A lightweight, human-in-the-loop evaluation scheme for machine translation (MT) systems is proposed. It extrinsically evaluates MT systems using human subjects' scores on second language ability test problems that are machine-translated to the subjects' native language. A large-scale experiment involving 320 subjects revealed that the context-unawareness of(More)
In this paper, we analyzed Japanese schools of medicine to assess the effects of learning environment and devised teaching methods. In addition, we assessed the mechanism of school factors and educational outcome. From the results of multiple logistic regression analysis, we confirmed that learning environment didn't affect educational outcome and devised(More)

It has been shown that there is a significant relationship between children's mentalizing skills and creation of an imaginary companion (IC). Theorists have proposed that interaction with an IC may improve mentalizing skills, but it is also possible that children's mentalizing skills affect their creation of an IC. In this longitudinal study, we examined(More)
We used an item response theory (IRT) model to simultaneously compare the psychometric properties of 3 commonly used self-report depression scales translated into Japanese-the Zung Self-Rating Depression Scale (SDS), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Patient Health Questionnaire Depression Scale (PHQ-9)-in a Japanese(More)
This paper reports on an experiment where 795 human participants answered to the questions taken from second language proficiency tests that were translated to their native language. The output of three machine translation systems and two different human translations were used as the test material. We classified the translation errors in the questions(More)
In this paper, in order to assess the effect of perceived autonomy on student engagement and academic performance in Japanese university students, we conducted two studies. In Study I, we created the Japanese student engagement scale. We then conducted surveys using this scale and, based on the resulting data, confirmed that the items in the scale(More)
