An approach to visualize unorganized collections of documents

In order to support search and retrieval of documents in digital libraries, this paper proposes an approach to visualize unorganized collections based on the results of two clustering algorithms namely k-means and COBWEB. These algorithms are implemented in Weka and they were chosen experimentally to produce a structure that can be explored by users in a 3D interface. Documents need to be processed before Weka can use them. We describe the main components of the proposed interface and show preliminary results of the application of those algorithms.
