This is a consequence of the substitution of the antecedent ("Will Quinlan") with its NE category ("person"); such an instantiation is not frequent, since it violates standard relations within (O1).
we also instantiate (O1) by substituting N ½ with Ò , and N ¾ with the NE type of the antecedent (Á Ô ¾ in Table 3).
