Claims are a fundamental unit of scientific discourse. The exponential growth in the number of scientific publications makes automatic claim extraction an important problem for researchers who are overwhelmed by this information overload. Such an automated claim extraction system is useful for both manual and programmatic exploration of scientific knowledge. In this paper, we introduce an online claim extraction system and a dataset of 1,500 scientific abstracts from the biomedical domain with expert annotations for each sentence indicating whether the sentence presents a scientific claim. We compare our proposed model with several baseline models including rule-based and deep learning techniques. Our transfer learning approach with a fine-tuning step allows us to bootstrap from a large discourse-annotated dataset (Pubmed-RCT) and obtains F1-score over 0.78 for claim detection while using a small annotated dataset of 750 papers. We show that using this pre-trained model based on the discourse prediction task improves F1-score by over 14 percent absolute points compared to a baseline model without discourse structure. We release a publicly accessible tool for discourse model, claim detection model, along with an annotation tool. We discuss further applications beyond Biomedical literature.

本文介绍了一种用于从生物医学领域的科学文章摘要中提取科学主张的模型，该模型使用传递学习技术进行微调，并将其与基于规则和深度学习技术的几个基准模型进行比较。最终模型使用微调后的传递学习技术与基准模型相比，其F1得分提高了14个百分点。同时，作者还提供了一个公共工具用于进行论述和主张的预测以及注释工具，并探讨了其在生物医学文献以外的其他应用。
