  abstract  = {In this paper, we propose utilising eye gaze information for
	  estimating parameters of a Japanese predicate argument structure
	  (PAS) analysis model.  We employ not only linguistic information in
	  the text, but also the information of annotator eye gaze during
	  their annotation process.  We hypothesise that annotator's frequent
	  looks at certain candidates imply their plausibility of being the
	  argument of the predicate. Based on this hypothesis, we consider
	  annotator eye gaze for estimating the model parameters of the PAS
	  analysis. The evaluation experiment showed that introducing eye gaze
	  information increased the accuracy of the PAS analysis by 0.05
	  compared with the conventional methods.},
