Abstract

This paper reports on the process of modifying the ModelCreator item generation system to produce output in multiple languages. In particular, Japanese and Spanish are now supported in addition to English. The addition of multilingual functionality was considerably facilitated by the general formulation of our natural language generation system, which proceeds in three stages, whereby the first two stages are largely language-independent. This multilingual capability is very promising for the domain of educational assessment because, when combined with item modeling, it provides the potential to produce a large pool of automatically constructed items, with difficulty estimates and balanced forms for speakers of different languages.
