The HUKB team participated in the Question Answering-2 subtask in the NTCIR-17 QA Lab-PoliInfo-4 task. Our proposed method is divided into three steps. First, we found the sentence on the beginning of the same topic as the input question from the respondent’s utterances and extracted the candidate sentences. Next, we found the sentences where the respondent seemed to answer the input question directly, using BERT. Finally, we entered the selected sentences with the input question into the T5 based summarizer, and generated the answer summary. We evaluated the whole method and each process with the dataset distributed by Task Organizers.
