Prolog \Pro"log\, n. & v. Prologue. [1913 Webster]
The Collaborative International Dictionary of English v.0.48:

PROLOG \PRO"LOG\ (pr[=o]"l[o^]g), n. (Computers) A declarative higher-level programming language in which instructions are written not as explicit procedural data-manipulation commands, but as logical statements. The language has built-in resolution procedures for logical inference. [PJC]
The Collaborative International Dictionary of English v.0.48:

higher programming language \higher programming language\ n. (Computers) A computer programming language with an instruction set allowing one instruction to code for several assembly language instructions. Note: The aggregation of several assembly-language instructions into one instruction allows much greater efficiency in writing computer programs. Most programs are now written in some higher programming language, such as BASIC, FORTRAN, COBOL, C, C++, PROLOG, or JAVA. [PJC]

The Free On-line Dictionary of Computing (18 March 2015):

Prolog Programming in Logic or (French) Programmation en Logique. The first of the huge family of logic programming languages. Prolog was invented by Alain Colmerauer and Phillipe Roussel at the University of Aix-Marseille in 1971. It was first implemented 1972 in ALGOL-W. It was designed originally for natural-language processing but has become one of the most widely used languages for artificial intelligence. It is based on LUSH (or SLD) resolution theorem proving and unification. The first versions had no user-defined functions and no control structure other than the built-in depth-first search with backtracking. Early collaboration between Marseille and Robert Kowalski at University of Edinburgh continued until about 1975. Early implementations included C-Prolog, ESLPDPRO, Frolic, LM-Prolog, Open Prolog, SB-Prolog, UPMAIL Tricia Prolog. In 1998, the most common Prologs in use are Quintus Prolog, SICSTUS Prolog, LPA Prolog, SWI Prolog, AMZI Prolog, SNI Prolog. ISO draft standard at Darmstadt, Germany (ftp://ftp.th-darmstadt.de/pub/programming/languages/prolog/standard/). or UGA, USA (ftp://ai.uga.edu/ai.prolog.standard). See also negation by failure, Kamin's interpreters, Paradigms of AI Programming, Aditi. A Prolog interpreter in Scheme. (ftp://cpsc.ucalgary.ca/pub/prolog1.1). A Prolog package (ftp://cpsc.ucalgary.ca/pub/prolog1.1/prolog11.tar.Z) from the University of Calgary features delayed goals and interval arithmetic. It requires Scheme with continuations.
