A SKOS radiation safety thesaurus for people living in contaminated territories

Abstract

During the long-term period of a nuclear disaster, people living in contaminated territories need to gain knowledge in order to take protective actions. While existing representations of this knowledge are designed for experts, we propose a thesaurus of radiation safety built for the lay people. We present a methodology to extract such a thesaurus from a set of documents addressed to non-experts. Extension of the corpus and implementation of more automated processes are still required to improve the resulting thesaurus.
