Abstract. We present in this paper, a new model for document hierarchical clustering, which is inspired from the self-assembly behavior of real ants. We have simulated the way ants build complex structures with different functions by connecting themselves to each other. Ants may thus build ”chains of ants” or form ”drops of ants”. The artificial ants that we have defined will similarly build a tree. Each ant represents one document. The way ants move, disconnect or connect themselves depends on the similarity between these documents. The result obtained is presented as a hierarchical structure with a series of HTML files with hyperlinks.
