Abstract: In event anaphora resolution, the antecedent of the anaphor is an event and the anaphor is a noun phrase.They are parts of different semantic categorization systems. So most of features applied in entity anaphora resolution are not appropriate for event anaphora resolution. hhis paper proposed an event anaphora resolution framework using a machine learning approach. The instances creation and the features selection were presented in detail. This paper also illustrated the experiment results on OntoNotes 3. 0 corpus. From the results we can find that the recall of the framework is very good, but the precision must be improved in the further work.

Key words: Event anaphora resolution, Machine learning approach, Instances creation, Features selection
