  abstract  = {Full text discourse parsing relies on texts comprehensively annotated with
	discourse relations. 
	To this end, we address a significant gap in the inter-sentential discourse
	relations annotated in the Penn Discourse Treebank (PDTB), namely the class of
	cross-paragraph implicit relations, which account for 30% of inter-sentential
	relations in the corpus. We present our annotation study to explore the
	incidence rate of adjacent vs. non-adjacent implicit relations in
	cross-paragraph contexts, and the relative degree of difficulty in annotating
	them. Our experiments show a high incidence of non-adjacent relations that are
	difficult to annotate reliably, suggesting the practicality of backing off from
	their annotation to reduce noise for corpus-based studies. Our resulting
	guidelines follow the PDTB adjacency constraint for implicits while employing
	an underspecified representation of non-adjacent implicits, and yield 62%
	inter-annotator agreement on this task.},
