Abstract: An information resource taxonomy system, including a data collector for collecting information resources from a communications network; and a taxonomy generator for generating a taxonomy represented by a hierarchy of resource clusters, using cluster criteria generated from the collected resources. The system includes an editor for editing the criteria, and a renderer for generating linked document data for displaying the hierarchy. A parallel cluster search system is used to evaluate clusters in parallel. The system also includes a parallel classifier for classifying further collected resources.

Abstract: The fault system includes an interface for accessing first data fault representative of faults in the reported by users of mobile stations of the network, an interface for accessing second fault, data representative of faults in the network determined by a network analysis system, and pattern matching device for allocating the first and second fault data to fault patterns, representative of faults having at least one common characteristic. The common characteristics is geographic location and fault type. The fault system further includes pattern generation device for generating the fault pattern using respective fault templates to allocate the fault data to the fault patterns.
