Автоматическое создание упражнений из текстов на японском языке
This article presents an approach to the automatic generation of open cloze exercises based on arbitrary English text. The exercise format is similar to the open cloze test used in Cambridge English certificate exams (FCE, CAE, CPE). The presented method also makes it possible to adjust the difficulty of the resulting exercises to better suit specific proficiency levels. Three experiments were conducted to evaluate the usefulness of the machine-generated exercises, compare them with authentic Cambridge English tests and study the difficulty-setting capabilities. The experiments showed that the generation method used was quite effective. With some customization, the method can be applied to generating similar exercises for other languages.
Current trends in education, namely blended learning and computer-assisted language learning, underlie the growing interest to the task of automatically generating language exercises. Such automatic systems are especially in demand given the variability in language learning. Despite the abundance of resources for language learning, there is often a lack of specific exercises targeting a particular group of learners or ESP course. This paper gives an overview of a computer system called Exercise Maker that is aimed at flexible and versatile language exercise generation. The system supports seven exercise types, which can be generated from arbitrary passages written in English. Being able to tailor educational material to learners’ interests is known to boost motivation in learners (Heilman et al., 2010). An important feature of the system is the automatic ranking of the source passages according to their complexity/readability. As shown by expert evaluation, the automatically generated exercises are of high quality: the gap precision is about 97-98%, while the overall exercise acceptance rate varies from 90% to 97.5%. Exercise Maker is freely available for educational and research purposes.
