[GitHub] [incubator-superset] jzonthemtn opened a new issue #9672: Tokenize text when making a word cloud
jzonthemtn opened a new issue #9672:
URL: https://github.com/apache/incubator-superset/issues/9672
**Is your feature request related to a problem? Please describe.**
When using the word cloud on fields that contain sentences, the word cloud treats each field as a "word" in the word cloud. The word cloud then contains each sentence.
**Describe the solution you'd like**
Have an option to tokenize (or simply split on whitespace) the words in a field.
**Describe alternatives you've considered**
Changing how data gets ingested into the database but I don't see a good solution from that angle if the word cloud is expecting one word per field.
**Additional context**
None.

This is an interesting idea @jzonthemtn . To make sure the proposed feature is as generic as possible, do you have any suggestions for tokenization options? I'm thinking how to handle periods, commas, special characters etc?

@villebro My recommendation would be to strip punctuation and then split on whitespace. This would work well for my use-case. If that is not sufficient for a user then I would suggest they do any necessary preprocessing of the text prior to saving it in their database so that way they have control over how they want to handle the tokenizing.

While this feature would definitely be useful, it’s also pretty easy to create virtual data sources that split strings and explode arrays into rows:
