['[EMPTY]', '[BOLD] Non-experts MCC', '[BOLD] Experts MCC']
The same can probably be said for the “qEcAd” and “qEcAzAcAd” chains: while the former does worse against expert annotations, and the latter does better against non-expert annotations, it could only be indicative of noise in the data. The scores of the keyword heuristic, on the other hand, have seen a significant uptick, especially against non-expert annotations, where performance has more than doubled.
