领域无关的科学概念抽取

Domain-independent Extraction of Scientific Concepts from Research Articles

Arthur Brack, Jennifer D'Souza, Anett Hoppe, Sören Auer, Ralph Ewerth

摘要:

我们研究了从学术文章摘要中提取独立于领域的科学概念的新任务,并提出了两个贡献。首先,我们提出了一套通用的科学概念,已确定在一个系统的注释过程。这套概念是用来注释语料库的科学摘要从10个领域的科学,技术和医学在短语的水平,在与领域专家的共同努力。所得到的数据集用于一组基准实验中,以(a)为该任务提供基线性能,(b)检查域之间概念的可转移性。其次,我们提出两个深度学习系统作为基线。特别是,我们提出了主动学习,以处理不同的领域在我们的任务。实验结果表明:(1)非专家在与领域专家协商后,可以获得基本一致的结果;(2)基线系统获得了相当高的F1分数;(3)主动学习使我们能够将所需的训练数据量减少近一半。

英文摘要:

We examine the novel task of domain-independent scientific concept extraction from abstracts of scholarly articles and present two contributions. First, we suggest a set of generic scientific concepts that have been identified in a systematic annotation process. This set of concepts is utilised to annotate a corpus of scientific abstracts from 10 domains of Science, Technology and Medicine at the phrasal level in a joint effort with domain experts. The resulting dataset is used in a set of benchmark experiments to (a) provide baseline performance for this task, (b) examine the transferability of concepts between domains. Second, we present two deep learning systems as baselines. In particular, we propose active learning to deal with different domains in our task. The experimental results show that (1) a substantial agreement is achievable by non-experts after consultation with domain experts, (2) the baseline system achieves a fairly high F1 score, (3) active learning enables us to nearly halve the amount of required training data.
