I answered your question on the other topic, linked below. But I also wanted to point out here that if you’re looking for additional resources on how to do text processing and analytics with KNIME, we have a book dedicated to this topic that’s really good.
It’s available in our KNIME Press store, and is called From Words to Wisdom. I’ve gone through the entire book myself and it’s excellent - I’m not just saying that as a KNIME employee!
It should help you get oriented not only with the functions of individual nodes, but also approaches to particular text analysis strategies, whether it’s sentiment analysis, topic extraction, visualization, and even some word embedding.
