Abstract

Often, academic programs require students to write a thesis or research proposal. The review of such texts is a heavy load, especially at initial stages. One feature evaluated by instructors is coherence, i.e. the interrelationship of the various elements of the text. We present a coherence analyzer, which employs latent semantic analysis (LSA) to mine existing corpora to further assess new drafts. We designed the analyzer as part of an Intelligent Tutoring System, considering seven common sections. After mining domain knowledge, experiments were done on graduate and undergraduate corpora to define a grading scale. Another experiment that involved human reviewers was set to validate the process. The technique allowed evaluating the coherence of the different sections, reaching an acceptable result and hinting that the level reached so far is adequate to support online review. An innovative exploration across sections was performed, uncovering a consistent interrelationship, according to methodology authors.
