OpenEphyra is the first open source question answering (QA) system. It retrieves answers to natural language questions from the Web and other sources - just type in your questions and get back answers. OpenEphyra comes with implementations of algorithms that proved effective in Carnegie Mellon's Ephyra system, which participated in the TREC evaluations. It is platform independent and can be set up in just a few minutes.
The goal of this project is to give researchers the opportunity to develop new QA techniques without worrying about the end-to-end system. OpenEphyra also facilitates evaluations and comparisons of different approaches by providing a common platform for experiments. In addition, OpenEphyra can be used for educational purposes, such as for computer science course projects.
