Research Abstract

Digital libraries which store academic papers require some techniques for automatic extraction of bibliographic and other information from the papers. This study proposed a method of automatically extracting bibliographic information from OCRed document images of title pages of academic papers and from reference strings listed at the end of papers by using a conditional random field (CRF). This study also proposed a recommendation service of related papers using the technical terms extracted from academic papers and investigated ways to support online-browsing of academic papers using tablet PCs.
