- Abstract
- Vor rund 25 Jahren entwarf Umberto Eco anlässlich des Jubiläums einer italienischen Stadtbibliothek die negative Utopie einer benützerfeindlichen Bibliothek, an deren hervorstechendste Eigenschaften im vorliegenden Beitrag erinnert wird. Vieles damals teils als Desiderat, teils fast als Utopie Empfundene ist heute erreicht, ja Selbstverständlichkeit geworden. Überträgt man Ecos Betrachtungsweise auf einige Aspekte der Benützerfreundlichkeit heutiger digitaler Bibliotheken und Informationsressourcen, wie z. B. Navigierbarkeit und Zugänglichkeit, lassen sich auch hier noch, dem Erreichten zum Trotz, Desiderate und Raumfür Utopien aufzeigen.

- Abstract
- In folgendem Beitrag werden die Möglichkeiten von semantischen Technologien im Einsatz innerhalb konkreter Anwendungen aufgezeigt. Die Einsatzbereiche umfassen semantische Suchsysteme, die das Auffinden von Dokumenten und Datenbank-Informationen unterstützen, Lösungen zur semantischen Integration von verteilten Datenquellen bis hin zu semantischen Ratgeberlösungen. Anhand zweier Praxisbeispiele werden die eingesetzten Technologien illustriert. Das erste Beispiel zeigt den Einsatz eines ontologiebasierten Systems zur Suche und Integration von Dokumenten und Daten in einem großen deutschen Telekommunikationsunternehmen. Dabei werden verschiedene Quellen - z. B. ein DMS System und ein Intranet - integriert und in diesen mit Hilfe von Ontologien übergreifend nach Inhalten gesucht. Das zweite Industrieprojekt zeigt den Einsatz eines semantischen Ratgebersystems zur Unterstützung des Kundenservice bei einem Roboterhersteller. Hierbei wird neben dem verwendeten Problemlösungsverfahren auch die Integration von strukturierten Quellen aufgezeigt. Semantische Technologien haben die Forschungslabors verlassen und werden nutzenstiftend in Industrieprojekten eingesetzt. Diese zentrale Aussage des Beitrages wird durch vertiefte Erläuterungen der eingesetzten Methoden und Darstellungen der verwendeten Werkzeuge erweitert.

- Abstract
- Das Klassifizieren von Objekten (z. B. Fauna, Flora, Texte) ist ein Verfahren, das auf menschlicher Intelligenz basiert. In der Informatik - insbesondere im Gebiet der Künstlichen Intelligenz (KI) - wird u. a. untersucht, inweit Verfahren, die menschliche Intelligenz benötigen, automatisiert werden können. Hierbei hat sich herausgestellt, dass die Lösung von Alltagsproblemen eine größere Herausforderung darstellt, als die Lösung von Spezialproblemen, wie z. B. das Erstellen eines Schachcomputers. So ist "Rybka" der seit Juni 2007 amtierende Computerschach-Weltmeistern. Inwieweit Alltagsprobleme mit Methoden der Künstlichen Intelligenz gelöst werden können, ist eine - für den allgemeinen Fall - noch offene Frage. Beim Lösen von Alltagsproblemen spielt die Verarbeitung der natürlichen Sprache, wie z. B. das Verstehen, eine wesentliche Rolle. Den "gesunden Menschenverstand" als Maschine (in der Cyc-Wissensbasis in Form von Fakten und Regeln) zu realisieren, ist Lenat's Ziel seit 1984. Bezüglich des KI-Paradeprojektes "Cyc" gibt es CycOptimisten und Cyc-Pessimisten. Das Verstehen der natürlichen Sprache (z. B. Werktitel, Zusammenfassung, Vorwort, Inhalt) ist auch beim intellektuellen Klassifizieren von bibliografischen Titeldatensätzen oder Netzpublikationen notwendig, um diese Textobjekte korrekt klassifizieren zu können. Seit dem Jahr 2007 werden von der Deutschen Nationalbibliothek nahezu alle Veröffentlichungen mit der Dewey Dezimalklassifikation (DDC) intellektuell klassifiziert.
Die Menge der zu klassifizierenden Veröffentlichungen steigt spätestens seit der Existenz des World Wide Web schneller an, als sie intellektuell sachlich erschlossen werden kann. Daher werden Verfahren gesucht, um die Klassifizierung von Textobjekten zu automatisieren oder die intellektuelle Klassifizierung zumindest zu unterstützen. Seit 1968 gibt es Verfahren zur automatischen Dokumentenklassifizierung (Information Retrieval, kurz: IR) und seit 1992 zur automatischen Textklassifizierung (ATC: Automated Text Categorization). Seit immer mehr digitale Objekte im World Wide Web zur Verfügung stehen, haben Arbeiten zur automatischen Textklassifizierung seit ca. 1998 verstärkt zugenommen. Dazu gehören seit 1996 auch Arbeiten zur automatischen DDC-Klassifizierung bzw. RVK-Klassifizierung von bibliografischen Titeldatensätzen und Volltextdokumenten. Bei den Entwicklungen handelt es sich unseres Wissens bislang um experimentelle und keine im ständigen Betrieb befindlichen Systeme. Auch das VZG-Projekt Colibri/DDC ist seit 2006 u. a. mit der automatischen DDC-Klassifizierung befasst. Die diesbezüglichen Untersuchungen und Entwicklungen dienen zur Beantwortung der Forschungsfrage: "Ist es möglich, eine inhaltlich stimmige DDC-Titelklassifikation aller GVK-PLUS-Titeldatensätze automatisch zu erzielen?"

- Abstract
- In this paper, we discuss Conceptual Knowledge Discovery in Databases (CKDD) in its connection with Data Analysis. Our approach is based on Formal Concept Analysis, a mathematical theory which has been developed and proven useful during the last 20 years. Formal Concept Analysis has led to a theory of conceptual information systems which has been applied by using the management system TOSCANA in a wide range of domains. In this paper, we use such an application in database marketing to demonstrate how methods and procedures of CKDD can be applied in Data Analysis. In particular, we show the interplay and integration of data mining and data analysis techniques based on Formal Concept Analysis. The main concern of this paper is to explain how the transition from data to knowledge can be supported by a TOSCANA system. To clarify the transition steps we discuss their correspondence to the five levels of knowledge representation established by R. Brachman and to the steps of empirically grounded theory building proposed by A. Strauss and J. Corbin
