Systems and methods are provided for managing information networks. A delta causality matrix is generated based on newly discovered topology changes in an information network. The delta causality matrix specifies changes in problem-symptom relationships of a causality matrix associated with constituent objects in a previous topology of the information network. The delta causality matrix is utilized to modify at least one context which comprises a first set of related symptoms and problems associated with the constituent objects in the previous topology of the information network. The modified context includes a second set of related symptoms and problems associated with constituent objects of the modified topology of the information network. An event correlation operation is performed utilizing the modified context and active symptoms detected in the information network, to determine at least one problem which has a symptom signature that corresponds to the set of current symptoms.
