A system evaluates a first data cleansing application and a second data cleansing application. The system includes a test data generator, an application execution module, and a results reporting module. The test data generator creates a dirty set of sample data from a clean set of data. The application execution module cleanses the dirty set of sample data. The application execution module utilizes the first data cleansing application to cleanse the dirty set of sample data and create a first cleansed output. The application execution module further utilizes the second data cleansing application to cleanse the dirty set of sample data and create a second cleansed output. The results reporting module evaluates the first and second cleansed output. The results reporting module produces an output of scores and statistics for each of the first and second data cleansing applications.

A system cleanses data. The system includes an input component, a pre-process component, an automated learning component, and a post-process component. The input component receives a collection of records. The pre-process component formats the collection of records and creates a plan for cleansing the collection of records. The automated learning component performs the plan and modifies the plan based on feedback from intermediate steps within the plan. The post-process evaluation component evaluates the result of the automated learning component. The post-process component determines whether to accept the result or to feed back the result to the automated learning component.
