From the above scenerio the given data structure is unstuctured why because the given sentiment classes are positive 12k and negative 5k and neutral 3k ..there must be data inbalanced in we try to build ML Model it will show a lot of difference precesion and recall…
so we have to apply under sampling technique to positive class and make it 5k and build ML model
