EFLLex: A Graded Lexical Resource for Learners of English as a Foreign Language

This paper introduces EFLLex, an innovative lexical resource that describes the use of 15,280 English words in pedagogical materials across the proficiency levels of the European Framework of Reference for Languages. The methodology adopted to produce the resource implies the selection of an efficient part-of-speech tagger, the use of a robust estimator for frequency computation and some manual post-editing work. The content of the resource is described and compared to other vocabulary lists (MRC and BNC) and to a reference pedagogical resource: the English Vocabulary Profile.
