Evaluation of a Predictive Algorithm for Converting Linear Strings to Mathematical Formulae for an Input Method

Recently, some computer-aided assessment (CAA) systems are able to assess learner’s answers using mathematical expressions. However, the standard input method for mathematics is cumbersome for novice learners. In 2011, the last author Fukui proposed a new mathematical input method similar to the ones used for inputting Japanese characters in many systems. This method allows users to input mathematical expressions using colloquial-style mathematical string. However, users must convert each element contained in the colloquial-style mathematical string. In this study, we propose a predictive algorithm for converting the whole mathematical formulae.
