The International Joint Conference on Artificial Intelligence (or IJCAI) is a premier international gathering of Artificial Intelligence (AI) researchers and practitioners. It is organized by the IJCAI, Inc., and has been held biennially in odd-numbered years since 1969. It is sponsored jointly by International Joint Conferences on Artificial Intelligence (IJCAI) Organization, and the national AI societie(s) of the host nation(s). IJCAI is a highly selective conference. For instance, only 17% of the papers submitted to the conference were accepted in 2011. This makes it a more selective publication than many AI journals.Three research awards are given at each IJCAI conference.
