    Abstract
    Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht

    Abstract
    Proceedings of the llth TREC-conference held in Gaithersburg, Maryland (USA), November 19-22, 2002. Aim of the conference was discussion an retrieval and related information-seeking tasks for large test collection. 93 research groups used different techniques, for information retrieval from the same large database. This procedure makes it possible to compare the results. The tasks are: Cross-language searching, filtering, interactive searching, searching for novelty, question answering, searching for video shots, and Web searching.

    Rez. in: Information - Wissenschaft und Praxis 57(2006) H.5, S.290-291 (C. Schindler): "Weniger als ein Jahr nach dem "Vierten Hildesheimer Evaluierungs- und Retrievalworkshop" (HIER 2005) im Juli 2005 ist der dazugehörige Tagungsband erschienen. Eingeladen hatte die Hildesheimer Informationswissenschaft um ihre Forschungsergebnisse und die einiger externer Experten zum Thema Information Retrieval einem Fachpublikum zu präsentieren und zur Diskussion zu stellen. Unter dem Titel "Effektive Information Retrieval Verfahren in Theorie und Praxis" sind nahezu sämtliche Beiträge des Workshops in dem nun erschienenen, 15 Beiträge umfassenden Band gesammelt. Mit dem Schwerpunkt Information Retrieval (IR) wird ein Teilgebiet der Informationswissenschaft vorgestellt, das schon immer im Zentrum informationswissenschaftlicher Forschung steht. Ob durch den Leistungsanstieg von Prozessoren und Speichermedien, durch die Verbreitung des Internet über nationale Grenzen hinweg oder durch den stetigen Anstieg der Wissensproduktion, festzuhalten ist, dass in einer zunehmend wechselseitig vernetzten Welt die Orientierung und das Auffinden von Dokumenten in großen Wissensbeständen zu einer zentralen Herausforderung geworden sind. Aktuelle Verfahrensweisen zu diesem Thema, dem Information Retrieval, präsentiert der neue Band anhand von praxisbezogenen Projekten und theoretischen Diskussionen. Das Kernthema Information Retrieval wird in dem Sammelband in die Bereiche Retrieval-Systeme, Digitale Bibliothek, Evaluierung und Multilinguale Systeme untergliedert. Die Artikel der einzelnen Sektionen sind insgesamt recht heterogen und bieten daher keine Überschneidungen inhaltlicher Art. Jedoch ist eine vollkommene thematische Abdeckung der unterschiedlichen Bereiche ebenfalls nicht gegeben, was bei der Präsentation von Forschungsergebnissen eines Institutes und seiner Kooperationspartner auch nur bedingt erwartet werden kann. So lässt sich sowohl in der Gliederung als auch in den einzelnen Beiträgen eine thematische Verdichtung erkennen, die das spezielle Profil und die Besonderheit der Hildesheimer Informationswissenschaft im Feld des Information Retrieval wiedergibt. Teil davon ist die mehrsprachige und interdisziplinäre Ausrichtung, die die Schnittstellen zwischen Informationswissenschaft, Sprachwissenschaft und Informatik in ihrer praxisbezogenen und internationalen Forschung fokussiert.

    Abstract
    Whereas in language words of high frequency are generally associated with low content [Bookstein, A., & Swanson, D. (1974). Probabilistic models for automatic indexing. Journal of the American Society of Information Science, 25(5), 312-318; Damerau, F. J. (1965). An experiment in automatic indexing. American Documentation, 16, 283-289; Harter, S. P. (1974). A probabilistic approach to automatic keyword indexing. PhD thesis, University of Chicago; Sparck-Jones, K. (1972). A statistical interpretation of term specificity and its application in retrieval. Journal of Documentation, 28, 11-21; Yu, C., & Salton, G. (1976). Precision weighting - an effective automatic indexing method. Journal of the Association for Computer Machinery (ACM), 23(1), 76-88], shallow syntactic fragments of high frequency generally correspond to lexical fragments of high content [Lioma, C., & Ounis, I. (2006). Examining the content load of part of speech blocks for information retrieval. In Proceedings of the international committee on computational linguistics and the association for computational linguistics (COLING/ACL 2006), Sydney, Australia]. We implement this finding to Information Retrieval, as follows. We present a novel automatic query reformulation technique, which is based on shallow syntactic evidence induced from various language samples, and used to enhance the performance of an Information Retrieval system. Firstly, we draw shallow syntactic evidence from language samples of varying size, and compare the effect of language sample size upon retrieval performance, when using our syntactically-based query reformulation (SQR) technique. Secondly, we compare SQR to a state-of-the-art probabilistic pseudo-relevance feedback technique. Additionally, we combine both techniques and evaluate their compatibility. We evaluate our proposed technique across two standard Text REtrieval Conference (TREC) English test collections, and three statistically different weighting models. Experimental results suggest that SQR markedly enhances retrieval performance, and is at least comparable to pseudo-relevance feedback. Notably, the combination of SQR and pseudo-relevance feedback further enhances retrieval performance considerably. These collective experimental results confirm the tenet that high frequency shallow syntactic fragments correspond to content-bearing lexical fragments.
