The aim of this article concerns adaptive and personalized navigation in a cultural heritage database. The theoretical grounding of the proposition relies on cognitive science, particularly constructivism and enaction. The navigation is conducted via an intelligent interface through a 3D "living" museum metaphor. The purpose of this interface is to recommend dynamic cultural heritage objects according to a user profile that is computed online from the interactions that a user has with these objects. To this end, objects are linked to semantic structures that represent relations between cultural heritage concepts. The user profile is described in terms of cultural heritage interests. A prototype of this principle is used to evaluate some of the basic hypotheses of this proposition. Keywords visual metaphor · real-time adaptation · profiling techniques · personalized database exploration · virtual museum 1 Preamble for the reviewer, relative to UMUAI submission-What is the main research question that your planned submission addresses ? How can we personalize cultural heritage data exploration "in line " through a co-construction paradigm (i.e., during the exploration and not from a predefined user profile)?-What makes your research results important and worth being reported in a top-ranked journal (as opposed to a conference) ? This paper presents an global study compound of some results: 1) a model that includes the L. Rajaonarivo
