In this task, you will be shown a conversation and a question. You should categorize the question into matching, summary, logic, arithmetic and, commonsense groups. Matching is a question entailed or paraphrased by exactly one sentence in a dialogue. The answer can be extracted from the same sentence. Questions that cannot be answered by the surface meaning of a single sentence belong to the reasoning category. We further define summary, logic, arithmetic and, commonsense subcategories. Answering summary questions requires the whole picture of dialogue, such as the topic of dialogue and the relation between speakers. We require logical reasoning to answer logical questions. in arithmetic questions Inferring the answer requires arithmetic knowledge. To answer commonsense questions, besides the textual information in the dialogue, we also require additional commonsense knowledge that cannot be obtained from the dialogue. Note that a question can be in more than one group. "W" and "M" in the conversations stand for "woman" and "man".
