Abstract

Die Süddeutsche Zeitung (SZ) verfügt seit ihrer Gründung 1945 über ein Pressearchiv, das die Texte der eigenen Redakteure und zahlreicher nationaler und internationaler Publikationen dokumentiert und für Recherchezwecke bereitstellt. Die DIZ-Pressedatenbank (www.medienport.de) ermöglicht die browserbasierte Recherche für Redakteure und externe Kunden im Intra- und Internet und die kundenspezifischen Content Feeds für Verlage, Rundfunkanstalten und Portale. Die DIZ-Pressedatenbank enthält z. Zt. 7,8 Millionen Artikel, die jeweils als HTML oder PDF abrufbar sind. Täglich kommen ca. 3.500 Artikel hinzu, von denen ca. 1.000 durch Dokumentare inhaltlich erschlossen werden. Die Informationserschließung erfolgt im DIZ nicht durch die Vergabe von Schlagwörtern am Dokument, sondern durch die Verlinkung der Artikel mit "virtuellen Mappen", den Dossiers. Insgesamt enthält die DIZ-Pressedatenbank ca. 90.000 Dossiers, die untereinander zum "DIZ-Wissensnetz" verlinkt sind. DIZ definiert das Wissensnetz als Alleinstellungsmerkmal und wendet beträchtliche personelle Ressourcen für die Aktualisierung und Qualitätssicherung der Dossiers auf. Im Zuge der Medienkrise mussten sich DIZ der Herausforderung stellen, bei sinkenden Lektoratskapazitäten die Qualität der Informationserschließung im Input zu erhalten. Auf der Outputseite gilt es, eine anspruchsvolle Zielgruppe - u.a. die Redakteure der Süddeutschen Zeitung - passgenau und zeitnah mit den Informationen zu versorgen, die sie für ihre tägliche Arbeit benötigt. Bezogen auf die Ausgangssituation in der Dokumentation der Süddeutschen Zeitung identifizierte DIZ drei Ansatzpunkte, wie die Aufwände auf der Inputseite (Lektorat) zu optimieren sind und gleichzeitig auf der Outputseite (Recherche) das Wissensnetz besser zu vermarkten ist: - (Teil-)Automatische Klassifizierung von Pressetexten (Vorschlagwesen) - Visualisierung des Wissensnetzes - Neue Retrievalmöglichkeiten (Ähnlichkeitssuche, Clustering) Im Bereich "Visualisierung" setzt DIZ auf den Net-Navigator von intelligent views, eine interaktive Visualisierung allgemeiner Graphen, basierend auf einem physikalischen Modell. In den Bereichen automatische Klassifizierung, Ähnlichkeitssuche und Clustering hat DIZ sich für das Produkt nextBot der Firma Brainbot entschieden.
