Open Source Prolog 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!

Linguistic Tree Constructor (LTC) is a tool for drawing lingusitic syntax trees of already-existing text. It is a syntax editor, not a text editor, so the text has to exist already. It is best suited for large-scale, rapid creation of hand-annotated treebanks. The user can define their own node categories, and can label each node with labels, also definable by the user. LTC supports "generic", X-Bar and RRG trees. Supports interlinear texts in SIL SFM format.

Jude is a rapid application development tool to develop data management applications easy to mantain for developers and easy to use for end users.

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/

ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.

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

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.

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.

EYE [1] is a reasoning engine supporting the Semantic Web layers [2]. It performs controlled chaining and it supports Euler paths [3]. Via N3 [4] it is interoperable with Cwm [5].

The Generic Eclipse Modeling System is an MDD tool for Eclipse that allows for the rapid development of GEF modeling plugins. In GEMS, developers specify rules for a domain language using a metamodel and the tool generates a plugin for the specification

A general purpose Java interface for Prolog implementations.

MotOrBAC is a tool to help you design and implement a security policy using the OrBAC (Organisation Based Access Control) model. It is developped using the OrBAC API, an implementation of the OrBAC model.

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

8. Mai 2005: We have discontinued SourceForge as a download place for our open source projects. You can now download these projects directly from the XLOG Technologies GmbH web site at http://www.xlog.ch/omonia.

A Practical Agent Programming Language

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.

AntWar! is a virtual life simulator. The player must extends the base ants classes to create their own colonys whose must survive in the warfield.

Browlser lets you view Semantic Web RDF/OWL straight from your browser. Supports SWRL rules for OWL files that also define rules for displaying the data. You can give someone a URL address which directly runs the OWL application.

A collection of tools for working with the comparative data analysis ontology including import/export facilities for common phylogenetic file formats, and also a triple-store framework.

This is a short C++/Java/C#/Python benchmark. Based on Paul Heckbert's sources. Thank you Paul!

Cedalion is a programming language that allows its users to add new abstractions and define (and use) internal DSLs. Its innovation is in the fact that it uses projectional editing to allow the new abstractions to have no syntactic limitations.

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.

Component (library, framework) refactoring may affect existing applications, where the client code used previous component versions. Our tool preserves applications binary-compatible by generating an adaptation layer out of change history.

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.

Computer Security Model Implementations for Computer Science Graduate Students and Researchers. Implementations include the Take-Grant Protection System and a Self-Organized Critical (SOC) Lattice Model for malware behavior.
