sentence1: amr parsing is a new research problem , with only a few papers published to date ( flanigan et al. , 2014 ; wang et al. , 2015 ) and a publicly available corpus of more than 10,000 english/amr pairs .
sentence2: amr parsing is the task of taking a sentence as input and producing as output an abstract meaning representation ( amr ) that is a rooted , directed , edge-labeled and leaf-labeled graph that is used to represent the meaning of a sentence ( banarescu et al. , 2013 ) .
