Title Detecting the "Point of Originality" in Student Writing
Author: White, Brandon; Larusson, Johann
Abstract: This paper proposes a new method for the objective evaluation of student work through the identification of original content in writing assignments. Using WordNet as a lexical reference, this process allows instructors to track how key phrases are employed and evolved over the course of a student’s writing, and to automatically determine and visualize the point at which the student’s language first demonstrates original thought, phrased in their own, original words. After sketching the method for isolating “points of originality,” the paper provides a method for visualizing the resultant information. By visualizing otherwise subjective information in a way that is objectively intelligible, the goal provides educators with the ability to monitor student investment in concepts from the course syllabus, and to extend or modify the boundaries of the syllabus in anticipation of pre-existing knowledge or trends in interest.
