This paper details our participation in the TREC 2019 Deep Learning Track task including Passage Ranking task. In the Top-1000 Re-ranking subtask of Passage Ranking task, we performed passage ranking based on the technique of Conv-KNRM and BERT. In order to get a better ranking result, we divided the task into two stages. In the first stage we use Conv-KNRM model for initial ranking, then in the second stage we combine the results with a state-of-the-art BERT re-ranker.
