sub:paragraph c4o:hasContent "We surprisingly observed that the full-stack pipeline outputs a significant amount of noisy chunks, besides being the slowest strategy. On the other hand, the cus- tom chunker was the fastest one, but still too noisy to be crowdsourced. EL resulted in the best trade-off, and we adopted it for the final task. Obviously, noise cannot be automatically eliminated: we cast such validation to the crowd by allowing the None answer along with the candidate FE labels." ;
