Abstract
In an information processing apparatus, a first deletion unit deletes, from sets stored in a storage unit, sets having less than a threshold number of included elements and elements existing in only sets whose number is less than a threshold number of occurrences. A grouping unit generates a group of sets associated with each other in terms of commonality of elements out of the sets remaining in the storage unit. A second deletion unit deletes, with respect to each generated group, sets having less than the threshold number of included elements and elements existing in only sets whose number is less than the threshold number of occurrences, from the sets belonging to the group. An output unit outputs a list of elements included in the sets remaining in each group where there are no sets or elements that need to be deleted.
