Prolog is a logic programming language that was developed in the 1970s by Alain Colmerauer and Robert Kowalski. It is based on first-order predicate logic and is used for artificial intelligence, natural language processing, and expert systems.
For example, Prolog can be used to build a chatbot that can understand and respond to user queries in a conversational manner. The chatbot can be trained on a dataset of text messages and use Prolog’s rules-based reasoning to generate responses that are relevant and coherent.
