Open Source Prolog Artificial Intelligence Software

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!

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.

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.

A group of systems for building network-oriented intelligent agents, consisting an agent communications infrastructure, April - an agent construction programming language, Go! - a logic programming language and DialoX - an XML-based user interface engine

Prolog+CG is a Java implementation of Prolog with extensions implementing a subset of the Conceptual Graph (CG) theory of John Sowa. CGs are first-class datatypes on a par with terms. Object oriented extensions are also included.

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/

DLog is an Description Logic ABox reasoner that uses resolution. The basic idea is that a DL knowledge base is transformed into a Prolog program without any knowledge on the content of the ABox. The answers are obtained during normal Prolog execution.

A lightweight IDE for Artificial Intelligence. Started as GUI for the Euler reasoning engine. The sources can be N3, RDF, OWL, UML, eCore, plain XML or XSD, files or URL's. Wraps Drools (or CWM, FuXi) as N3 rules engines. Model based app. generation.

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.

PyCLP is a Python library to interface ECLiPSe Constraint Programmig System. This module try to implement a pythonic interface to ECLiPSe ( http://www.eclipseclp.org ) by compromising on a little bit on performance.

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.

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

The RoboLog Soccer Library is a project to provide a library for RoboCup Simulation League clients. RoboLog can be used as an interface from Soccer Server to both C and Prolog.

TRINDIKIT is a toolkit for building and experimenting with dialogue systems based on information states, that has been developed in the TRINDI and SIRIDUS projects.

Weapon-classifying expert systems for melee weapons and firearms.

anpe is clients/server Ada/Prolog system for natural language traitement with Prolog Engine and Artificial Neural Network with Ada.

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).

AI Now is an open source endeavour to create a general purpose Artificial Intelligence. The plan is to implement a modular architecture to incorporate AI theories as they are developed. This will provide a growing platform to test new AI theories.

Artificial Intelligence program - keyword based chat, personal voice in/out, animated 3D character, natural language recognition and translation, neural network based strong AI, personality, tone recognition

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.

A project which uses existing speech recognition and speech translation resources to build conversation partners for beginning language students, based on the idea of a "translation game".

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