LG AI Research participated in two tasks (1a and 1b) of the ChEMU 2022 challenge for extracting chemical reaction information from patents, achieving the highest performance among four teams. They used a domain-specific language model post-trained on chemical and biomedical texts, and developed separate NER and RE models operating in a pipeline.
