Abstract
A metric, such as a cosine similarity coefficient, is used to determine the degree of similarity between two responses. The assumption is that similar responses contain similar words with similar frequency counts (i.e., word lists). Word lists of the responses are used as a vector to assess the similarity between the word list for each student response and the word lists of responses having known scores. An iterative modeling process called semantic content similarity scoring, implemented by a content scoring module, augments differences among the various score-point responses by extending word lists to include, for example, synonyms of key words, key phrases (two or more words), key rubric scoring rule components, likelihood that a response would be given a specific score by a human rater. The word lists are also augmented by removing stop words.
