1. A computer implemented method for providing information related to a task in a case management system configured to process a plurality of cases, the computer implemented method comprising: identifying among the plurality of cases, by a server, a plurality of case clusters, wherein each of the plurality of case clusters is associated with a case similarity factor shared by at least two cases of the plurality of cases, and the case similarity factor is related to at least one of geographical case specific parameters and contextual case specific parameters; for a case cluster of the plurality of case clusters, identifying, by the server, a plurality of task clusters, wherein each of the plurality of task clusters is associated with a task similarity factor shared by at least two tasks of the task cluster, and tasks of the plurality of task clusters are performed on cases of the case cluster, and wherein for the case cluster of the plurality of case clusters, the task similarity factor is related to the case similarity factor and task specific parameters and the identifying the plurality of task clusters comprises: based on the task similarity factor, using task metadata, case metadata, and semantic entities to categorize the tasks into the plurality of task clusters, wherein the semantic entities are extracted from case documents used in performing the tasks; analyzing, by the server, reports and documents used to perform the at least two tasks of the task cluster sharing the task similarity factor; and when performing a task sharing the task similarity factor with the at least two tasks, providing, by the server, at least one report based on the reports and at least one summary based on the documents.
