    Abstract
    "Thesaurus linguae latinae" - so heißt eine der frühesten Wort-Sammlungen. Seit Alters her beschäftigen sich Menschen mit der qualifizierten Aufbereitung von Information. Noch älter ist sogar das Konzept der Ontologie (wörtlich: die "Lehre vom Sein"), die sich als Disziplin der Philosophie bereits seit Aristoteles (384-322 v. Chr.) mit einer objektivistischen Beschreibung der Wirklichkeit beschäftigt. Ontologien - als Disziplin des modernen Wissensmanagements-sind eine Methode, in möglichst kompakter Form, d.h. unter Verwendung von Konzepten in verschiedenen Meta-Ebenen die reale Welt zu beschreiben. Thesaurus und Ontologie stellen zwei Konzepte dar, die auch heute noch in der Wissenschaft - und in jüngster Zeit mit zunehmender Bedeutung auch in der Wirtschaft - im Bereich des Informationsund Wissensmanagements zum Einsatz kommen. Beide spannen gewissermaßen den konzeptionellen Bogen, an dem sich ein pragmatisches Wissensmanagement heutzutage ausrichtet und sich in Form sogenannter semantischer Netze - auch Wissensnetze genannt - wiederfindet.
