Towards generating multiple-choice tests for supporting extensive reading

We propose a method for generating multiplechoice test for an English text selected by a learner and its answer, that are used to make a self-assessment whether the learner comprehends the text after reading it. In our method, the system extracts several important sentences from the text, and replaces one word in each of these sentences with its synonym (if possible). One of these sentences is then selected as a correct optional sentence, while further changes to the polarities or nouns in the remaining sentences are carried out to generate distractor optional sentences for the multiplechoice test. Our method has potential to make extensive reading in English more effective.
