  • Patent number: 10699589
    Abstract: Systems and methods are provided for determining whether an examination prompt elicits responses of a type for which the examination prompt is designed. Word types for each of a plurality of words in a plurality of responses to the examination prompt are identified. An evaluation distribution of the identified word types is determined. Predetermined distributions stored on a computer-readable medium associated with a plurality of different response types are accessed, and the evaluation distribution is compared to each of the predetermined distributions to determine which predetermined distribution the evaluation distribution is most similar. A determination is made as to whether the most similar distribution is associated with a same response type as the type for which the examination prompt is designed. An indication is made as to whether the examination prompt is deemed to elicit responses of the type for which the examination prompt is designed.
