Open Source Prolog Artificial Intelligence Software for BSD

GNU Prolog is a free implementation (under GPL) of the logic programming language PROLOG. It can compile to native machine code which is extremely fast in execution. Another feature is the included constraint solver.

Logic Programming and Deductive Database system (Tabled Prolog) for Unix, Mac, and Windows.

The ECLiPSe Constraint Logic Programming System is designed for solving combinatorial optimization problems, for the development of new constraint solver technology and their hybrids, and for the teaching of modelling, solving and search techniques.

ALPprolog is a Prolog implementation of an action programming language. With ALPprolog you can program strategies for autonomous agents in dynamic domains like e.g. the Wumpus world.

Amine is an Artificial Intelligence Multi-Layer Java Open Source Platform dedicated to the development of various kinds of Intelligent Systems and Agents (Knowledge-Based, Ontology-Based, Conceptual Graph -CG- Based, NLP, Reasoning and Learning, Natural Language Processing, etc.). Ontology, KB can be created and manipulated with various processes. CG theory is used as the main knowledge representation language. Amine provides two languages: PROLOG+CG which extends PROLOG with CG and Amine modules, and SYNERGY which is a visual activation/propagation based language. CGs are considered by SYNERGY as activable/executable graphs. See for more detail: //amine-platform.sourceforge.net/

Flora-2 is a powerful knowledge representation and reasoning system designed for building knowledge-intensive applications. It is based on F-logic, HiLog, Transaction Logic, and also supports defeasible reasoning. Applications include intelligent agents, Semantic Web, ontology management, and more. If you use Flora-2 and like it, please acknowledge it in your project!

The Yap Prolog System is a ISO-compatible high-performance Prolog compiler. Yap is widely considered one of the fastest available Prolog systems. Yap supports coroutining, CLP(QR), CHR, and depth-bound search. Tabling and parallelism are in development.

A Practical Agent Programming Language

A Prolog expert system supporting querying and extending the knowledge base from a command-line interface using a format oriented on natural language, with the aim of being maintainable by the domain expert (i.e. without requiring programming skills).

This project assembles the implementations of inference engines for CHORD, an object-oriented extension of CHRD.

This project provides a tool (developed by the ArguGRID project) that implements different dispute derivations for assumption-based argumentation. It also computes a dialectical structure of arguments. Users have full control over selection functions and

A framework for building, deploying and managing well-described REST-ful Web services, including REST-ful Web Services realizations for RSS, XML Topic Maps, Structured Arguments, and Workflow.

The CommGen platform is intended to be a simple, scalable integration platform for small to medium problem sets. The architecture is simple, consisting of a distributed kernel, distributed O/S, agent and application layer.

Implemented in Flora-2/XSB, F-OWL is an inference engine for the standard Web Ontology Language OWL. A set of Java API is provided for applications to assert and query OWL ontology statements.

Fi-shell is a front-end to your system shell. It provides nonblocking i/o (concurrency) and pattern maching that is both easy to remember and readable (logic programming)

Flipper is a program that does randomised local search for satisfiability of 3 variable prenex sentences in the pure predicate calculus. It does so by proving satisfiability relative to given decidable theories.

A modular language generator based on the theory of Functional Grammar (FG) by Simon C. Dik. Implemented using Java for the user interface, ANTLR for the input format parser and Prolog for the grammar and lexicon module, treating underlying linguistic st

GASPAR implements an dialectical argumentation framework for instantiating the artificial intellect of a software agent. In this artilect, motivations are represented in mental faculties which argue why and how these motivations can be adopted.

This project is about implementing a logic-programming based, reasoning engine for an agent. We started with an implementation of the iff-proof procedures, by Kowalski and Fung, as an any-time algorithm written in Prolog.

GGPrayer is an AI capable of playing any game described in the GameDescriptionLanguage defined in http://games.stanford.edu/.It uses Java to communicate to the gameserver and Prolog for reasoning. Info: http://bruno-wp.blogspot.com/search/label/Software

N.B. THE PROJECT HAS BEEN MOVED TO GITHUB https://github.com/jiprolog/ JIProlog is a cross-platform pure Java 100% Prolog interpreter that integrates Prolog and Java languages in a very fashinating way. JIProlog is compliant with the major Prolog interpreters. It supports most of ISO Prolog specifications and the most common and used built-in predicates, JIProlog allows to call Prolog predicates from Java without dealing with native code (JNI or JNA) and allows to invoke Java methods from Prolog in the same way you call predicates.

JLog is a Prolog interpreter written in Java. It is fast and perfectly suited for education. It includes source editor, query panels, online help, animation primitives, and a GUI debugger. JScriptLog is Prolog in JavaScript.

JPIE is an implementation of an Open Source Java to Prolog/Prolog to Java interoperability mecanism based on the Java VM.

JinnIde is a plugin that allows using Jinni Prolog, now also hosted here on this site (with open source license!), within the confines of an IDE integrated in JEdit.

Use a language CycL or KIF to represent shared ontological integration with a first person MOO system to provide debugging and agent facilities.
