  abstract  = {In this paper we present  on-going work on annotating negation in Spanish
	clinical documents. A corpus of anamnesis and radiology reports has been
	annotated by two domain expert annotators with negation markers and negated
	events. The Dice coefficient for inter-annotator agreement is higher than 0.94
	for negation markers and higher than 0.72 for negated events. The corpus will
	be publicly released when the annotation process is finished, constituting the
	first corpus annotated with negation for Spanish clinical reports available for
	the NLP community.},
