Our system consists of three subsystems: (1) the Workspace Coreference System (WCS) incrementally clusters mentions using semantic similarity based on embeddings combined with lexical feature heuristics; (2) the Mention-to-Mention (M2M) coreference resolution system pairs same entity mentions; (3) the Discourse Deixis Resolution (DDR) system employs a Siamese Network to detect discourse anaphor-antecedent pairs. WCS achieved F1-score of 55.6% averaged across the evaluation test sets, M2M achieved 57.2% and DDR achieved 21.5%. %R 10.18653/v1/2021.codi-sharedtask.3 %U https://aclanthology.org/2021.codi-sharedtask.3 %U https://doi.org/10.18653/v1/2021.codi-sharedtask.3 %P 32-42
