摘要
文档扳手的信息提取框架是由Fagin, Kimelfeld, Reiss和Vansummeren (PODS 2013, J. ACM 2015)作为IBM信息提取引擎SystemT中使用的查询语言AQL的形式化引入的。自2013年以来，这个框架已经被数据库管理社区的原则和其他人深入研究。本文简要概述了有关文档生成器的概念、结果和最新发展。
Document Spanners - A Brief Overview of Concepts, Results, and Recent Developments
The information extraction framework of document spanners was introduced by Fagin, Kimelfeld, Reiss, and Vansummeren (PODS 2013, J. ACM 2015) as a formalisation of the query language AQL, which is used in IBM's information extraction engine SystemT. Since 2013, this framework has been investigated in depth by the principles of database management community and beyond. The present paper gives a brief overview of concepts, results, and recent developments concerning document spanners.
