  abstract  = {In this paper, we discuss our ongoing efforts to construct a scientific paper
	browsing system that helps users to read and understand advanced technical
	content distributed in PDF. Since PDF is a format specifically designed for
	printing, layout and logical structures of documents are indistinguishably
	embedded in the file. It requires much effort to extract natural language text
	from PDF files, and reversely, display semantic annotations produced by NLP
	tools on the original page layout. In our browsing system, we tackle these
	issues caused by the gap between printable document and plain text. Our system
	provides ways to extract natural language sentences from PDF files together
	with their logical structures, and also to map arbitrary textual spans to their
	corresponding regions on page images. We setup a demonstration system using
	papers published in ACL anthology and demonstrate the enhanced search and
	refined recommendation functions which we plan to make widely available to NLP
	researchers.},
