Abstract
Systems and methods are provided for a computer-implemented method of providing a score that measures an essay's usage of source material provided in at least one written text and an audio recording. Using one or more data processors, a determination is made of a list of n-grams present in a received essay. For each of a plurality of present n-grams, an n-gram weight is determined, where the n-gram weight is based on a number of appearances of that n-gram in the at least one written text and a number of appearances of that n-gram in the audio recording, and an n-gram sub-metric is determined based on the presence of the n-gram in the essay and the n-gram weight. A source usage metric is determined based on the n-gram sub-metrics for the plurality of present n-grams, and a scoring model is used to generate a score for the essay based on the source usage metric.
