Observations

• To train a model on Japanese documents, use either the DocumentUnderstanding package or the InvoicesJapan package.
• To train a model on Chinese documents, use either the DocumentUnderstanding package or the InvoicesChina package.
• To train a model on Latin script documents, use any package except for InvoicesJapan or InvoicesChina.
• For the supported languages, retraining may be required to get the expected accuracy if the documents are considerably different from the original model training dataset.
• For the supported languages which are not pre-trained by the model, you can train a model with your own data in AI Center, assuming the OCR engine supports it as well.
• Automatic reformatting of dates in a standard yyyy-mm-dd format for Asian languages is currently supported only for Japanese. For documents in other Asian languages, you can extract the dates as String content type and format it in the RPA workflow.
