Abstract: Based on the utilization relation between users and granulars of big data for a given task,a definition for the cooperative unit is established,and its aggregation is termed the cooperative combination.Criteria are outlined to define a complete cooperative combination based on its inclusion of all elements within the utilization relation.Additionally,a cooperative combination is designated as the simplest complete cooperative combination if it is complete and none of its proper subsets share this property.Finally,the concept reduction algorithm within formal concept analysis is applied to identify the simplest complete cooperative combination for a given task.

Key words: Big data, Utilization relation, Cooperative unit, Cooperative combination, Complete cooperative combination, Simplest complete cooperative combination, Formal concept, Concept reduction
