Raymond Reiter: On Closed World Data Bases. In: H. Gallaire et al. (Hrsg.): Logic and Data Bases. Plenum Press, New York 1978, ISBN 1-4684-3386-5, S.55–76, doi:10.1007/978-1-4684-3384-5_3 (englisch): “The open world assumption corresponds to the usual first order approach to query evaluation: Given a data base DB and a query Q, the only answers to Q are those which obtain from proofs of Q given DB as hypotheses. Under the closed world assumption, certain answers are admitted as a result of failure to find a proof. More specifically, if no proof of a positive ground literal exists, then the negation of that literal is assumed true.”
