Abstract

Programming by example enables users to transform data formats without coding. To be practical, the method must synthesize the correct transformation with minimal user input. We present a method that minimizes user effort by color-coding the transformation result and recommending specific records where the user should provide examples. Simulation results and a user study show that our method significantly reduces user effort and increases the success rate for synthesizing correct transformation programs by example.
