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.

Framework for evaluating data cleansing applications

A system views results of a data cleansing application. The system includes a results visualization module and a learning visualization interface module. The results visualization module organizes output of the data cleansing application into a predefined format. The results visualization module displays the output to a user. The learning visualization interface module facilitates interaction with the data cleansing application by the user.

Visualization toolkit for data cleansing applications

A system evaluates a data cleansing application. The system includes a collection of records cleansed by the data cleansing application, a plurality of dirtying functions for operating upon the collection to introduce errors to the collection, and a record of the errors introduced to the cleansed collection. The plurality of dirtying functions produces a collection of dirty records.
