The Open Advancement of Question Answering (OAQA) project (2007-present) works to provide foundational architecture and methodology for agile collaborative research in automatic question answering. By making long-term commitments to an architecture that supports best-practices research methodology, OAQA is accelerating the advancement of QA technologies in several application areas. The OAQA approach combines an object-oriented software architecture with comprehensive metrics, measurement and error analysis, at the system and module levels, and has been applied to a variety of challenge problems (see below for notable examples).
The LiveQA Challenge. Beginning in 2015, CMU has collaborated with Yahoo! Labs (as part of the InMind project) to develop automatic answering agents that can respond to real-time questions from web users (like those received by the Yahoo! Answers community QA web site). CMU student Di Wang created a LiveQA system which combined standard retrieval algorithms (BM25) with state-of-the-art deep learning models  to achieve the highest score among all participants in the 2015 TREC LiveQA Challenge . In 2016, Di extended his system to include a novel answer ranking method based on attentional encoder-decoder recurrent neural networks  and achieved the highest score among 25 automatic systems that were evaluated in the 2016 LiveQA Track .

The BioASQ Challenge. From 2012 to 2016, a team led by LTI Ph.D. student Zi Yang collaborated with Hoffman-LaRoche's Innovation Center to develop information systems for unstructured biomedical text, including a passage retrieval system for the TREC Genomics dataset , a decision support system for gene targeting which leverages information gathered from PubMed articles by an automatic QA system , a Biomedical Semantic QA system which received six 1st-place scores in the 2015 BioASQ Challenge tasks, which included snippet retrieval, concept retrieval, and exact answer retrieval , and a Biomedical Semantic QA system which received three 1st-place scores in exact answer retrieval in the 2016 BioASQ Challenge .

The Jeopardy! Challenge. From 2007 to 2011, CMU collaborated with the IBM DeepQA Group to develop an open-source framework for OAQA . The initial OAQA architecture and data model were used to build systems for the TREC challenge problem and the Jeopardy! challenge problem [2,3,4]. Carnegie Mellon students Nico Schlaefer and Hideki Shima also contributed algorithms and code to IBM's Watson system, as participants in IBM's summer internship program.
