Information-Retrieval Tool for Math Expressions as Infrastructure of Training Engineers via E-Learning

In this study, it's our objective to develop an information-retrieval tool for mathematical expressions to enhance usability of contents including math. The authors believe such infrastructure is essential for training engineers via e-Learning, especially in the field of control engineering where learners are required to manipulate equations and functions. Our target is math expressions written by Presentation MathML (Mathematical Markup Language), which was developed for describing math on the web. The results of pilot experiments are also shown.
