NEP error

[mokcay]

Can anyone help me with this. I am trying to group the rows into various categories. 

I am using Named Entity Recognition. I created a Text Input with one Label with various entities to test if it works. I shall create more labels if this works. But it doesnt. It says:

Error: Named Entity Recognition (109): Some labels don’t have enough data points to train an accurate model. Each of these labels has less than 20 data points: [''].

Or can you suggest another way to group these based on keywords.

Thank you very much!
