You can use the CONTAINS feature to elicit this information in Tableau, however I'd recommend you do this in your data preparation stage, probably in excel.
Yes it is possible to do so in Tableau also by using CONTAINS function.
Create one calculated field and start writing contains function (i.e If contains('Calculation', 'Basketball') TRUE then 'Sports' ).Please check the syntax while writing the code.
And same for the 'Reviews/Comments' field.
Hope this will help you.
Thanks & Regards
