OpenEphyra- 开源问答系统

OpenEphyra 是一个使用 Java 开发的模块化、可扩展的问答系统、安装简单。

It retrieves answers to natural language questions from the Web and other
sources. OpenEphyra comes with implementations of algorithms that proved
effective in Carnegie Mellon’s Ephyra system, which participated in the TREC
evaluations.The goal of this project is to give researchers the opportunity to
develop new QA techniques without worrying about the end-to-end system.
