Development of a Learners’ Dictionary of Polysemous Japanese Words and Some Proposals for Learners’ Lexicography

The dictionary series Nihongo tagigo gakushū jiten (“A Learner’s Dictionary of Multi-sense Japanese Words”) proposes a new approach to learners’ dictionaries, based on cognitive linguistics theory and on a corpus-based approach.
