Method and apparatus for analysing performance of a network by managing network data relating to operation of the network

Abstract:

A method for analysing performance of a network by managing network data relating to operation of the network is disclosed. The method comprises receiving a plurality of network data records from at least one network data source, processing the received plurality of network data records into a plurality of network data documents, each network data document corresponding to a received network data record, assembling the plurality of network data documents into document groups, generating statistical data for terms appearing in the document groups, and for at least one term, performing anomaly detection upon the statistical data for the term in the document groups, and detecting an anomaly in the term. The method further comprises performing at least one of identifying the term as an anomalous term, identifying the document group containing the anomaly as an anomalous group, and/or identifying a document containing the anomalous term as an anomalous document.
