Open Source Java Semantic Web Software - Page 3

This project is dedicated for semantic annotation of video and image files and development of a unified page ranking for them.

A number of implementations of the W3C POWDER Recommendation

Webtracks’ objective is to develop an approach and mechanism for constructing and propagating structured information to describe the linkage between distributed research objects in the context of academic activities.

Spreadsheet-to-RDF wrapper capable of transforming spreadsheets to arbitrary RDF graphs; supports mapping language with powerful formula expressions as you know from Excel, local/remote Excel/ODF/CSV, SPARQL service - source available at https://github.com/theandyl/xlwrap

Some scenarios for neuroinformatics experiments are saved in standard XML document. This program should be able to parse almost any scenario so far to make a full-valuable RDF file, where every pieces of scenario has their own URI. This project is from University of West Bohemia in Czech republic, required to Fundamentals of Software Engineering (KIV/ZSWI).

e-NVISION, STREP project of the 6th FP (http://www.e-nvision.org/). This site contains the open-source software developed in the project. Keywords: e-Business, ontologies, platform, semantic web services, BPEL processes.

*** IMPORTANT NOTICE *** The source code of the earliest version of the EARMARK Data Structure is now available at http://www.github.com/essepuntato/EarmarkDataStructure Even if the SourceForge repository is still active, it concerns old versions of the API and it is not maintained anymore. *** SERVICE DESCRIPTION *** Extremely Annotational RDF Markup (EARMARK) is an ontological approach to the specification of markup structures on text content. It allows not only documents with single hierarchies (as with XML) but also multiple overlapping hierarchies.

foaf4java - Based on the Jena Semantic Web framework (http://jena.sourceforge.net), “FOAF for Java” is a toolkit for handling FOAF profiles easily, by Safelayer (http://labs.safelayer.com). Find more details about FOAF at http://xmlns.com/foaf/spec/.

This project is a reasoner for the description logic EL+. It computes the concept subsumption hierarchy. It is an OWL 2 EL reasoner.

Metadata.net is a collection of website components and tools for creating and using metadata produced by the eResearch Group at ITEE, University of Queensland.

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. If the user rejects it, the user has to give a counterexample to this question, i.e., an individual that is an instance of C1, C2 and not C3. When all such questions (about some initially given classes) have been answered, the ontology is complete with respect to the application domain.

owl-indexer generates full text index of OWL literal via either Apache Lucene or Sphinx Search. It is based on OWL API (https://github.com/owlcs/owlapi).

SpatiumCube is open source technology for the easily development of Spatial Data Infrastructures (SDIs) and services over them. It includes software, stylesheets, ontologies, and other technology elements for the development of SDIs.

The tRDF framework provides tools to deal with the trustworthiness of RDF data.

This library facilitates a creation and management of OWL 2 ontology that describes a web service as defined in WSDL Version 2.0: RDF Mapping W3C specification. While the specification is based OWL 1.1 version, the library uses "The OWL API" which is OWL 2 based.

This tool converts Common Infomation Model (CIM) into an ontological representation in OWL language.
