摘要:

我们提出了一个系统,允许用户搜索一个大型的语言注释语料库使用依赖图的句法模式。在以前的尝试,这种效果相反,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,底层的句法表示,而是查询语料库提供一个简单的标记加上一个例子。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。这允许快速探索、开发和改进基于语法的查询。我们演示了系统使用查询两个语料库:英语维基百科,和英语pubmed摘要的集合。wikipedia系统的演示可在以下网址获得:https://allenai.github.io/spike

英文摘要:

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
