| Research Abstract |
The present research is aimed at improving the overall quality and usefulness of a Web-based reading support system originally developed for learners world-wide who are studying Japanese as a foreign language(JFL). In order to improve the present system, attention was focused on determining the benchmark for levels of difficulty in terms of vocabulary difficulty and sentence complexity. JFL learners from a wide variety of language backgrounds were surveyed to determine which vocabulary items and grammatical structures pose comprehension difficulty for learners at different levels of proficiency. It was found that by taking both word difficulty and sentence complexity into account, a more well-rounded(comprehensive) determination of the overall level of difficulty could be made. Furthermore, techniques of data mining were used to determine trends in usage of the on-line Tutor dictionary. This kind of data is necessary for making adjustments in the information covered in the dictionary and for providing insights into how real learners use the dictionary. The results of this research will be incorporated into the on-line reading support system and made available to educators and learners throughout the world.
