The invention discloses a method, system, and device for evaluating the concentration ability of a sensory assessor. The attention recognition embodied by this method is organically combined with evaluations for three categories of ranking capability, namely, excellent, good and poor. Therefore, sensory assessors displaying high sensibility and poor attention form part of the group possessing excellent ranking capability, while sensory assessors exhibiting moderate sensibility and high attention can be found in the group possessing good ranking capability. Furthermore, sensory assessors displaying fair sensibility and high attention can be found in the group with poor ranking capability. This system can identify the concentration ability of assessors, therefore, providing support for the reliability of ranking results.
