摘要:

我们提出了一个系统,允许生命科学研究人员搜索语言注释语料库的科学文本使用模式依赖图,以及使用模式令牌序列和布尔关键字查询的一个强大的变种。与以前的尝试依赖性为基础的搜索,我们引入了一个轻量级的查询语言,不需要用户知道的细节的基础语言表示,而是查询语料库提供一个简单的标记加上例句。由于高效的语言图索引和检索引擎,搜索以交互式速度进行。这允许用户查询的快速探索、开发和细化。我们使用两个语料库的示例工作流演示了该系统:PubMed语料库,包括14,446,243 PubMed摘要和CORD-19数据集,收集了超过45,000篇关于COVID-19研究的研究论文。该系统可在https://allenai.github.io/spike上公开获取

英文摘要:

We present a system that allows life-science researchers to search a linguistically annotated corpus of scientific texts using patterns over dependency graphs, as well as using patterns over token sequences and a powerful variant of boolean keyword queries. In contrast to previous attempts to dependency-based search, we introduce a light-weight query language that does not require the user to know the details of the underlying linguistic representations, and instead to query the corpus by providing an example sentence coupled with simple markup. Search is performed at an interactive speed due to efficient linguistic graph-indexing and retrieval engine. This allows for rapid exploration, development and refinement of user queries. We demonstrate the system using example workflows over two corpora: the PubMed corpus including 14,446,243 PubMed abstracts and the CORD-19 dataset, a collection of over 45,000 research papers focused on COVID-19 research. The system is publicly available at https://allenai.github.io/spike
