Json file containing labels not accepted custom NER

Question

I am trying to make a custom NER project using Azure. When I want to use my own file for the tags of the data, it responds "InvalidArgument: Invalid project json object. Could not find member 'extractors' on object of type 'JsonProjectAssets'" when I click create. I've tried different formats I found online and even tried some example files they give in the Quickstart documentation. But I keep receiving the same error. Are they busy with changing the format of the tagged file or am I doing something wrong? I hope someone knows how to fix it!

Answer 1

I ran into this same issue while following the custom text classification quick start guide. I got around the issue by first creating my project in Language Studio with no mapping file (I selected "No, I need to tag my files as part of this project."). Then I used the REST API to add the mapping file. Within the body of the request, you can import the JSON file. I found that the keys need to match the example in the assets object or else I received an error.

"assets": {  
    "classes": [  
      {  
        "category": "string"  
      }  
    ],  
    "entities": [  
      {  
        "category": "string"  
      }  
    ],  
    "documents": [  
      {  
        "location": "string",  
        "language": "string",  
        "class": {  
          "category": "string"  
        },  
        "classes": [  
          {  
            "category": "string"  
          }  
        ],  
        "entities": [  
          {  
            "regionOffset": 0,  
            "regionLength": 0,  
            "labels": [  
              {  
                "category": "string",  
                "offset": 0,  
                "length": 0  
              }  
            ]  
          }  
        ],  
        "dataset": "string"  
      }  
    ]  
  }
