16. The method of claim 12 , wherein generating the correlation graph comprises: determining correlation strengths for pairs of correlated events; and adding weights to at least one of the vertices and edges of the correlation graph based on the correlation strengths.
12. The method of claim 1 , further comprising: generating a correlation graph for the set of correlated events, the correlation graph comprising vertices and edges connecting the vertices, wherein each vertex represents a particular event and each edge represents a correlation between the events represented by the connected vertices, wherein an edge is added between two vertices if there is at least one identical context identifier associated with the two events; analysing the graph to determine at least one root vertex; and determining the at least one root event among the correlated events based on the at least one root vertex.
