- Abstract
- Sachliche Suchen in bibliothekarischen Online-Katalogen enden häufig mit unbefriedigenden Ergebnissen. Als eine Ursache dafür kann angesehen werden, daß die Gestaltung des Suchprozesses das semantische Umfeld einer Suchanfrage nicht mit einbezieht, daß in Übertragung der Verhältnisse in konventionellen Katalogen am Paradigma des Wort-Matching zwischen Suchwort und Indexat festgehalten wird. Es wird statt dessen das Konzept einer semantischen Umfeldsuche entwickelt und gezeigt, welche Rolle die Verwendung strukturierten Vokabulars dafür spielen kann. Insbesondere wird dargestellt, welche Möglichkeiten Verfahren der wörterbuchgestützten maschinellen Indexierung in diesem Zusammenhang spielen können. Die Ausführungen werden durch Beispiele illustriert

- Abstract
- Since its appearance in the early 90's, the World Wide Web (WWW or Web) has provided universal access to knowledge and the world of information has been primarily witness to a great revolution (the digital revolution). It quickly became very popular, making it the largest and most comprehensive database and knowledge base thanks to the amount and diversity of data it contains. However, the considerable increase and evolution of these data raises important problems for users, in particular for accessing the documents most relevant to their search queries. In order to cope with this exponential explosion of data volume and facilitate their access by users, various models are offered by information retrieval systems (IRS) for the representation and retrieval of web documents. Traditional SRIs use simple keywords that are not semantically linked to index and retrieve these documents. This creates limitations in terms of the relevance and ease of exploration of results. To overcome these limitations, existing techniques enrich documents by integrating external keywords from different sources. However, these systems still suffer from limitations that are related to the exploitation techniques of these sources of enrichment. When the different sources are used so that they cannot be distinguished by the system, this limits the flexibility of the exploration models that can be applied to the results returned by this system. Users then feel lost to these results, and find themselves forced to filter them manually to select the relevant information. If they want to go further, they must reformulate and target their search queries even more until they reach the documents that best meet their expectations. In this way, even if the systems manage to find more relevant results, their presentation remains problematic. In order to target research to more user-specific information needs and improve the relevance and exploration of its research findings, advanced SRIs adopt different data personalization techniques that assume that current research of user is directly related to his profile and / or previous browsing / search experiences.

- Abstract
- Ausgangslage Die Katalog-Recherchen über Internet, also von außerhalb der Bibliothek, nehmen erwartungsgemäß stark zu bzw. sind mittlerweile die Regel. Damit ist natürlich das Bedürfnis und die Notwendigkeit gewachsen, über den Titel hinaus zusätzliche inhaltliche Informationen zu erhalten, die es erlauben, die Zweckmäßigkeit wesentlich besser abschätzen zu können, eine Bestellung vorzunehmen oder vielleicht auch 50 km in die Bibliothek zu fahren, um ein Buch zu entleihen. Dieses Informationsdefizit wird zunehmend als gravierender Mangel erfahren. Inhaltsverzeichnisse referieren den Inhalt kurz und prägnant. Sie sind die erste Stelle, welche zur Relevanz-Beurteilung herangezogen wird. Fast alle relevanten Terme einer Fachbuchpublikation finden sich bereits dort. Andererseits wird immer deutlicher, dass die dem bibliothekarischen Paradigma entsprechende intellektuelle Indexierung der einzelnen dokumentarischen Einheiten mit den engsten umfassenden dokumentationssprachlichen Termen (Schlagwörter, Klassen) zwar eine notwendige, aber keinesfalls hinreichende Methode darstellt, das teuer erworbene Bibliotheksgut Information für den Benutzer in seiner spezifischen Problemstellung zu aktivieren und als Informationsdienstleistung anbieten zu können. Informationen zu sehr speziellen Fragestellungen, die oft nur in kürzeren Abschnitten (Kapitel) erörtert werden, sind derzeit nur indirekt, mit großem Zeitaufwand und oft überhaupt nicht auffindbar. Sie liegen sozusagen brach. Die Tiefe der intellektuellen Indexierung bis in einzelne inhaltliche Details zu erweitern, ist aus personellen und damit auch finanziellen Gesichtspunkten nicht vertretbar. Bibliotheken fallen deshalb in der Wahrnehmung von Informationssuchenden immer mehr zurück. Die enorme Informationsvielfalt liegt hinter dem Informations- bzw. Recherchehorizont der bibliographischen Aufnahmen im Katalog.
