  Program comprehension is a dominant process in software development and
maintenance. Experts are considered to comprehend the source code efficiently
by directing their gaze, or attention, to important components in it. However,
reflecting the importance of components is still a remaining issue in gaze
behavior analysis for source code comprehension. Here we show a conceptual
framework to compare the quantified importance of source code components with
the gaze behavior of programmers. We use "attention" in attention models (e.g.,
code2vec) as the importance indices for source code components and evaluate
programmers' gaze locations based on the quantified importance. In this report,
we introduce the idea of our gaze behavior analysis using the attention map,
and the results of a preliminary experiment.
