摘要:

科技文本的信息抽取可以引导读者获取科技文献的核心信息。但是,狭义的IE系统只能提取所捕获信息的一小部分,而开放的IE系统在科学文本中遇到的长而复杂的句子上表现不佳。在这项工作中,我们结合这两种类型的系统的输出,实现半开放的关系抽取,一个新的任务,我们在生物学领域探索。首先,我们提出了聚焦开放生物信息抽取(FOBIE)数据集,并使用FOBIE训练一个国家的最先进的狭窄的科学IE系统,以提取权衡关系和论点,是中央生物学文本。然后,我们运行两个狭窄的IE系统和一个国家的最先进的开放IE系统上的语料库的10K开放获取的科学生物学文本。我们发现,大量(65%)的错误和无信息的开放IE提取可以使用窄IE提取过滤。此外,我们发现,保留提取显着更经常为读者提供信息。

英文摘要:

Information Extraction (IE) from scientific texts can be used to guide readers to the central information in scientific documents. But narrow IE systems extract only a fraction of the information captured, and Open IE systems do not perform well on the long and complex sentences encountered in scientific texts. In this work we combine the output of both types of systems to achieve Semi-Open Relation Extraction, a new task that we explore in the Biology domain. First, we present the Focused Open Biological Information Extraction (FOBIE) dataset and use FOBIE to train a state-of-the-art narrow scientific IE system to extract trade-off relations and arguments that are central to biology texts. We then run both the narrow IE system and a state-of-the-art Open IE system on a corpus of 10k open-access scientific biological texts. We show that a significant amount (65%) of erroneous and uninformative Open IE extractions can be filtered using narrow IE extractions. Furthermore, we show that the retained extractions are significantly more often informative to a reader.
