Centering in-the-large: Computing referential discourse segments
<|reference_start|>Centering in-the-large: Computing referential discourse segments: We specify an algorithm that builds up a hierarchy of referential discourse segments from local centering data. The spatial extension and nesting of these discourse segments constrain the reachability of potential antecedents of an anaphoric expression beyond the local level of adjacent center pairs. Thus, the centering model is scaled up to the level of the global referential structure of discourse. An empirical evaluation of the algorithm is supplied.<|reference_end|>
