    Abstract
    The use of non-English Web search engines has been prevalent. Given the popularity of Chinese Web searching and the unique characteristics of Chinese language, it is imperative to conduct studies with focuses on the analysis of Chinese Web search queries. In this paper, we report our research on the character usage of Chinese search logs from a Web search engine in Hong Kong. By examining the distribution of search query terms, we found that users tended to use more diversified terms and that the usage of characters in search queries was quite different from the character usage of general online information in Chinese. After studying the Zipf distribution of n-grams with different values of n, we found that the curve of unigram is the most curved one of all while the bigram curve follows the Zipf distribution best, and that the curves of n-grams with larger n (n = 3-6) had similar structures with ?-values in the range of 0.66-0.86. The distribution of combined n-grams was also studied. All the analyses are performed on the data both before and after the removal of function terms and incomplete terms and similar findings are revealed. We believe the findings from this study have provided some insights into further research in non-English Web searching and will assist in the design of more effective Chinese Web search engines.

    Abstract
    Die Informationspraxis von Studierenden und Wissenschaftler(inne)n im Kontext wissenschaftlicher Bibliotheken wandelt sich unter den Vorzeichen der digitalen Informationswelt tiefgreifend, weist jedoch nicht nur in Richtung auf den aktiven Web 2.0-Nutzer bzw. den "Internetnutzer von morgen", wie es bisweilen den Anschein hat. Die durch die komplexen Anforderungen neuer Studiengänge stark beanspruchten Studierenden wie auch die unter hohem Konkurrenz- und Erfolgsdruck forschenden Wissenschaftler(inne)n benötigen vielmehr die Bibliotheken mit ihren professionellen Services und in ihrer Rolle als "Navigatoren im Wissensozean" mehr denn je. Bei ihren Hauptnutzungsgruppen - Studierenden und Wissenschaftler(inne)n - genießen die wissenschaftlichen Bibliotheken gerade wegen ihrer verlässlichen, auf Kontinuität angelegten Kernaufgaben der Beschaffung (auch Lizenzierung) der für Studium und Forschung wesentlichen Medien und Ressourcen, deren professioneller Erschließung und Bereitstellung, sodann wegen der Unterstützung des wissenschaftlichen Publizierens, wegen ihres Angebots bedarfsorientierter (Fach-) Informationsdienste und ihrer auf die konkreten Arbeits- und Lernbedürfnisse abgestimmten Informationsinfrastrukturen nach wie vor hohe Reputation. Dies belegen die Befunde nahezu aller wesentlichen neueren Nutzerstudien im deutschsprachigen Raum wie auch langjährige Erfahrungen im Zusammenhang mit Kursen zur Vermittlung von Informationskompetenz. Der Vortrag thematisiert die Bedeutung bibliothekarisch gestalteter Informationsarchitekturen für professionelle wissenschaftliche Informationsarbeit im Licht des empirisch nachweisbaren Nutzerbedarfs und Informationsverhaltens.

    Abstract
    In the first part of this article the author defines the n-overlap vector whose coordinates consist of the fraction of the objects (e.g., books, N-grams, etc.) that belong to 1, 2, , n sets (more generally: families) (e.g., libraries, databases, etc.). With the aid of the Lorenz concentration theory, a theory of n-overlap similarity is conceived together with corresponding measures, such as the generalized Jaccard index (generalizing the well-known Jaccard index in case n 5 2). Next, the distributional form of the n-overlap vector is determined assuming certain distributions of the object's and of the set (family) sizes. In this section the decreasing power law and decreasing exponential distribution is explained for the n-overlap vector. Both item (token) n-overlap and source (type) n-overlap are studied. The n-overlap properties of objects indexed by a hierarchical system (e.g., books indexed by numbers from a UDC or Dewey system or by N-grams) are presented in the final section. The author shows how the results given in the previous section can be applied as well as how the Lorenz order of the n-overlap vector is respected by an increase or a decrease of the level of refinement in the hierarchical system (e.g., the value N in N-grams).

    Abstract
    The need for effective identity matching systems has led to extensive research in the area of name search. For the most part, such work has been limited to English and other Latin-based languages. Consequently, algorithms such as Soundex and n-gram matching are of limited utility for languages such as Arabic, which has vastly different morphologic features that rely heavily on phonetic information. The dearth of work in this field is partly caused by the lack of standardized test data. Consequently, we have built a collection of 7,939 Arabic names, along with 50 training queries and 111 test queries. We use this collection to evaluate a variety of algorithms, including a derivative of Soundex tailored to Arabic (ASOUNDEX), measuring effectiveness by using standard information retrieval measures. Our results show an improvement of 70% over existing approaches.
