The subtypes of abstract entity anaphora are characterised as follows: abstrProp describes anaphoric relations with an antecedent of propositional type, abstEvType describes anaphoric relations with an event type antecedent, and abstrCluster describes anaphoric relations where the anaphor refers to a cluster of propositions. For nominal antecedents, we annotate eight secondary relation types: The relation ident is chosen for pronominal anaphors or anaphor-antecedent pairs with identical head noun. The value propName is chosen if the anaphoric element is a proper name that refers to an NP antecedent.
