15:45:02 <alanr> disjointWith: Classes may be stated to be disjoint from each other. For example, Man and Woman can be stated to be disjoint classes. From this disjointWith statement, a reasoner can deduce an inconsistency when an individual is stated to be an instance of both and similarly a reasoner can deduce that if A is an instance of Man, then A is not an instance of Woman.

Scribe problem: the name 'disjointWith' does not match any of the 48 active names. Either change the name used, or request the list of names be altered.Active names: Achille Fokoue Alan Ruttenberg Anne Cregan Bernardo Cuenca Grau Bijan Parsia Boris Motik Conrad Bock Deborah McGuinness Doug Lenat Elisa Kendall Enrico Franconi Evan Wallace Evren Sirin Fabian Neuhaus Fabien Gandon Giorgos Stamou Giorgos Stoilos Ian Horrocks Ivan Herman James Hendler Jeff Pan Jeremy Carroll Joanne Luciano Jonathan Rees Markus Krötzsch Martin Dzbor Michael Sintek Michael Smith Michael Schneider Olivier Corby Pascal Hitzler Peter Haase Peter Patel-Schneider Ratnesh Sahay Rinke Hoekstra Sandro Hawke Steve Battle Suzette Stoutenburg Tommie Meyer Uli Sattler Vassilis Tzouvaras Vipul Kashyap Vit Novacek Vojtech Svatek Zhe Wu Zakim IRC Bot Trackbot IRC Bot RRSAgent IRC Bot
