- Abstract
- Elektronische Bibliothekskataloge und Bibliografien haben ihr Monopol bei der Suche nach Büchern, Aufsätzen, musikalischen Werken u. a. verloren. Globale Suchmaschinen sind starke Konkurrenten, und Bibliotheken müssen heute so planen, dass ihre Dienstleistungen auch morgen noch interessant sind. Die Deutsche Bibliothek (DDB) wird ihre traditionelle Katalogrecherche zu einem globalen, netzbasierten Informationssystem erweitern, das die Vorteile der neutralen, qualitätsbasierten Katalogsuche mit den Vorteilen moderner Suchmaschinen zu verbinden sucht. Dieser Beitrag beschäftigt sich mit der Verbesserung der inhaltlichen Suchmöglichkeiten im Informationssystem Der Deutschen Bibliothek. Weitere Entwicklungsstränge sollen nur kurz im Ausblick angerissen werden.

- Abstract
- Das Internet wird immer unübersichtlicher - auch eine Binsenweisheit, aber wohl mehr ein handfestes Problem. Abhilfe versprechen die diversen Suchmaschinen und Verzeichnisse der kommerziellen Anbieter, zu denen sich thematische Link-Sammlungen anderer Institutionen - etwas Bibliotheken - gesellen. Während die Suchmaschinen mit dem Anspruch arbeiten, das gesamte Netz zu erschließen (und diesen damit einlösen, daß sie ihre Kundschaft teilweise mit mehreren hundert Treffern nach einer Anfrage konfrontieren), haben die Anbieter ausgewählter und intellektuelle erschlossener Quellen häufig mit dem Problem mangelnder Aktualität und der Beschränktheit ihres Angebots zu kämpfen. - Der folgende Beitrag diskutiert verschiedene Verfahren, die in erheblich stärkerem Maße sowohl die Vollständigkeit als auch die Relevanz der durchsuchten beziehungsweise gefundenen Internetquellen sicherstellen sollen. In diesem Zusammenhang wird auch die Frage erörtert, welche Rolle den Bibliotheken bei der Entwicklung und Anwendung solcher Techniken zukommen könnte

- Abstract
- Das Verfahren zur automatischen syntaktischen inhaltlichen Erschließung von elektronischen Texten, AspectiX, basiert auf einem Index, dessen Elemente mit einer universellen Aspekt-Klassifikation verknüpft sind, die es erlauben, ein syntaktisches Retrieval durchzuführen. Mit diesen, auf den jeweiligen Suchgegenstand inhaltlich bezogenen Klassifikationselementen, werden die Informationen in elektronischen Texten mit bekannten Suchalgorithmen abgefragt und die Ergebnisse entsprechend der Aspektverknüpfung ausgewertet. Mit diesen Aspekten ist es möglich, unbekannte Textdokumente automatisch fachgebiets- und sprachunabhängig nach Inhalten zu klassifizieren und beim Suchen in einem Textcorpus nicht nur auf die Verwendung von Zeichenfolgen angewiesen zu sein wie bei Suchmaschinen im WWW. Der Index kann bei diesen Vorgängen intellektuell und automatisch weiter ausgebaut werden und liefert Ergebnisse im Retrieval von nahezu 100 Prozent Precision, bei gleichzeitig nahezu 100 Prozent Recall. Damit ist das Verfahren AspectiX allen anderen Recherchetools um bis zu 40 Prozent an Precision bzw. Recall überlegen, wie an zahlreichen Recherchen in drei Datenbanken, die unterschiedlich groß und thematisch unähnlich sind, nachgewiesen wird

- Abstract
- Spätestens seit dem Deutschen Bibliothekartag 2018 hat sich die Diskussion zu den automatischen Verfahren der Inhaltserschließung der Deutschen Nationalbibliothek von einer politisch geführten Diskussion in eine Qualitätsdiskussion verwandelt. Der folgende Beitrag beschäftigt sich mit Fragen der Qualität von Inhaltserschließung in digitalen Zeiten, wo heterogene Erzeugnisse unterschiedlicher Verfahren aufeinandertreffen und versucht, wichtige Anforderungen an Qualität zu definieren. Dieser Tagungsbeitrag fasst die vom Autor als Impulse vorgetragenen Ideen beim Workshop der FAG "Erschließung und Informationsvermittlung" des GBV am 29. August 2018 in Kiel zusammen. Der Workshop fand im Rahmen der 22. Verbundkonferenz des GBV statt.
