This is the default format and also the export format of data labelling tool in AI Center, and this model will read all files in a provided directory with a `.json` extension using the following JSON format when the environment variables are set as follows: * **dataset.input_format** to `ai_center` * **dataset.input_column_name** to `data.text` * **dataset.output_column_name** to `annotations.ner.labels` ### Bug fixes * Several accessibility issues have been fixed.
