- Abstract
- Ziel: Ziel dieser Bachelorarbeit war es, die Übertragbarkeit der allgemeinen Rankingfaktoren, wie sie von Web-Suchmaschinen verwendet werden, auf Discovery-Systeme zu analysieren. Dadurch könnte das bisher hauptsächlich auf dem textuellen Abgleich zwischen Suchanfrage und Dokumenten basierende bibliothekarische Ranking verbessert werden. Methode: Hierfür wurden Faktoren aus den Gruppen Popularität, Aktualität, Lokalität, Technische Faktoren, sowie dem personalisierten Ranking diskutiert. Die entsprechenden Rankingfaktoren wurden nach ihrer Vorkommenshäufigkeit in der analysierten Literatur und der daraus abgeleiteten Wichtigkeit, ausgewählt. Ergebnis: Von den 23 untersuchten Rankingfaktoren sind 14 (61 %) direkt vom Ranking der Web-Suchmaschinen auf das Ranking der Discovery-Systeme übertragbar. Zu diesen zählen unter anderem das Klickverhalten, das Erstellungsdatum, der Nutzerstandort, sowie die Sprache. Sechs (26%) der untersuchten Faktoren sind dagegen nicht übertragbar (z.B. Aktualisierungsfrequenz und Ladegeschwindigkeit). Die Linktopologie, die Nutzungshäufigkeit, sowie die Aktualisierungsfrequenz sind mit entsprechenden Modifikationen übertragbar.

- Abstract
- An Internet survey of 38 different OPAC systems, at eighty different libraries, was undertaken to investigate the effect on retrieval of the presence of the hyphen or the ampersand in titles. Title and Keyword searches were performed. In Title search, 22 of the systems treat the hyphen as equivalent to a space, while in Keyword the number is 16. The other systems treat it in various different ways (even including the equivalent of NOT), which means that results of searching multiple catalogs are very inconsistent. The ampersand may be ignored, treated as a special character, or treated as "and," again with very inconsistent results. Various recommendations are made with a view to improving consistency of performance.

- Abstract
- Die Überführung der konventionellen Zettelkataloge in weltweit frei zugängliche Online-Kataloge zählt zu den größten Errungenschaften der Bibliotheksautomatisierung. Seit den ersten Implementierungen in den siebziger Jahren des letzten Jahrhunderts wurden die Programmfunktionen der "elektronischen Zettelkästen" stetig ausgebaut. Heutige Kataloge bilden den Kern integrierter Bibliothekssysteme, die sowohl die innerbetrieblichen als auch die geschäftsübergreifenden Prozesse unterstützen - angefangen von der Erwerbung über die Katalogisierung bis hin zur Ausleihe von Medien. Die Entwicklung der Bibliothekssysteme orientierte sich lange Zeit ausschließlich an bibliothekarischen Anforderungen. Die Bedürfnisse der Nutzer fanden kaum Berücksichtigung oder wurden in einigen Bereichen gänzlich außer Acht gelassen. Es ist daher nicht verwunderlich, dass ein Großteil der heutigen Benutzer Internet-Suchmaschinen als Einstieg für ihre Literaturrecherche verwendet. Internet-Suchmaschinen haben in den letzten zehn Jahren den Prozess der Informationsrecherche revolutioniert. Bekanntestes Beispiel ist der Weltmarktführer Google, der in Deutschland knapp 90 Prozent der an Suchmaschinen gerichteten Anfragen beantwortet. Der große Erfolg von Google gründet sich im Wesentlichen auf vier Faktoren: leichte Bedienbarkeit, Schnelligkeit der Suche, Größe des Indexvolumens und relevanzbezogene Ranking-Algorithmen. Insbesondere die von Internet-Suchmaschinen standardmäßig vorgenommene Sortierung der Treffer nach Relevanz hat das Suchverhalten der Nutzer nachhaltig beeinflusst. So zeigen verschiedene Studien, dass die Benutzer in der Regel nur zwei bis drei Begriffe in das einzeilige Suchformular eingeben und sich dann anschließend auf die Treffer beschränken, die ohne Scrollen zu erreichen sind. Durchschnittlich werden daher pro Recherche lediglich fünf Treffer angeklickt und gesichtet. Der gesamte Vorgang dauert nur etwa 15 Sekunden. Wird das Gesuchte in dieser Zeit nicht gefunden, wird die Suche abgebrochen oder modifiziert. Das bei den Suchmaschinen zur Gewohnheit gewordene Suchverhalten wird von den Nutzern zunehmend auch auf andere Recherchesysteme übertragen. Bibliotheken und Softwarehersteller von Bibliothekssystemen haben diesen Trend erkannt und in den letzten Jahren verstärkt damit begonnen, ihre Suchsysteme an die geänderten Nutzungsgewohnheiten der Endanwender anzupassen.

- Rez. in Mitt VÖB 64(2011) H.1, S.151-153 (S. Breitling): "Wie sieht die Rolle der Katalogisierung im 21. Jahrhundert aus? In diversen Blogs und Mailinglisten wird darüber seit geraumer Zeit diskutiert. Der Bereich Katalogisierung befindet sich in einer Phase tiefgreifenden Wandels, ausgelöst durch eine Vielzahl von Faktoren, von denen veränderte Nutzererwartungen bei der Recherche und die wachsende Menge an neuen zu katalogisierenden Materialien (e-Books, Web-Ressourcen etc.) und Formaten nur zwei Aspekte darstellen. Das technische Umfeld wird nicht zuletzt durch fortgeschrittene Möglichkeiten im Bereich Retrieval und Präsentation geprägt. Wie schafft man es, dass Katalogisierung als Teil des gesamten Bibliothekswesens relevant und zeitgemäß bleibt? Welche der in Jahrzehnten Katalogisierungspraxis erarbeiteten Standards sind erhaltenswert, und welche sind im Hinblick auf den Fortschritt der IT und ein mögliches Semantic Web vielleicht gar nicht mehr nötig oder müssen an die Gegebenheiten angepasst werden? Mit diesen und anderen Fragen beschäftigt sich die Aufsatzsammlung "Conversations with catalogers in the 21st century". In der Community bekannte Personen wie Martha Yee, Christine Schwartz oder James Weinheimer kommen zu Wort, aus dem deutschsprachigen Raum Bernhard Eversberg, Entwickler des Bibliothekssystems Allegro.
