die Auswertung großer Datenmengen durch Text Mining noch nicht ausgereift sei. Geschäftsmodelle, die sich für die Zukunft eignen sind noch nicht erkennbar. Nach wie vor wird auf das Anzeigengeschäft abgehoben. Die Open Access Initiative wird als unumgänglich angesehen, doch eine enge Zusammenarbeit mit den Verlegern wird empfohlen, um Schaden für Wissenschaft und Forschung durch unausgereiftes Vorgehen zu vermeiden.

    Abstract
    The article presents the search situation transition (SST) method for analysing Web information search (WIS) processes. The idea of the method is to analyse searching behaviour, the process, in detail and connect both the searchers' actions (captured in a log) and his/her intentions and goals, which log analysis never captures. On the other hand, ex post factor surveys, while popular in WIS research, cannot capture the actual search processes. The method is presented through three facets: its domain, its procedure, and its justification. The method's domain is presented in the form of a conceptual framework which maps five central categories that influence WIS processes; the searcher, the social/organisational environment, the work task, the search task, and the process itself. The method's procedure includes various techniques for data collection and analysis. The article presents examples from real WIS processes and shows how the method can be used to identify the interplay of the categories during the processes. It is shown that the method presents a new approach in information seeking and retrieval by focusing on the search process as a phenomenon and by explicating how different information seeking factors directly affect the search process.

    Abstract
    When studying how ordinary Web users interact with Web search engines, researchers tend to either treat the users as a homogeneous group or group them according to search experience. Neither approach is sufficient, we argue, to capture the variety in behavior that is known to exist among searchers. By applying automatic clustering technique based on self-organizing maps to search engine log files from a corporate intranet, we show that users can be usefully separated into distinguishable segments based on their actual search behavior. Based on these segments, future tools for information seeking and retrieval can be targeted to specific segments rather than just made to fit the the average user. The exact number of clusters, and to some extent their characteristics, can be expected to vary between intranets, but our results indicate that some more generic groups may exist. In our study, a large group of users appeared to be fact seekers who would benefit from higher precision, a smaller group of users were more holistically oriented and would likely benefit from higher recall, and a third category of users seemed to constitute the knowledgeable users. These three groups may raise different design implications for search-tool developers.
