We describe a framework using the BERT-based query modification technique for the NTCIR-16 Data Search 2 IR Subtask. In our framework, we took a 3-step procedure: (1) the query modification, (2) item filtering by BM25, and (3) item re-ranking by BERT. The experimental results showed that our framework using the query modification did not outperform the baseline method that does not use the query modification.conference pape
