Abstract:
A computer-implemented method comprising:inputting a first data model for a plurality of cooked transactional variables into a system, the cooked transactional variables abstracted from a plurality of raw transactional variables organized into a hierarchy of nodes, the raw transactional variables based on a data set comprising a plurality of records, each record having a value for each raw transactional variable, and a concept is defined over the hierarchy of nodes as one of a root node of the hierarchy, a node in the hierarchy, and a set of nodes in the hierarchy having a same parent node; where each cooked transactional variable corresponds to an unrefined concept after the hierarchy has been successively refined a number of times, a refined concept defined as an initial concept refined into two subsequent concepts such that one of the two subsequent concepts is a most populous node of the hierarchy as measured by the plurality of records having non-zero values for a raw transactional variable corresponding to the most populous node and the two subsequent concepts contain a same set of nodes of the hierarchy as the initial concept does; determining a type of the first data model; generating a second data model for the plurality of raw transactional variables based on the first data model and the type of the first data model; and outputting the second data model.
