Abstract
An analysis of the rank‐frequency distribution of the EURATOM‐thesaurus was carried out. Zipf's law (a hyperbolic function) was not found to be suitable for this distribution, and an exponential law was used. The total entropy of the thesaurus calculated by means of this exponential function was found in good agreement with the actual entropy of the thesaurus. The exponential function may provide a criterion to ‘revise’ some zones of thesauri.
