数据格式这么可以吗
{"id": "2840", "text": ["山", "西", "省", "残", "联", "理", "事", "长", "苏", "高", "文", "说", "：", "“", "扶", "持", "残", "疾", "人", "解", "决", "温", "饱", "，", "不", "是", "残", "联", "一", "家", "的", "事", "情", "，", "而", "是", "由", "全", "社", "会", "共", "挑", "的", "担", "子", "。"], "labels": ["B-ORG", "I-ORG", "I-ORG", "I-ORG", "I-ORG", "O", "O", "O", "B-PER", "I-PER", "I-PER", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "B-ORG", "I-ORG", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "O"]}
