jCOLIBRI: an object-oriented framework in Java for building Case-Based Reasoning (CBR) systems. Supports Textual-CBR, Knowledge Intensive CBR with Description Logics reasoning through Ontologies, Web interfaces, evaluation of the generated applications,

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.

...Usually, these are very time-consuming and complex tasks because the features have to be manually crafted. The features are aggregated, combined or split to create features from raw data. This project makes use of ontologies to automatically generate features for the ML algorithms. The features are generated by combining the concepts and relationships that are already in the knowledge base, expressed in form of ontology.

...LogMap extract mappings between classes, properties and instances. To the best of our knowledge, LogMap is one of the few matching systems that: 1. can efficiently match semantically rich ontologies containing tens (and even hundreds) of thousands of classes, 2. incorporates sophisticated reasoning and repair techniques to minimise the number of logical inconsistencies, and 3. provides support for user intervention during the matching process (see Web interface).

A Java interface and implementation for the W3C Web Ontology Language (OWL), used to represent Semantic Web ontologies. The API is focused towards OWL 2 and offers an interface to inference engines and validation functionality.

This project has started the design of a module language that allows composition of ontologies in a more elaborate way than the mere import of ontologies.This project is a French-Brazilian collaboration supported by Informatics Center-UFPE and INRIA.

This project has moved to https://github.com/lmazuel/onagui - OnAGUI (Ontology Alignment Graphical User Interface) is a project of alignment helper and viewer. You can edit ontology (SKOS, OWL) and edit alignment between concept of these ontologies. In addition, you can make automatic discovery of alignment, using different kind of algorithm. This work was initiated by Jean Charlet (http://www.limics.fr/index.php/annuaire), designed and developped by Laurent Mazuel on a post-doctoral project. By now, this project becomes Open Source, and continues to be enhanced by J.Charlet and L.Mazuel.

S-Match is a semantic matching framework. S-Match takes any two tree like structures (such as database schemas, classifications, lightweight ontologies) and returns a set of correspondences between those tree nodes which semantically correspond to one another. S-Match contains implementations of the semantic matching, minimal semantic matching and structure preserving semantic matching algorithms. S-Match applies as a solution in many fields, including: information integration, ontology evolution and alignment, peer-to-peer information sharing, digital libraries integration, web service composition, agent communication, and query answering on the web. ...

The project has moved to github https://github.com/EnFlexIT/AgentWorkbench Agent.GUI is a simulation framework and toolkit based on the JADE framework. It provides functionalities for time aspects, agent-environment interaction, visualization and load balancing, Furthermore, the included application focuses the usability for end users.

DL-Learner is a tool for learning concepts in Description Logics (DLs) from user-provided examples. Equivalently, it can be used to learn classes in OWL ontologies from selected objects. As of August 2014, the source code management of DL-Learner has moved to Github: https://github.com/AKSW/DL-Learner Please use this for the latest code and issue tracking and the website (http://dl-learner.org) for general information.

OntoComP is a Protégé 4 plug-in for completing OWL ontologies. It enables the user to check whether an OWL ontology contains "all relevant information" about the application domain, and extends the ontology appropriately if this is not the case. It achieves this by asking the user questions of the form "are instances of classes C1 and C2 also instances of class C3?". If the user confirms such a question, then a new axiom of the application domain that does not follow from the ontology has been discovered, and it is added to the ontology. ...

A diff/merge of two OWL ontologies.

KADMOS provides a lightweight API for alignment of OWL 2 ontologies. It is based on the OWL API v3.

A multi-agent architecture for building interactive dramas. It uses the Jason's BDI engine, being the Jason's agent-oriented programming language utilized for performing the drama management and for authoring behaviors for the characters.

MAPONTO is an interactive tool for discovering semantic mappings between database schemas and ontologies as well as between different database schemas. The tool analyzes semantics in the input schemas and ontologies for generating semantic mappings.

Ontology MApping FRAmework Toolkit allows to create semantic relations between two (source and target) ontologies, and apply such relations in translating source ontology instances into target ontology instances.

A library to support spread activation techniques over ontologies.

The goal of this project is to build a very large ontology. What is intended is a multiple inheritence taxonomy with properties. Usual ontologies like OpenCyc or ThoughTreasure weights a few megabytes. The project will build a 100 megabyte ontology.

VINE is a vocabulary Integration Environment Tool, developed at MMI. It allows to create fast mappings and alignments from ontologies in OWL. VOC2OWL is a tool to create ontologies from ASCII files. They are both JAVA based and are delivered as a Rich Cl

NaturalOWL generates descriptions of individuals and classes from OWL ontologies that have been annotated with linguistic and user modeling resources expressed in RDF. Currently it supports English and Greek. NaturalOWL can be used as a Protégé plugin.

Protege is a free, open-source platform that provides a suite of tools to construct domain models and knowledge-based applications with frame-based and Semantic Web ontologies.

OntoBridge is a java library that eases the management of ontologies. It is based on Jena, uses simple textual identifiers to work with the ontology elements, loads local/online OWL ontologies, supports Pellet/DIG, and includes several examples.

This is a distributed reasoning system that supports inference with multiple, modular ontologies.

OntoExtractor is a way of building ontologies that proceeds in a bottom-up fashion, defining concepts as clusters of concrete XML objects. From a set of XML documents the application generates a taxonomy. OntoExtractor has been developed so far by the Kn

CMS (CROSI Mapping System) is a structure matching system that capitalizes on the rich semantics of the OWL constructs found in source ontologies and on its modular architecture that allows the system to consult external linguistic resources.
