UKP-BIU: Similarity and Entailment Metrics for Student Response Analysis.
Torsten Zesch, Omer Levy, Iryna Gurevych, and Ido Dagan. SemEval 2013. [pdf] [slides]
Given a question, a reference answer, and a student’s answer, the task is to determine whether the student answered correctly. While this is not a new task in itself, the challenge focuses on employing textual entailment technologies as the backbone of this educational application. As a consequence, we formalize the question “Did the student answer correctly?” as “Can the reference answer be inferred from the student’s answer?”.
