This paper shows how a question-answering system can be constructed usingfirst-order logic as its language and a resolution-type theorem-prover as itsdeductive mechanism. A working computer-program, Q A3, based on theseideas is described. The performance of the program compares favorably withseveral other general question-answering systems.Reprinted in B. L.
