In this paper, we describe a method for as- sessing student answers, modeled as a para- phrase identification problem, based on sub- stitution by Basic English variants. Basic En- glish paraphrases are acquired from the Sim- ple English Wiktionary. Substitutions are ap- plied both on reference answers and student answers in order to reduce the diversity of their vocabulary and map them to a common vocabulary. The evaluation of our approach on the SemEval 2013 Joint Student Response Analysis and 8th Recognizing Textual Entail- ment Challenge data shows promising results, and this work is a first step toward an open- domain system able to exhibit deep text un- derstanding capabilities.
