| Abstract: |
Word frequency information has been an indispensable part of electronic dictionaries for learners of English. A review of the current five major electronic learner's dictionaries (LDOCE5, OALD7, CALD3, MED2, COBUILD5) shows that word frequency information is mainly based on raw frequency without considering distributed frequency across different genres. Our research explores the distributed frequency in 14 reorganized genres (9 written, 5 spoken) of the British National Corpus XML Edition (BNC XML 2007). Statistics show that a core vocabulary for EFL learners selcted by distributed frequency achieves higher cumulative coverage than a core vocabulary selected by raw frequency alone. An electronic "English Frequency Dictionary" has been developed to display distributed frequency across genres as a histogram. This software helps EFL learners to understand the register and cultural implication of English words, and to identify some subtle distinctions between synonyms. This enhancement is proposed for future electronic learner's dictionaries. |
