OpenRefine - Powerful tool for working with messy data

Ephyra is a modular and extensible framework for open domain question answering (QA). The system retrieves accurate answers to natural language questions from the Web and other sources. The goal is to give researchers the opportunity to develop new QA techniques without worrying about the end-to-end system.
