##FOX - Federated Knowledge Extraction Framework FOX is a framework that integrates the Linked Data Cloud and makes use of the diversity of NLP algorithms to extract RDF triples of high accuracy out of NL. In its current version, it integrates and merges the results of Named Entity Recognition tools. Keyword Extraction and Relation Extraction tools will be merged soon.
