This paper describes our system for the ChEMU 2021 task 2 of anaphora resolution for extracting chemical reactions from patents. We divide the task into two subtasks: (1) span detection of mentions that include antecedent and anaphor; and (2) mention classification and relation detection. For the first task, we use a deep learning-based approach. For the second task, we use a rule-based approach that uses features related to chemical reactions by ChemicalTagger, which is a state-of-the-art text-mining tool for chemistry. Our system obtained an exact-match F-score of 0.6907 and a relaxed match F-score of 0.7459.
