The motivation for this adjunct test came from an exploratory s tudy done by Beth Sundheim during MUC-3. This s tudy showed a degradation in correctness of message processing as the information distribution in the message became more complex, that is, as slot fills were drawn from larger portions of the message and required more discourse processing to extract the information and reassemble it ...
