In this paper, we give the overview of the open domain Question Answering (or open domain QA) shared task in NLPCC 2015. We first review the background of QA, and then describe open domain QA shared task in this year’s NLPCC, including the construction of the benchmark datasets, the auxiliary dataset, and the evaluation metrics. The evaluation results of submissions from participating teams are presented in the experimental part, together with a brief introduction to the techniques used in each participating team’s QA system.
