摘要:

本文介绍了我们提交的2021年健康社交媒体挖掘(SMM 4 H)共享任务。我们参与了两项任务:(1)对英文推文中提及的药物不良反应(ADE)进行分类、提取和标准化(任务1);(2)对包含症状的COVID-19推文进行分类(任务6)。我们的第一个任务的方法使用的语言表示模型RoBERTa与二进制分类头。对于第二个任务,我们使用基于RoBERTa的BERTweet。对这两个任务的预训练模型进行微调。模型被放置在定制的特定于域的处理管道之上。我们的系统在子任务1(a)的所有提交中排名第一,F1分数为61%。对于子任务1(b),我们的系统获得了50%的F1分数,比所有提交的平均分数提高了+8%F1。BERTweet模型在SMM 4 H 2021 Task-6上取得94%的F1分数。

英文摘要:

This paper describes our submissions for the Social Media Mining for Health (SMM4H)2021 shared tasks. We participated in 2 tasks:(1) Classification, extraction and normalization of adverse drug effect (ADE) mentions in English tweets (Task-1) and (2) Classification of COVID-19 tweets containing symptoms(Task-6). Our approach for the first task uses the language representation model RoBERTa with a binary classification head. For the second task, we use BERTweet, based on RoBERTa. Fine-tuning is performed on the pre-trained models for both tasks. The models are placed on top of a custom domain-specific processing pipeline. Our system ranked first among all the submissions for subtask-1(a) with an F1-score of 61%. For subtask-1(b), our system obtained an F1-score of 50% with improvements up to +8% F1 over the score averaged across all submissions. The BERTweet model achieved an F1 score of 94% on SMM4H 2021 Task-6.
