SAWA calculates a semantic similarity coefficient between two sentences. Coefficient is expressed between "0" and "1", where: 0 means there is not semantic similarity among them; 1 vice versa.

A simple tool for sketching out ontology structures, including OWL export. Developed at the University of Manchester as a third-year project.

TurtleScript is a semantic web project to demonstrate the utility of including the Turtle RDF serialization in HTML files as a form of metadata. It is intended as proposed alternative or supplement to microformats and RDFa.

In this project we investigate the representation of tweets as RDF in order to enable flexibility in handling the information overload of those interested in collectively analyzing social media for sensemaking.

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

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/.

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.

This Java tool converts your RDF files from any RDF format to any other format. It is based on the openRDF.org Sesame project and is wrapped into one single jar file for easy usage.

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.
