Analyzing data. A method includes obtaining a set of a plurality of data entities and relationships. The method further includes subdividing the set of a plurality of data entities and relationships into a plurality of composite collections of data entities and relationships. Each composite collection within the plurality of composite collections disambiguates the composite collection, within a relationship scope, from ambiguities in the set of a plurality of data entities and relationships. The method further includes providing one or more of the plurality of composite collections of data entities and relationships to a data mining engine. Each composite collection of data entities and relationships is provided as a separate unit to the data mining engine.
