Prolog stands for ‘Programming in Logic.’ It is mainly used for AI and computational linguistics.

It is a declarative language and particularly useful for symbolic reasoning, database, language parsing applications, and natural language processing. It was developed in 1972 by Alain Colmerauer and Phillippe Roussel based on Robert Kowalski’s procedural interpretation of Horn Clauses, a logical formula of a rule-like form. It is still used in academics and research as a part of artificial intelligence.

It is not used as extensively as other common languages. It was one of the popular logic programming languages at that time with its usage in expert systems, theorem proving, type systems, and automated planning.

However, Prolog’s potential was not recognized and it was rarely used in commercial applications. Prolog is still used in IBM Watson and some NLP applications.


Lisp was the first language developed for AI. It is the second oldest programming language after Fortran and is considered one of the pioneers in computer science and the implementation of AI. It was developed by John McCarthy in 1958 and there are many dialects available today over the years.

The best-known and popular dialects are Racket, Scheme, Clojure, and Common Lisp.

It is one of the earliest programming languages and quickly became popular in the field of AI.

Lisp offers several features that include rapid prototyping, garbage collection, dynamic object creation, flexibility, information process capability, and so on. It was originally built as a practical mathematical notation for computer programs. This idea makes it more suitable for artificial intelligence and machine learning.
