Abstract:**
We found a way to use mathematical search
to provide better navigation for reading papers on computers. Since the
superficial information of mathematical expressions is ambiguous, considering
not only mathematical expressions but also the texts around them is necessary.
We present how to extract a natural language description, such as variable names
or function definitions that refer to mathematical expressions with various
experimental results. We first define an extraction task and constructed a
reference dataset of 100 Japanese scientific papers by hand. We then propose the
use of two methods, pattern matching and machine learning based ones for the
extraction task. The effectiveness of the proposed methods is shown through
experiments by using the reference set.
