PositionRank: An Unsupervised Approach to Keyphrase Extraction from Scholarly Documents

The large and growing amounts of online scholarly data present both challenges and opportunities to enhance knowledge discovery. One such challenge is to automatically extract a small set of keyphrases from a document that can accurately describe the document's content and can facilitate fast information processing.
