Certain schemes have been aimed at abstracts , e.g. , ( McKnight & Srinivasan , 2003 ; Ruch et al , 2007 ; Hirohata et al , 2008 ; Bj ? rne et al , 2009 ) . The work of Hirohata et al ( 2009 ) has been integrated with the MEDIE service5 ( Miyao et al , 2006 ) , allowing the user to query facts using conclusions , results , etc . For full papers , the most notable work has focussed on argumentative zoning ( AZ ) ( Teufel et al , 1999 ; Teufel & Moens , 2002 ; Teufel et al , 2009 ; Teufel , 2010 ) . An important aspect of AZ involves capturing the attribution of knowledge claims and citation function , and the scheme has been tested on information extraction and summarisation tasks with Computational Linguistics papers .
