"Regarding the experiments design, my impression is that a number of results are not fully related to the intended characteristics of the experiments (expert vs. laymen crowdsourcing, find vs. verify stage, etc.) but are the collateral effect of non-optimal design choices, in terms of (1) choice of triples/data and quality issues to be tested, (2) user interface and support information provided to participants and (3) reported indicators and baselines." .
