  • Publication number: 20170161759
    Abstract: An approach to automatically generating a survey. The approach collects input information from a survey designer and uses the input to generate sections for the survey. The approach then selects question from related archived surveys and generates new questions from internal and/or external data sources to assemble the survey. The approach can perform the section generation analysis and the question selection/generation automatically and/or tuned by a survey designer. The approach distributes the completed survey to survey takers and feedback is provided based on metrics associated with characteristics exhibited by the survey takers while taking the survey. The feedback allows the approach to improve survey quality.
