  abstract  = {The research question we explore in this study is how to obtain syntactically
	plausible word representations without using human annotations.
	Our underlying hypothesis is that word ordering tests, or linearizations, is
	suitable for learning syntactic knowledge about words.
	To verify this hypothesis, we develop a differentiable model called Word
	Ordering Network (WON) that explicitly learns to recover correct word order
	while implicitly acquiring word embeddings representing syntactic knowledge.
	We evaluate the word embeddings produced by the proposed method on downstream
	syntax-related tasks such as part-of-speech tagging and dependency parsing.
	The experimental results demonstrate that the WON consistently outperforms both
	order-insensitive and order-sensitive baselines on these tasks.},
