  • Scenarios

    A custom labeling template applies to your specific labeling scenario.

  • Data structures
    • Input data

      {"data":{"picture_url":"oss://tongxin-lly.oss-cn-hangzhou.aliyuncs.com/iTAG/pic/13.jpg","text":"Alibaba Group's 10th anniversary and the founding of Alibaba Cloud"}}

    • Output data
      Each row in the .manifest file of output data contains an object and the labeling results for the object. The following code provides an example on the JSON string in each row: 
      {
    "data": {
        "picture_url": "oss://itag.oss-cn-hangzhou.aliyuncs.com/tongxin_pic/13.jpg",
