Beyond classical techniques to explore a document collection such as Information Retrieval and graphical visualisation we present in this paper an analytic view which combines the expression of a goal-centered query and the construction of a virtual multimedia document. Building this synthetic document is considered as a complex adaptation problem. We propose a first approach to characterise this process and introduce the required knowledge. An application to the medical field and in particular the Tissue MicroArrays technology allows us to illustrate the interest of this approach. A preliminary validation of the proposed concepts is performed by means of the TreeMaps tool from the University of Maryland.
