I have very large tables of data that include a 'comments' column, which I am working with in Biolabs Orange.

I need to select only rows that contain a list of keywords (e.g., selected using the word cloud widget, or imported separately) - I will then perform data analysis just on this subset.

What's an efficient way to do this in Orange?

  • $\begingroup$ Maybe a better way to ask: If I have a list of keywords, how can I select an index from an Orange dataframe, using a regex filter on a text column? $\endgroup$ – Shawn May 25 '19 at 15:58
