This workflow showcases how the Container Input (Variable) and Container Output (JSON) nodes can be used to create a REST API for a workflow that can then be deployed as inference workflow to KNIME Edge. The workflow can be called via REST and classifies a review as positive or negative. When deployed to KNIME Edge, a POST request with the following JSON body can be used for testing: { "content": "What a crappy flight, I hated it! It was the worst experience ever" } The response will be: { "Prediction (Document class) (Confidence)": 0.7526856112217033, "Prediction (Sentiment)": "Negative" }
