摘要： A network analysis system which obtains parameter data generated by equipment of a telecommunications network. The parameter data represents operational parameters of the network. The system processes the parameter data to generate symptom data from test procedures applied to the parameter data. Fault data is generated, which is representative of faults which may have occurred, on the basis of the symptom data and relationship data representative of the relationship between the symptom data and the faults. The relationship between a symptom and a fault represents the likelihood of the system being caused by the fault. The system also generates occurrence data, which is representative of faults which probably have occurred, on the basis of the fault data.

摘要： A search engine and system for data, such as Internet web pages, including a query analyser for processing a query to assign respective weights to terms of the query and to generate a query vector including the weights, and an index network responsive to the query vector to output at least one index to data in response to the query. The index network is a self-generating neural network built using training examples derived from a feature extractor. The feature extractor is used during both the search and training phase. A clusterer is used to group search results.

摘要： A network fault system (2) for mobile telecommunications network which includes a first interface (8, 14) for accessing first fault data representative of faults reported by users of mobile stations of the network a second interface (12, 14) for accessing second fault data representative of faults in the network determined by a network analysis system (10), and pattern matching means (14, 24) for allocating the first and second fault data to fault patterns representative of faults having at least one common characteristic.
