pyLDAvis for visualiation

did someone integrated the python PyLDAvis in a knime component ? if no could someone help me mplementing it ? thx

Hi and welcome to the KNIME Forum!
I have created a workflow that embeds pyLDAVis. This library is really cool because it can export the visualization as HTML. This allows us to pass that to the Generic JavaScript View, which can also be displayed in the WebPortal. Here is the workflow:

First it creates the pyLDAVis visualization, then it passes the generated HTML on to the Generic JavaScript View. There we just insert the HTML into the page and evaluate the embedded JavaScript.
Kind regards,



I have issues to transform the output of “Topic Extractor (Parallel LDA)” to fit it into the python node / pyLDAviz. Does somebody have an idea how to do it or an example Workflow?

BR and Thanks
