The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-23878-9_20Proceedings of 12th International Conference IDEAL, Norwich, UK, September 7-9, 2011.We describe an approach taken for automatically associating entries from an on-line encyclopedia with concepts in an ontology or a lexical semantic network. It has been tested with the Simple English Wikipedia and WordNet, although it can be used with other resources. The accuracy in disambiguating the sense of the encyclopedia entries reaches 91.11% (83.89% for polysemous words). It will be applied to enriching ontologies with encyclopedic knowledge
