Quaker Oats Co. took over Stokely-Van Camp in 1983. we would need to write the following complex rules: is(Quaker Oats Co.,company), own(Stokely-Van Camp,Gatorade), took over (Quaker Oats Co.,Stokely-Van Camp), took over(Y, Z)→own(Z,Y), and carry out logic unification and resolution.
approaches that can automatically generate patterns (i.e., features) from syntactic and semantic representations of the Q/AP are needed.
