Table 5: Preference weight assignment for pronominal anaphora

Pref. No.	Description	Weight
1	Antecedents that are in the same AP as the anaphor	35
2	Antecedents that are in the previous AP to that containing the anaphor	20
2a	Antecedents that are in the most recent unclosed AP	30
2b	Antecedents in the topic	15
6	Antecedents that appear with the verb of the anaphor more than once	5
7	Antecedents that are in the same position with reference to the verb as the anaphor (before or after)	5
8	Antecedents that are in the same position with reference  to the utterance as the anaphor	5
12	The nearest antecedent to the anaphor	YES

In this final experiment, the preference set obtained in the previous experiment was used (including the minimum set of preferences that we considered to be the optimal configuration). Then, several alternatives were used in order to obtain an optimal preference weight assignment. Tables 5 and 6 show the preference weight assignments for pronominal and adjectival anaphora, respectively.
 

Table 6: Preference weight assignment for adjectival anaphora

Pref. No.	Description	Weight
1	Antecedents that are in the same AP as the anaphor	35
2	Antecedents that are in the previous AP to that containing the anaphor	10
2a	Antecedents that are in the most recent unclosed AP	10
2b	Antecedents in the topic	35
3	Antecedents that share the same kind of modifiers	5
4	Antecedents with exactly the same modifiers	5
5	Antecedents that agree in number	5
8	The nearest antecedent to the anaphor	YES

This final set of constraints and preferences was presented in Section 5.2.
