New Generation Computing 9, 401–424 (1991), Rajasekar, A., Lobo, J., Minker, J.: Weak generalized closed world assumption. << (eds.) on Foundations of Software Technology and Theoretical Computer Science, pp. It reviews the logical foundations of logic programming and derivation rule languages and describes existing Web rule standard languages such as RuleML, the W3C Rule Interchange Format (RIF), and the Web rule engine Prova. LNCS (LNAI), vol. Objectives The main objective of both editions of this textbook is to provide a uniform account of both the foundations of logic programming and simple programming techniques in the programming language Prolog. A PROLOG program consists of: Declaration of the facts of the relations involved. RIF. : Principles of Database and Knowlegebase Systems, vol. In: Stickel, M.E. Logical programming languages allow data to be represented both extensionally and intentionally. 392–407. %PDF-1.5 Fundamenta Informaticae 13, 445–463 (1990), Przymusinski, T.C. 31 0 obj MIT Press, Cambridge (1990), Gelfond, M., Lifschitz, V.: Classical negation in logic programs and disjunctive databases.

In all of these languages, rules are written in the form of clauses: 474, pp. Quantifier logic encompasses the rules of sentential logic and expands upon them so that you can write whole statements with logic symbols. : An essential hybrid reasoning system: Knowledge and symbol level accounts for krypton.

Business logic is essentially the part of a computer program that contains the information (in the form of business rules) that defines or constrains how a business operates.
