Abstract
This paper reports an attempt to introduce a computerized system which makes it possible to select important English words in an efficient way. Vocabulary building is indisputably important in developing English skills, so we have adopted a web-based English vocabulary learning system that we use in conjunction with regular classes. To maintain this system, it is necessary to select target vocabulary words from textbooks while also referring to several wordbooks. Although this process serves an important purpose, it takes a certain amount of time each time, which inevitably constitutes a problem. As a means of addressing this issue, we have developed a computerized system for selecting important English words based on the data of multiple wordbooks. This new system has made it possible to reduce the time it takes to choose target words.
