Abstract

Es wird ein einführender Überblick über das seit Frühjahr 2002 allgemein verfügbare Ontologiesystem OpenCyc und seine gegenwärtige Wissensbasis gegeben. Das System ist Prototyp eines logikbasierten Wissensrepräsentationssystems und der lnhalt der fortschreib-baren Wissensbasis ist eine universelle Dachontologie, die als ein Extrakt aus langjähriger Erfahrung mit ihrer Anwendung angesehen werden kann. Die Wissensrepräsentationssprache CycL von OpenCyc konkurriert mit der bisher weniger ausdrucksstarken Sprache OWL, die von den W3C-Gremien für das "Semantic Web"standardisiert wird.

Content

Wer über Ontologien und Ontologiesysteme spricht, sollte auch das System OpenCyc kennen. Aber was heißt hier "kennen"? Ich habe mich als Leser und experimentierender Benutzer mit diesem System intensiver befasst und unter einer Reihe von spezielleren Fragen an das System meine Erfahrungen in einigen Arbeitspapieren protokolliert. Sie sind über das Internet zugänglich'. Hier möchte ich der allgemeinen Orientierung über OpenCyc dienende Anmerkungen dazugeben. Bereits eine Recherche mit der Suchmaschine Google, den Suchworten "Cyc OpenCyc" und Beschränkung der Quellen auf Sprache Deutsch oder Herkunft Deutschland erbringt einige der auch hier wiedergegebenen vordergründigen Informationen, sie zeigt aber auch, dass sich Professoren oder Studenten im Jahr 2003 z.B. in Ulm, Heidelberg, Berlin, Bamberg, Bonn und Darmstadt mit dem Thema Cyc und OpenCyc beschäftigt haben entsprechend meiner Titelthese.
Das Projekt Cyc ist im Jahre 1984 angetreten mit der Zielsetzung, im großen Maßstab Alltags- und enzyklopädisches Wissen in einem einheitlichen System zu formalisieren im Gegensatz zu den bisherigen Versuchen der jeweiligen Repräsentation sektoralen Expertenwissens. Nachdem man sich dem Mythos Cyc zunächst nur über Publikationen nähern konntet, wurde dann 1997 als Textdatei Cycs "Upper Ontology" durch die Firma Cycorp Inc. zugänglich gemacht. Sie enthielt aber einiges nicht, was beschrieben worden war: z.B. Regeln und die Bindung von Aussagen an "Mikrotheorien". Entsprechend dieser Beschränkung war es mir möglich, den Inhalt dieser Datei strukturell verlustfrei in mein objektorientiertes, generisches Thesaurussystem "TerminologyFramework" einzubringen. Im April 200z wurden dann unter dem Namen OpenCyc nicht nur der Inhalt eines Auszugs aus Cycorps Ontologie, sondern auch zugehörige Werkzeuge zum lesenden Stöbern, Ändern und Schließen in einem ersten Release 0.6 zugänglich. Dazu findet man reichlich tutorielles Material, jedoch ist es nicht exakt abgestimmt auf die aktuell vorliegende Wissensbasis, sowie allerhand Dokumentation; vor allem aber findet man zum Herunterladen das Softwarepaket samt Wissensbasis für Windows NT/2000/XP- oder für Linux-Systeme. In welchem Verhältnis das nun kostenlos mit einer "GNU Lesser General Public License" verfügbare OpenCyc zu dem kommerziellen "Full Cyc" der Firma Cycorp steht, darüber weiß ich nichts aus erster Hand; die von mir für OpenCyc ermittelten Zahlen (s.u.) stehen zu neueren Angaben für Cyc in einem Größenordnungsverhältnis von ca. 1 zu 10. Informationen über realisierte Anwendungen kann man der Firmenselbstdarstellung$ und den von dort erreichbaren "white papers" entnehmen. Auf der Firmeneingangsseite findet man in Gestalt einer Pyramide eine Inhaltsübersicht der Ontologie von Cyc (siehe Abbildung 1): Beim Darüberfahren mit der Maus wird das dort wie auch hier kaum leserliche Kleingedruckte im Feld links oben lesbar und durch Klicken wird eine Inhaltsbeschreibung des jeweiligen Begriffsbereichs im Feld unten gegeben. OpenCyc stellt wohl einen exemplarischen Auszug aus dem oberen Teil der Pyramide oberhalb "Domain-Specific Knowledge" dar.
