Abstract
在這項研究中,探索了各種最先進的生物醫學預訓練 BERT 模型用於兩個BioCreative VII 競賽,分別為NLM-CHEM Track和LitCovid Track,並提出了一種基於 BERT 的集成學習方法來整合各種模型的優勢以提高系統的性能。NLM-CHEM任務的實驗結果表明,我提出的方法可以在嚴格和近似評估方法上分別以 85% 和 91.8% 的 F1 分數實現顯著的性能。 此外,所提出的MeSH ID 歸一化算法在實體歸一化方面是有效的,在嚴格和近似評估方法上都可以達到 80% 左右的 F1-score。 對於 LitCovid任務,所提出的方法在檢測 COVID-19 文獻中的主題方面也很有效,可以優於其他隊伍並在 LitCovid 語料庫上實現最先進的性能。
