Wikimeta semantic labelling tool: http://www,wikimeta.org
Wikimeta is a semantic tagging and annotation architecture built from NLGbAse metadata. Wikimeta allows you to incorporate semantic knowledge within your documents, website, content management system, blog or application. Wikimeta is fully compatible with the LinkedData Network, including DBPedia, Geonames, CIAFactbook, Wikicompanies and more. Wikimeta is fully multilingual, and can annotate text content in English (beta), and French (beta).

This tool his the co-reference detector deployed during the CoNLL Shared task 2011 by our team at the École Polytechnique de Montreal. Our system integrates a multilayer perceptron classifier in a pipeline approach. We describe the heuristic used to select the pairs of coreference candidates that are feeded to the network for training, and our feature selection method. The features used in our approach are based on similarity and identity measures, filtering informations, like gender and number, and other syntactic information. It's planed to integrate this fonctionality into the NLGbAse framework.

Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. More specifically, Wikipedia defines Linked Data as "a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF."
