=== Use in industry ===
Prolog has been used in [[Watson (computer)|Watson]]. Watson uses IBM's DeepQA software and the Apache [[UIMA]] (Unstructured Information Management Architecture) framework. The system was written in various languages, including Java, {{nowrap|C++}}, and Prolog, and runs on the [[SUSE Linux Enterprise Server]] 11 operating system using [[Apache Hadoop]] framework to provide distributed computing. Prolog is used for [[pattern matching]] over natural language parse trees. The developers have stated: "We required a language in which we could conveniently express pattern matching rules over the parse trees and other annotations (such as named entity recognition results), and a technology that could execute these rules very efficiently. We found that Prolog was the ideal choice for the language due to its simplicity and [[Expressive power (computer science)|expressiveness]]."<ref name=lally/> Prolog is being used in the Low-Code Development Platform [[GeneXus]], which is focused around AI.{{Citation needed|date=November 2022}} Open source [[graph database]] [[TerminusDB]] is implemented in Prolog.<ref>{{Citation|title=terminusdb/terminusdb|date=2020-12-13|url=https://github.com/terminusdb/terminusdb|publisher=TerminusDB|access-date=2020-12-15}}</ref> TerminusDB is designed for collaboratively building and curating [[knowledge graph]]s.
