  abstract  = {Linguistic typology provides features that have a potential of uncovering deep
	phylogenetic relations among the world's languages.
	One of the key challenges in using typological features for phylogenetic
	inference is that horizontal (spatial) transmission obscures vertical
	(phylogenetic) signals.
	In this paper, we characterize typological features with respect to the
	relative strength of vertical and horizontal transmission.
	To do this, we first construct (1) a spatial neighbor graph of languages and
	(2) a phylogenetic neighbor graph by collapsing known language families.
	We then develop an autologistic model that predicts a feature's distribution
	from these two graphs.
	In the experiments, we managed to separate vertically and/or horizontally
	stable features from unstable ones, and the results are largely consistent with
	previous findings.},
