Omuokdlb at the NTCIR-17 QA Lab-Poliinfo-4 Task

The omuokdlb team participated in two subtasks in NTCIR 17 QA Lab-Poliinfo-4: Question Answering-2 and Answer Verification. In Question Answering-2, we use Bidirectional Encoder Representations from Transformers (BERT) to match the question summary and the answer utterances. Then, we generated a summary of the answer to the question by using Text-to-text Transfer Transformer (T5). In Answer Verification, we created binary classifiers using BERT to determine whether or not answers, and we confirmed the effectiveness of the combination of the training data.
