Open Source Prolog Software Development Software

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

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.

C#Prolog -- A Prolog interpreter written in C#. Can easily be integrated in C# programs. Characteristics: reliable and fairly fast interpreter, command line interface, Windows-interface, builtin DCG, XML- and JSON-predicates, SQL-predicates, extendible.

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.

weed is a visually appealing theme for the irssi IRC client, inspired by XChat. It offers a modern and customizable interface, enhancing the user experience for irssi users who prefer a more aesthetic layout.​

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.

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!

ADP (Another Data Processor) is a programing language that is designed for Web database programing. It is a scripting language and a lightweight programming language in which it is possible to mix SQL easily. It is easy to install. ADP is base on Prolog. But ADP uses only the backtrack and unification. The syntax is original and likes a another scripting language, supports method call.

Prosper is a web application development framework to augment Prolog applications with a web interface. It supports control flow in visual logic and promotes a clear separation of model from view.

The Prolog Expert System Shell (PESS) is a software that generates ES using basically two components: Knowledge Base, used by the ES to guide its decisions making, and Inference Machine, cable of collection the rules and generating new facts.

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 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

Sun Profile Project.

XGP is an integrated development environment that extends GNU Prolog to work with Cocoa under Macintosh OS X. It provides user interface and graphics facilities largely compatible with MacProlog32 by LPA. Requires Mac OS X version 10.2.1 or greater.

PyCDep is a tool to analyze include dependencies between files in C and C++ programs. PyCDep itself is written in python. It dumps all the facts in a prolog database which can be queried. Visualization is possible by dumping graphviz (.dot) files.

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.

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.

PrologTab plugin integrates a Prolog inference engine with the Protege-2000 knowledge base.

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

Prolog compiler and interpreter for the .Net 2.0 framework.

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.

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.
