How to use data in database as intention training corpus

intent:search_singer

  • Whose songs do you want to check
  • Whose song would you like to listen to

intent:inform_singer

  • Alan Walker
  • Taylor Swift
  • Lady Gaga

Suppose I have an intent search_singer (FormAction), and I created an intent inform_singer to answer slot (singer). The inform_singer corpus is all singer entities. If it is not possible to list all singers for training, then when the intention classifier sees a singer entity that has not been seen in the training corpus, it will not classify it as inform_singer. Is there a way to use the data in the database as an entity in the intent training data? Or is there any other way besides exhaustion?
