Drag Workflow
Workflow preview
This workflow helps you to generate and compare a series of topic models from a collection of preprocessed documents. It produces a range of formatted tables and plots with which you can evaluate and compare both the qualitative content and measured coherence of two or more models or model configurations. The outputs are procued with R, so KNIME's R integration capabilities must be activated. This is an 'alpha' release of the workflow. It has not been tested with a variety of users and environemnts, so probably contains bugs, and possible even calculation errors. So use it at your own risk, but please do not hesitate to reach out if you have a question or suggestion for improvement.
