Hi, I am doing research in psychology and trying to use KNIME to analyze my text data. But as I am new to KNIME and its functions, I am stuck and feeling frustrated and would very much appreciate your help. I now have a list of 1000+ items/sentences from different questionnaires. I am trying to identify items/sentences that are similar to each other within the corpus. I have attempted making use of similarity search but I guess I have not set the workflow right – it does not run. So far, I have successfully prepocessed the documents. What nodes can I use after this to be able to identity duplicate documents within the corpus? Can you guide me on this? And if you know of better analytical strategies, I am open to them as well.

Similarity search?

You can try StringSimilarity node or String Matcher node.

Approach - fuzzy match or supervised learning?
