    Abstract
    This article extends relevance theory (RT) from linguistic pragmatics into information retrieval. Using more than 50 retrieval experiments from the literature as examples, it applies RT to explain the frequency distributions of documents on relevance scales with three or more points. The scale points, which judges in experiments must consider in addition to queries and documents, are communications from researchers. In RT, the relevance of a communication varies directly with its cognitive effects and inversely with the effort of processing it. Researchers define and/or label the scale points to measure the cognitive effects of documents on judges. However, they apparently assume that all scale points as presented are equally easy for judges to process. Yet the notion that points cost variable effort explains fairly well the frequency distributions of judgments across them. By hypothesis, points that cost more effort are chosen by judges less frequently. Effort varies with the vagueness or strictness of scale-point labels and definitions. It is shown that vague scales tend to produce U- or V-shaped distributions, while strict scales tend to produce right-skewed distributions. These results reinforce the paper's more general argument that RT clarifies the concept of relevance in the dialogues of retrieval evaluation.

    Abstract
    Bei einem Vergleich unter Berücksichtigung aller verfügbaren Quellen gelang es mithilfe der MorphoSaurus-Technik - bei wesentlich geringerem Datenbestand - ähnlich gute Resul-tate zu erzielen, wie mit den Suchmaschinen Google oder Google Scholar. Die Ergebnisse der Evaluation lassen den Schluss zu, dass durch den MorphoSaurus-Ansatz die Leistungsfähigkeit von Google oder Google Scholar im Bereich der medizinischen Literatursuche durch eine Erweiterung der vorhandenen Datenbasis sogar deutlich übertroffen werden kann. Zusätzlich zu den Retrieval-Tests wurde eine Usability-Untersuchung der Testsuchmaschine mit Probanden aus der Medizin durchgeführt. Die Testpersonen attestierten dem Such-interface eine hohe Gebrauchstauglichkeit und Nützlichkeit. Der szenariobasierte Usability-Test hat zudem gezeigt, dass die Testpersonen bzw. User die integrierten Unterstützungs-maßnahmen zur Erhöhung der Benutzerfreundlichkeit während der Suche als sehr positiv und nützlich bewerten. In der Testsuchmaschine wurde diese Unterstützung z. B. durch das Aufklappen und Präsentieren von verwandten MeSH- und ICD-10-Begriffen realisiert. Die Einführung eines Schiebereglers zur effektiven Eingrenzung des Suchraums wurde ebenfalls überwiegend positiv bewertet. Zudem wurden nach Abschicken der Suchanfrage sogenannte Verwandte Suchbegriffe aus verschiedenen medizinischen Teilbereichen angezeigt. Diese Facetten-Funktion diente der Eingrenzung bzw. Verfeinerung der Suche und wurde von den Testpersonen mehrheitlich als ein sinnvolles Hilfsangebot bewertet. Insgesamt stellt das MorphoSaurus-Projekt - mit seinem spezifischen Ansatz - ein gelungenes Beispiel für die Innovationsfähigkeit von Bibliotheken im Bereich der öffentlichen Informationsversorgung dar. Durch die mögliche Anpassung der MorphoSaurus-Technologie mittels fachspezifischer Thesauri ist zudem eine hohe Anschlussfähigkeit für Suchmaschinen-projekte anderer Inhaltsdomänen gegeben.
