I am working in emotion analysis of tweets. I collected close to .6 million tweets. I dont want to label them manually, instead i coded a bunch of complex rules to arrive at their label. Before I use these algo generated labels for my ML solutions, I want to check/analyze how good is this labeling. Are there any statistical/otherwise tests that I can run to understand the quality of the labeling I get from my code.
