Development of IR Tool for Tree-Structured Math ML-based Mathematical Descriptions

Abstract

The quantity of Web contents including math has been skyrocketing in recent years, such as Wikipedia articles and BBS focusing on math. Some pieces of previous research have dealt with the development of IR systems targeting MathML-based math expressions. They are, however, still developing in terms of lack of fuzzy search functions or low hit rates. One of the authors in ICCE2008 proposed the IR tool enjoying a fuzzy search function, by adopting regular expressions used in MySQL. In this study, it is our objective to additionally propose a “tree structure” algorithm for the fuzzy search function with better precisions.
