The DLV (DataLog with Disjunction, where the * logical disjunction symbol V is used) system is a * disjunctive logic programming system, implementing the * stable model semantics under the Answer set programming * paradigm. It extends the datalog language to allow the * use of OR in rules. * Briefly, disjunctive Datalog is a variant of Datalog where disjunctions * may appear in the rule heads; advanced versions also allow for negation * in the bodies, which can be handled according to a semantics for negation * in disjunctive logic programming. * A disjunctive Datalog rule is a clause of the form:* * * * * a * * 1 * * * ∨ * ⋯ * ∨ * * a * * n * * * ← * * b * * 1 * * * ∧ * ⋯ * ∧ * * b * * m * * * * 1 * ≤ * n * , * 0 * ≤ * m * * * {\displaystyle a_{1}\vee \dots \vee a_{n}\leftarrow b_{1}\wedge \dots \wedge b_{m}\quad 1\leq n,0\leq m} * * A disjunctive Datalog constraint is a clause of the form: * * * * * ← * * b * * 1 * * * ∧ * ⋯ * ∧ * * b * * m * * * * 0 * ≤ * m * * * {\displaystyle \leftarrow b_{1}\wedge \dots \wedge b_{m}\quad 0\leq m} * * One of the most popular nonmonotonic logics is Reiter’s [1980] default * logic. This logic was developed as a knowledge representation formalism * and was originally not conceived as a database query language. However, * a suitable setting was defined in which default logic can be used as a * query language for relational databases (Default Query Language, DQL). * From a practical point of view, in the context of deductive databases * disjunctive Datalog seems to be the more suitable extension of DATALOG~ * than DQL. Due to its plain syntax, DATALOGv,~ is amenable to automatic * program analysis and optimization. * These results are not only of theoretical interest; problems relevant in * practice such as computing the optimal tour value in the Traveling Salesman * Problem and eigenvector computations can be handled in disjunctive Datalog, but * not Datalog with negation (unless the Polynomial Hierarchy collapses) . * Example Input: Datalog with Negation as Failure * * smoker(john). * smoker(jack). * * jogger(jill). * jogger(john). * * healthy(X) :- jogger(X), \+ smoker(X). * * Translation to DLV: Take Clark Completion and Clausal Form * * smoker(X) <- X=john. * smoker(X) <- X=jack. * X=john v X=jack <- smoker(X). * * jogger(X) <- X=jill. * jogger(X) <- X=john. * X=jill v X=john <- jogger(X). * * healthy(X) v smoker(X) <- jogger(X). * jogger(X) <- healthy(X) * <- healthy(X) & smoker(X). * * Example Run: Single Stable Model * * ?- healthy(X). * X = jill ; * No |
