- Abstract
- Manuelles Blättern im Zettelkasten hat vielfach ausgedient. Konventionelle Dokumentationsmethodem werden mehr und mehr dutch modernen Methoden des Information Retrieval (IR) ersetzt. Doch auch im Umgang mit Datenbanken sind Benutzer kritischer geworden. Sie fragen immer öfter, wieviel der gewünschten Information nicht gefunden wurde, obwohl sie im Informationssystem gespeichert ist

- Abstract
- Der "Digitale Assistent" DA-3 ist ein webbasiertes Tool zur maschinellen Unterstützung der intellektuellen verbalen und klassifikatorischen Inhaltserschließung. Im Frühjahr 2016 wurde einer breiteren Fachöffentlichkeit die zunächst für den Einsatz im IBS|BW-Konsortium konzipierte Vorgängerversion DA-2 vorgestellt. Die Community nahm die Entwicklung vor dem Hintergrund der strategischen Diskussionen um zukunftsfähige Verfahren der Inhaltserschließung mit großem Interesse auf. Inzwischen wird das Tool in einem auf drei Jahre angelegten Kooperationsprojekt zwischen der Firma Eurospider Information Technology, dem IBS|BW-Konsortium, der Staatsbibliothek zu Berlin und den beiden Verbundzentralen VZG und BSZ zu einem zentralen und leistungsstarken Service weiterentwickelt. Die ersten Anwenderbibliotheken in SWB und GBV setzen den DA-3 während dieser Projektphase bereits erfolgreich ein, am Ende ist die Überführung in den Routinebetrieb vorgesehen. Der Beitrag beschreibt den derzeitigen Stand und Nutzen des Projekts im Kontext der aktuellen Rahmenbedingungen, stellt ausführlich die Funktionalitäten des DA-3 vor, gibt einen kleinen Einblick hinter die Kulissen der Projektpartner und einen Ausblick auf kommende Entwicklungsschritte.

- Abstract
- Seit Juni 2013 ist der Digitale Assistent in den Workflow der Erschließungsprozesse der Zentralbibliothek Zürich integriert. Das System des Digitalen Assistenten kombiniert automatisch unterstützte Prozesse und intellektuelle Sacherschließung: Es werden Schlagwortvorschläge generiert, die danach intellektuell von den Fachreferenten überprüft werden. Im vorliegenden Beitrag wird die Entwicklung des Digitalen Assistenten im Kontext der Praxis der Sacherschließung im Allgemeinen und in der Zentralbibliothek Zürich im Speziellen skizziert. Im Anschluss werden die unterschiedlichen Prozesse der Datenverarbeitung des Systems näher erläutert, sodann wird auf Basis von Statistiken ein erstes Resümee gezogen. Ausführungen zu technischen Spezifikationen runden den Bericht ab.

- Abstract
- Der Beitrag stellt eine umfangreiche Evaluation der Suchfunktionen von 35 deutschen Unternehmenswebsites vor. In der Studie soll die vom Nutzer wahrgenommene Qualität einer Website-Suche erfasst werden, und nicht die technische Funktionalität der jeweiligen Systeme. In leitfaden-basierten Evaluationen werden die Bereiche Suchindex, Anfrage- / Dokumentenvergleich, Benutzerinteraktion und Suchergebnisse untersucht. Die Zusammenfassung der Ergebnisse der Einzeltests in diesen Kategorien ermöglicht eine qualitative Beurteilung und Aussagen über die Positionierung von Ergebnissen relativ zum Gesamtfeld. Die Ergebnisse zeigen, dass bei Internetauftritten die Suchfunktion auf Websites oft zum Problem werden kann. Die Benutzer haben häufig Anlass, die Website zu verlassen, ohne ihr Ziel erreicht zu haben. Probleme zeigten sich bei der Vollständigkeit und Aktualität des Suchindexes sowie bei der Pflege und Präsentation ergänzender .Metadaten. Zum Vergleich werden die Untersuchungen auch anhand der Google-Sitesearch durchgeführt. Dabei zeigt sich, dass eine genaue Kenntnis der eigenen Daten zu besseren Ergebnissen führen kann, dies nutzen Unternehmen aber nicht immer aus.

- Abstract
- Die Ausgangslage für Suchfunktionen auf Unternehmens-Websites stellt sich grundlegend anders dar als bei Internet-Suchdiensten. Nicht die möglichst breite Erschließung von Informationen vieler verschiedener Websites, sondern der erfolgreiche Dialog mit den Nutzern steht im Vordergrund. Das Gelingen dieser Kommunikation wird in diesem Beitrag untersucht. Von 56 Schweizer Unternehmen und Behörden wurde jeweils die Suchfunktion der Website untersucht. Dabei gruppierten sich die insgesamt 74 Einzeltests in die vier Hauptkriterien: Suchindex, Vergleich von Anfragen und Dokumenten, Benutzerinteraktion und Suchergebnisse. Die Resultate zeigen großes Potential für Verbesserungen. Dabei wurden kein Ranking der Websites und keine Auszeichnung im Rahmen der Studie beabsichtigt. Vielmehr wurde auf Basis der Ergebnisse eine Einteilung in gute, mittlere und schlechte Websites für die einzelnen Kriterien durchgeführt. Die Analyse zeigt, dass keine Website in sämtlichen getesteten Kriterien sehr gut abschneidet. Die Studie schließt mit verschiedenen Empfehlungen, die dazu führen können, die Qualität der Suchfunktion wesentlich zu verbessern. Hierbei wird unter anderem empfohlen, der Aktualität und Vollständigkeit des Suchindex besondere Beachtung zu schenken, Metadaten der Dokumentenbasis zu pflegen, bewährte Standards für die Benutzerinteraktion zu beachten und Trefferlisten sowie potenzielle Suchanfragen auch auf eine mögliche Nutzersicht hin zu optimieren.

- Abstract
- Wir beschreiben den Digitalen Assistenten DA-2, den wir zur Unterstützung der Sacherschliessung im IBS-Verbund implementiert haben. Diese webbasierte Anwendung ist eine vollständige Neuimplementierung, welche die Erkenntnisse des Vorgängersystems bei der Zentralbibliothek Zürich berücksichtigt. Wir stellen Überlegungen zur Zukunft der Sacherschliessung an und geben eine Übersicht über Projekte mit ähnlichen Zielsetzungen, die Sacherschließung mit Computerunterstützung effizienter und besser zu gestalten.
