PowerLoom uses a fully expressive, logic-based representation language (a variant of KIF), and it uses a natural-deduction-style backward and forward chainer as its inference engine. http://www.isi.edu/isd/LOOM/PowerLoom/ command java_api lisp_api cpp_api Inference Engine TouchGraph TouchGraph is a set of interfaces for Graph Visualization using spring-layout and focus+context techniques. http://www.touchgraph.com apache java_api Graph Visualization JViews http://www.ilog.com/products/jviews/ java_api Graph Visualization CLIPS http://www.ghg.net/clips/CLIPS.html publicdomain c_api Inference Engine eclipse extensible Interactive Development Environment platforma http://www.eclipse.org open gui Interactive Development Environment Jikes open source Java compiler http://www.ibm.com/developerworks/oss/jikes/ open Compiler Chaeron Global Positioning System (GPS) Library Java interface to GPS units, including a GUI and the ability to save results in an XML format http://www.chaeron.com/gps.html#JavaLibrary gpl java_api gui GPS API Uml2Daml Converter a GUI application for automated transformation of UML 1.4 class diagrams (in XMI 1.1) in DAML+OIL or RDFS ontologies http://freshmeat.net/projects/ju2d/ gpl gui Import RDF API for PHP (RAP) RDF API for PHP is a software package for parsing, searching, manipulating and serializing RDF models. http://www.wiwiss.fu-berlin.de/suhl/bizer/rdfapi/ gpl php_api RDF Parser RDF Query InferEd RDF editor with inference http://www.intellidimension.com/pages/site/products/infered/default.rsp gui RDF Authoring Inference Engine Semantic Web Inference using Haskell (Swish) a software package being developed to conduct experiments in using the programming language Haskell as a basis for performing inference on Semantic Web data http://www.ninebynine.org/Software/swish-0.1.html Vampire an experimental theorem prover for first-order classical logic http://www.cs.man.ac.uk/~riazanoa/Vampire/ Inference Engine OWL Plugin for Protege 2000 a plugin for Protege 2000 that allows users to read, edit, and generate OWL ontologies http://protege.stanford.edu/plugins/owl/ gui Ontology Editor RDF I/O (Rio) fast and compact parsers and serializers for RDF/XML, N-Triples, and N3, originally developed for Sesame http://sourceforge.net/projects/sesame/ open java_api RDF Parser WSDL to DAML-S Converter http://www.daml.ri.cmu.edu/wsdl2damls/ dbview export an SQL database as RDF over HTTP http://www.w3.org/2000/10/swap/dbork/dbview.py open Database Interface Surnia a reasoner for OWL Full based on the first-order theorem prover Otter http://www.w3.org/2003/08/surnia/ Inference Engine Pellet an OWL DL reasoner based on the tableaux algorithms developed for expressive Description Logics http://www.mindswap.org/2003/pellet/ Inference Engine RDF Twig RDF Twig is a set of XSLT extension functions for Saxon and Xalan to provide access to RDF graphs stored in the Jena repository http://rdftwig.sourceforge.net/ RDF Transformation IHMC Concept Mapping Software empowers users to construct, navigate, share, and criticize knowledge models represented as Concept Maps http://cmap.coginst.uwf.edu/ gui Graph Visualization Lexicon-Based Ontology Mapping Tool lexicon-based ontology mapping tool http://projects.teknowledge.com/DAML gpl prolog_api Ontology Translation Semantic Query Interface in Restricted English (SQIRE) a restricted English query interface for Semantic Search http://projects.teknowledge.com/DAML www Search Engine Python an object-oriented interpreted programming language http://www.python.org Programming Language X-Smiles Java-based XML browser, supporting XForms and other specifications http://www.x-smiles.org/ open gui Samizdat generic RDF-based engine for building collaboration and open publishing web sites http://www.nongnu.org/samizdat/ gpl www Galax an open-source implementation of XQuery 1.0 http://db.bell-labs.com/galax/ open OWLP a parser for OWL Lite and OWL DL, using the Galax XQuery implementation.
