Similarities between pairs of experts are computed at level of assessment, as alpha-degrees of sufficient agreement. Consensus degrees are obtained at different levels from such similarities, based on quantifier-guided OWA aggregation. The feedback mechanism identifies the pairs of alternatives with lowest degree of agreement, and then generates recommendations for experts.
