Abstract:
1. A computer implemented method for analyzing structured data extracted from a network packet stream, comprising: passively capturing messages in a network packet stream; extracting business data from the captured messages, the extracted business data including semantic relationships contained in the captured messages; processing the extracted business data to conform to a data model format that indicates one or more of the semantic relationships of an individual captured message and one or more of the semantic relationships between two or more of the captured messages, the processing further including performing a dependency analysis on at least one variable based on the semantic relationships and building an approximation of an analytic PDF; applying one or more statistical modeling techniques to the processed extracted business data to identify a pattern corresponding to an event; identifying a subsequent occurrence of the event by detecting the pattern in subsequently captured messages; and exporting the detected event via a network.
