The aim of this paper is to contribute to the construction of a human and social sciences (HSS) on-line dictionary. The latter is Wiki-oriented. It takes into account the multicultural aspect of the HSS as well as the ISO 1951 standard. The latter has been defined by the ISO Organization in order to harmonize the presentation of specialized/general and multilingual/monolingual dictionaries into a generic structure independent of the publishing media. The proposed Wiktionary will allow HSS researchers to exchange and to share their knowledge regardless of their geographical locations of work and/or of residence. After the conceptual description of this dictionary and the presentation of the mapping rules to Wiki semantic concepts, the paper will present an overview of the prototype that has been developed.
