@Justin Thanks for the question. Can you please add more details about the Text analytics version that you are trying. The models are pretrained. We do not host custom models. If you want to create and host custom machine learning models, consider the machine learning capabilities. Please follow the Text Analytics API (v3.1-preview.3) API returns a detailed sentiment analysis for the input text. The analysis is done in multiple levels of granularity, start from the a document level, down to sentence and key terms (aspects) and opinions.
If you have a real dataset (preferably labeled but unlabeled is okay too if you can review the results with us) in any of the supported languages Language support - Text Analytics API - Azure Cognitive Services | Microsoft Learn and have interest in trying out our new Transformer based pre-trained AI models (A holistic representation toward integrative AI - Microsoft Research) – can you please reach out to me to evaluate it?
Your dataset will not be used to re-train the AI models, but we can fine tune the model if the results are not as desired.
