ABSTRACT:
In one general aspect, entity instances are monitored during a first interval, each entity instance being one of several types of entity instances. A first ranked list of entity instances is determined from the entity instances monitored during the first interval. The types of entity instances are ranked in the first list according to the number of times each type of entity instance occurred during the first interval and the first ranked list has a first cardinality of types of entity instances. Entity instances are monitored during a second interval. A second ranked list of entity instances is determined. The second ranked list has the first cardinality of types of entity instances. The first ranked list and the second ranked list are merged into a third ranked list of entities instances. The third ranked list has a second cardinality that is less than or equal to the first cardinality.
