Patent ID: 8442073

Claim:
A method for analyzing a communication network comprising nodes communicating with each other via messages, the method comprising: detecting messages that are exchanged between the nodes of said communication network; storing said messages in a message list memory; identifying communication links within the network, each communication link being identified between a source node and a destination node if and only if a message has travelled on the link from the source node to the destination node; for each message that has been stored in the message list memory, identifying a content of the message; performing a topic discovery on the basis of the content of all of said messages; performing a segmentation of a global network graph representing said communication network into topic sub-graphs depending on the discovered topics, each sub-graph including at least two nodes and the communication link connecting the nodes; calculating intra-topic network properties of the nodes within their respective sub-graphs; and calculating inter-topic network properties of the nodes with regard to all sub-graphs by calculating an inter-topic centrality of each node proportionally to a number of sub-graphs to which the respective node is a member of.
