I'm guessing you are trying to make sentiment analysis (NLP) on Newswires data source. If there is a public API, you can queried data directly. If not, you would need to write your own crawler. Then you can save the data locally, or upload them to cloud like BigQuery. For a lazy solution, you can then connect your BigQuery dataset to AutoML

But if you want to train your own model, you can try picking some from HuggingFace, or follow paper trails from paperswithcode
