Dear all ?
The first order logic: The two first lines har fine. The third line should express that this is a short cut. 1) The class of x,y,z can be deduced from the defintion of the properties. However, in the Iraklio meeting Mark and I concluded that it is helpful for the readers to see the classes. 2) The '=' sign indicates that this is a strong shortcut. That is, the existence of an instance of the shortcut implies the existance of an instance of E92 STV. In general, we don't describe the crm shortcuts as strong. The FOL should then be Pxxy(x,y) ? E93(x), Pxxy(x,y) ? E18(y) Pxxy(x,y) ?? [E93(x) ? E18(y)? E92(z) ?? P166(x,z) ? Pxxx(y,z)] Best, Christian-Emil Pxxy was a presence of (had presence) Domain: E93 Presence Range: E18 Physical Thing Quantification: (0,1 : 0,n) Scope note: This property associates an instance of E93 Presence with an instance of E18 Physical Thing of which it represents a temporal restriction (i.e.: a time-slice). It is a shortcut of the more fully developed path from E93 Presence through P166 was a presence of E92 Spacetime Volume, Pxxxi is defined by to E18 Physical Thing. Instantiating either this property or directly Pxxx is defined by constitutes a necessary part of the identity of the respective instance of E93 Presence. In First Order Logic: Pxxy(x,y) ? E93(x), Pxxy(x,y) ? E18(y) Pxxy(x,y) = [E93(x) ? E18(y)? P166(x,z) ? Pxxx(y,z)] -- ------------------------------------ Dr. Martin Doerr Honorary Head of the Center for Cultural Informatics Information Systems Laboratory Institute of Computer Science Foundation for Research and Technology - Hellas (FORTH) N.Plastira 100, Vassilika Vouton, GR70013 Heraklion,Crete,Greece Vox:+30(2810)391625 Email: mar...@ics.forth.gr<mailto:mar...@ics.forth.gr> Web-site: http://www.ics.forth.gr/isl
