Topic modeling

Using Jupyter from KNIME: embedding documentsThis workflow demonstrates the use of functionality defined in a Jupyter notebook from inside of KNIME. Afterbuilding a topic model for a set of documents, we use a Python function from a Jupyter notebook to perform t-SNEembedding of the documents into a 2D space. As a final step we do an interactive visualization to allow exploringthe results.The documents used are taken from the Fun with Tags post on the KNIME Blog: https://www.knime.com/blog/fun-with-tagsKNIME Extensions required: - Textprocessing - KNIME Python ScriptingThe Python Scripting integration needs to be configured to use a Python environment that has scikit-learn andjupyter installed.
