 of
     assertions.

JA:  Here's a chance for me to ask some of my favorite questions again:

     1.  a.  What forms of reasoning are involved in the decision of
             a DBA [or a KBA] to create, modify, remove a concept
             [in/of/from] the conceptual base?

         b.  Can these putative forms of reasoning
             be computationally formalized?

DW:  I'm not John, but if I as a DBA might answer:

DW:  I don't create, modify, or remove a concept [in/of/from] a conceptual
base.
