Syntax tree editor for rapid annotation of existing text
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.
ECLiPSe Constraint Logic Programming System
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.
Euler Yet another proof Engine
EYE  is a reasoning engine supporting the Semantic Web layers . It performs semibackward reasoning and it supports Euler paths .

The GNU Prolog native compiler
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.
Deductive Database with Datalog, RA, TRC, DRC and SQL
The Datalog Educational System (DES) is a deductive database with Datalog, SQL, Relational Algebra, Tuple Relational Calculus and Domain Relational Calculus as query languages developed mainly for education. It can be used from most common Prolog interpreters over any supported OS and from portable executables (Windows, Linux and MacOS).
C#Prolog -- A Prolog interpreter written in managed C#
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.
EZOP is a category representing educational system.
Amine is a Multi-Layer Platform for the dev. of Intelligent System
Amine is a Multi-Layer Java Open Source Platform dedicated to the development of various kinds of Intelligent Systems (Knowledge-Based, Ontology-Based, Conceptual Graph Based, NLP, etc.) and Intelligent Agents. See: //amine-platform.sourceforge.net/
Logic Programming and Deductive Database system (Tabled Prolog) for Unix and Windows.
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).
Jude is a rapid application development tool to develop data management applications easy to mantain for developers and easy to use for end users.
HyperSpider (Java app) collects the link structure of a website. Data import/export from/to database and CSV-files. Export to Graphviz DOT, Resource Description Framework (RDF/DC), XML Topic Maps (XTM), Prolog, HTML. Visualization as hierarchy and map.
Odin is a Tool that aims to be a didatic resource for AI Teachers. It lets students visualize PROLOG programs in 3D simulations.
MARGO (Multiattribute ARGumentation framework for Opinion explanation), written in Prolog, is the engine developed in the ArguGRID project for decision making.
OpenSHORE is an XML based Semantic Document Repository (SDR) with a free definable meta model that builds up a semantic network from sections and relations in documents. The acronym SHORE means Semantic Hypertext Object Repository.
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.
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.
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.
Regulus is a Prolog-based toolkit for building spoken dialogue systems.

Implements the stable model semantics without grounding.
s(ASP) is an implementation of the stable model semantics of logic programming. Unlike similar systems, it does not employ any form of grounding. This allows s(ASP) to execute programs that are not finitely groundable, including those which make use of lists and terms. Work on s(ASP) is supported by the National Science Foundation under Grant No. 1423419. Details of how s(ASP) works can be found in the following paper: Marple, Kyle, Elmer Salazar, and Gopal Gupta. "Computing Stable Models of Normal Logic Programs Without Grounding." arXiv preprint arXiv:1709.00501 (2017) (https://arxiv.org/abs/1709.00501).
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.
