The proposal examines the nature of the political discourse of international organizations (IMF , world Bank , the UN , European Union , African Union , The Arab League, etc.). The study originates from a fundamental paradox: how can we use the same descriptive linguistic tools which we use in analyzing the production of sense for the production of non-sense characterizing this type of discourse? The corpus analyzed is a collection of texts produced by the African Union. The high frequency of words and terms occurring in this type of production contributes in loosing their meaning which is contrary to the appreciation of terms occurring in an expert discourse for information retrieval or lexical resources purposes where the high frequency of a term consolidates its belonging to a specific field of knowledge. How can this paradox be explained? The full paper will report on the results of our analysis.
