Abstract
A method of assisting with the construction of a tree of clusters of electronic documents, the documents being defined by predetermined attributes. The method includes, for a given cluster of documents and a given level of the tree, the following steps: a) obtaining (E300) constraints defined between at least two documents of said cluster and storing those constraints; b) constructing (E310) subclusters as a function of the constraints obtained and the attributes of the documents of said cluster; c) creating (E320) a tree level corresponding to the subclusters created; and d) selecting (E340) a created subcluster and iterating the steps a), b), c) and d) for the selected subcluster until said tree is obtained. A device for implementing the method is also disclosed.
