The Right Frontier Constraint (RFC), as a constraint on the attachment of new con- stituents to an existing discourse struc- ture, has important implications for the in- terpretation of anaphoric elements in dis- course and for Machine Learning (ML)ap- proaches to learning discourse structures. In this paper we provide strong empirical support for SDRT’s version of RFC.The analysis of about 100 doubly annotated documents by five different naive annota- tors shows that SDRT’s RFC is respected about 95% of the time. The qualitative analysis of presumed violations that we have performed shows that they are either click-errors or structural misconceptions.
