    Abstract
    It has been suggested that the observed values of retrieval effectiveness that are obtained in searches of files of nearest-neighbour clusters can be explained by assuming that the pairwise inter-document similarities used to construct the clusters have been generated randomly. Such similarities are significantly different from those obtained by a random generation procedure
