Abstract

This paper aims to review the fiercely discussed question of whether the ranking of Wikipedia articles in search engines is justified by the quality of the articles. After an overview of current research on information quality in Wikipedia, a summary of the extended discussion on the quality of encyclopedic entries in general is given. On this basis, a heuristic method for evaluating Wikipedia entries is developed and applied to Wikipedia articles that scored highly in a search engine retrieval effectiveness test and compared with the relevance judgment of jurors. In all search engines tested, Wikipedia results are unanimously judged better by the jurors than other results on the corresponding results position. Relevance judgments often roughly correspond with the results from the heuristic evaluation. Cases in which high relevance judgments are not in accordance with the comparatively low score from the heuristic evaluation are interpreted as an indicator of a high degree of trust in Wikipedia. One of the systemic shortcomings of Wikipedia lies in its necessarily incoherent user model. A further tuning of the suggested criteria catalog, for instance, the different weighing of the supplied criteria, could serve as a starting point for a user model differentiated evaluation of Wikipedia articles. Approved methods of quality evaluation of reference works are applied to Wikipedia articles and integrated with the question of search engine evaluation.

Abstract

In diesem Kapitel wird ein Überblick über bestehende semantische Suchmaschinen gegeben. Insgesamt werden 95 solcher Suchdienste identifiziert und im Rahmen einer Inhaltsanalyse verglichen. Es kann festgestellt werden, dass die Semantische Suche sich wesentlich von den im Rahmen des Semantic Web propagierten Technologien unterscheidet und Semantik in den betrachteten Suchmaschinen weiter zu fassen ist. Die betrachteten Suchmaschinen werden in ein Stufenmodell, welches nach dem Grad der Semantik unterscheidet, eingeordnet. Das Kapitel schließt mit 8 Thesen zum aktuellen Stand der semantischen Suche.

Abstract

Am Beispiel der Kooperation zwischen dem Department Information der HAW Hamburg und dem Landschaftsverband Rheinland in einem Thesaurusprojekt zur kollaborativen Erschließung von Fachinformationen des kulturellen Erbes wird gezeigt, wie unter den begrenzten Möglichkeiten der informations- und bibliothekswissenschaftlichen Fachbereiche an Fachhochschulen Forschungs- und Entwicklungsvorhaben in enger Kooperation mit der Praxis umgesetzt werden können. Es wird dargestellt, wie Domänenexperten und Informationsspezialisten beim Aufbau und der Pflege eines kontrollierten Fachvokabulars erfolgreich kooperieren können, aber auch welche Schwierigkeiten eine solche Zusammenarbeit zu überwinden hat.
