System for decomposing events and unstructured data

A system texecutes automatic attribute inference and includes: a processor; a memory coupled to the memory; a first engine that executes automatic attribute inference; an extraction engine in communication with a managed infrastructure and the first engine, the extraction engine configured to receive managed infrastructure data; and a signaliser engine that includes one or more of an NMF engine, a k-means clustering engine and a topology proximity engine, the signaliser engine inputting a list of devices and a list a connections between components or nodes in the managed infrastructure, the signaliser engine determining one or more common characteristics and produces one or more dusters of events.
