  abstract  = {Sub-character components of Chinese characters carry important semantic
	information, and recent studies have shown that utilizing this information can
	improve performance on core semantic tasks. In this paper, we hypothesize that
	in addition to semantic information, sub-character components may also carry
	emotional information, and that utilizing it should improve performance on
	sentiment analysis tasks. We conduct a series of experiments on four Chinese
	sentiment data sets and show that we can significantly improve the performance
	in various tasks over that of a character-level embeddings baseline. We then
	focus on qualitatively assessing multiple examples and trying to explain how
	the sub-character components affect the results in each case.},
