Application of Reading Data in an Integrated Learner Corpus

This study describes a learner corpus that includes linguistic data produced by learners of English as a foreign language (EFL learners) with respect to pronunciation, writing, listening, and reading. Among these four types of linguistic data, reading data were used in the development of a formula for predicting the readability of sentences for EFL learners. The experimental results demonstrated that the developed readability formula was approximately 65% effective in predicting readability assessments by EFL learners.
