01 Development Workflow

This is a development workflow. During the development of a lexicon based sentiment predictor, you try out different approaches and end up with many branches in the workflow.

Only some of them have to be put into production. You can capture those segments with integrated deployment workflows and save them with the Workflow Writer node.
