论文摘要
我们提出了一个系统，该系统允许用户使用依赖性图上的句法模式搜索大型语言注释的语料库。与以前的尝试相反，我们引入了一种轻巧的查询语言，该语言不需要用户知道基础句法表示的详细信息，而是通过提供一个示例句子和简单的标记来查询语料库。搜索是由于有效的语言图形指数和检索引擎而以交互速度执行的。这允许对基于语法的查询进行快速探索，开发和完善。我们使用两个语料库的查询演示了该系统：英文Wikipedia和一系列英语PubMed摘要。 Wikipedia系统的演示可在以下网址提供：https：//allenai.github.io/spike
We present a system that allows a user to search a large linguistically annotated corpus using syntactic patterns over dependency graphs. In contrast to previous attempts to this effect, we introduce a light-weight query language that does not require the user to know the details of the underlying syntactic 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 an efficient linguistic graph-indexing and retrieval engine. This allows for rapid exploration, development and refinement of syntax-based queries. We demonstrate the system using queries over two corpora: the English wikipedia, and a collection of English pubmed abstracts. A demo of the wikipedia system is available at: https://allenai.github.io/spike
