- 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
- Wenn man ein Computerprogramm besitzt, das einem zu fast jedem Textwort dessen grammatische Merkmale bestimmt und außerdem noch seine interne Struktur und einige semantische Informationen liefert, dann fragt man sich irgendwann: Könnte ich nicht auf der Grundlage dieser Angaben einen Text global charakterisieren, etwa indem ich versuche, die wichtigen Wörter dieses Textes zu errechnen? Die häufigsten Textwörter können es nicht sein, denn gerade sie sind sehr nichtssagend. Die seltensten Textwörter sind zwar aussagekräftig, aber sie sind zu viele - die meisten Lemmata eines Textes erscheinen nur ein einziges Mal. Irgendwie müsste man den Wortschatz einschränken können. Die rettende Idee war: Wir tun so, als seien die semantischen Merkmale Wörter, denn dann enthält der Wortschatz dieser Sprache nur noch etwa hundert Elemente, weil unsere morphologische Analyse (Mpro) rund 100 semantische Features verwendet. Wir vermuteten nun, dass die häufig vorkommenden Features wichtig für den Text sind und die selteneren als Ausreißer betrachten werden können. Die Implementierung dieser Idee ist der Urahn unseres Programmpaketes AUTINDEX zur automatischen Indexierung von Texten. Dieses allererste Programm erstellte also zu einem Text eine Statistik der semantischen Merkmale und gab die drei häufigsten Klassen mit den zugehörigen Lemmata aus. Das Ergebnis war verblüffend: Auf den ersten Blick konnte man sehen, worum es in dem Text ging. Bei näherem Hinsehen wurden aber auch Unzulänglichkeiten deutlich. Einige der Schlagwörter waren doch ziemlich nichtssagend, andere hätte man gerne in der Liste gehabt, und schließlich hätte man sich noch eine ganz globale Charakterisierung des Textes durch die Angabe von Fachgebieten gewünscht, etwa in der Form: Der Text hat mit Politik oder Wirtschaft zu tun, er berichtet über einen Unfall, eine Feierlichkeit usw. Es wurde also sofort deutlich, dass das Programm ohne eine weitere Wissensquelle keine wirklich guten Ergebnisse würde liefern können. Man braucht also einen Thesaurus, ein Wörterbuch, in dem einzelne Lemmata und auch mehrwortige Ausdrücke mit zusätzlichen Informationen versehen sind.
