SURVEY FRAUD DETECTION SYSTEM AND METHOD |
摘要 |
A method of filtering fraudulent responses from survey data including responses to survey questions received from survey takers and a response time for each response. For each question, any responses to the question having a response time less than a minimum time required to provide a thoughtful response are filtered from the survey data. Optionally, for each survey taker, a number of responses filtered from the survey data is determined. If this number exceeds a threshold, all responses provided by the survey taker are filtered from the survey data. The method may determine whether responses provided by each survey taker to attributes of a matrix question include a pattern. If a survey taker's responses include the pattern and were provided in less than the minimum time required to provide a thoughtful response to the matrix question, all responses provided by the survey taker are filtered from the survey data.
