SHELDON: Semantic Holistic framEwork for LinkeD Ontology data

SHELDON is a framework that builds upon a machine reader for extracting RDF graphs from text so that the output is compliant to Semantic Web and Linked Data patterns. It extends the current human- readable web by using semantic best practices and technologies in a machine-processable form. Given a sentence in any language, it pro- vides different semantic tasks as well as nice visualization tools which make use of the JavaScript infoVis Toolkit and a knowledge enrich- ment component on top of RelFinder. The system can be freely used at http://wit.istc.cnr.it/stlab-tools/sheldon.
