With the proposed scheme, we can annotate only those pronoun which are required in the referent span as shown below : <fs name='NP6' ref='NP2' refmod='NP1' > If in some case, both the modifiers are required for the interpretation of the pronoun than both the modifiers can be included in 'refmod' attribute as follows : In view of the computational efficiency, as discussed in section 4.1(Sequential annotation), we adopt chain marking for anaphora annotation in this scheme.
if an entity is referred by more than one pronouns or has repeated mentions in a discourse, then for each pronoun, we annotate the last mention of the corresponding referent-entity as the antecedent.
