The purpose of our study is to clarify the linguistic and conceptual vagueness that surrounds the use of “objets flottants”, in order to answer the question: How is the use of mediating objects in systemic therapeutic interventions semantically determined? To this end, we carried out a network analysis of authors and a lexical analysis. The network analysis (conducted using VOSviewer) modeled the range of the publications related to our theme, while the lexical analysis – designed with Tropes – determined terminological profiles according to epistemological affiliations. These analyses were conducted for the French- and English-speaking literature. The results show linguistic bridges and various modes of terminological usage according to authors’ theoretical affiliations.
