Abstract: The present invention involves a method, a system, and software for semantic analysis of disparate data in an environment having a plurality of datasets having distinct information fields. A candidate generation module involves creating graphs with information fields from the plurality of datasets as nodes, then creating smaller graphs containing source and sink vertices based on heuristic values. An electrical network computation module involves representing graphs as an electrical circuit to calculate the voltage of each node and the current of each edge by solving a system of linear equations. A diverse subgraph generation module involves selecting paths that carry the larger amount of current and have more new nodes in an iterative process. With each iteration, the path that scores the highest marginal current per number of existing types of nodes is selected and added to the diverse subgraph.

Abstract: A method, apparatus, and article of manufacture for performing data mining applications in a relational database management system. An analytic algorithm for association is performed by the relational database management system to measure one or more associations between a plurality of items in a stream of transaction data stored in the relational database, wherein the analytic algorithm for association creates at least one analytic model within an analytic logical data model from data residing in the relational database.
