Furthermore, by corresponding with other researchers, we have learned that previous papers on AMR parsing report SMATCH scores using differing values of r. Another problem is that SMATCH maps one node to another regardless of their actual content, and it only considers edge labels when comparing two edges.
two different edges, such as "ask-01 :ARG1 leave-11" and "make-01 :ARG1 pie" in Figure 1, can be considered identical by SMATCH.
