Zusammenfassung
Das Tracing-Konzept ist die in Expertensystemen bislang verbreitetste Form für die Organisation von Erklärungsprozessen—ein Protokoll der Ableitungsgeschichle einer systemseilig generierten Problemlösung wird zugleich als Erklärung benutzt. Dies ist schon für Ein-Benutzer-Szenarien problematisch, für Gruppen-Problemlösungsprozesse, in deren Verlauf mehrere unterschiedlich spezialisierte menschliche Akteure und technische Entschcidungsunterslützungswerkzeuge bei der Lösung komplexer Problemstellungen kooperieren, jedoch vollends unakzepiabel. Dazu muß das bislang gebräuchliche zu cinfache Erklärungskonzept um subtilere Mechanismen (wie die Ansteuerung unterschiedlicher Abstraktionsebenen und Granularitäten von Erklärungen bzw. eingegrenzten Erklärungsteilen, (Re-)Konstruktion von Erklärungen in argumentativen Erklärungsdebatten, Analyse und Auflösung von Erklärungsfehlern durch Kritisierung von Erklärungen) eines gruppenhandlungsorientierten Argumentationsmodells erweitert werden. Seine grundlegenden Elemente werden in diesem Beitrag skizziert und am Beispiel eines Interaktionsfragments im Konlext des Gruppen-Informalionssyslems CoNeX vorgestellt.
Die hier beschriebenen Forschungsarbeitcn werden im Rahmen des DFG-Schwerpunktbcrcichs “Objektbanken für Experten“ von der Deulschen Forschungsgemeinschafi (DFG) unter der Fürdernummer Ja 445/1-1 gefördert und wurden im wesentlichen an der Universität Passau ausgeführt.
Ich möchte mich für die Implementation des Konferenzsystcms bei Rainer Gallersdörfer besonders herzlich bedanken. Matthias Jarke hat mir das Themengcbict crschlossen und durch seine Kommentare zur Entwicklung des Modells beigetragen.
