Following Ruch et al. ( 2003 ) and Barzilay and Lee ( 2004 ) , we employed Hidden Markov Models to model the discourse structure of MEDLINE abstracts . The four states in our HMMs correspond to the information that characterizes each section ( `` introduction '' , `` methods '' , `` results '' , and `` conclusions '' ) and state transitions capture the discourse flow from section to section .
