The reason for us not wanting to use Spearman's rank correlation in its original form is that most verbs cannot be construed as fulfilling the telic or agentive roles of a given noun.
if we calculate Spearman's rank correlation over the entire ranking, the high concentration of low-relevance items at the tail of the ranking will have a greater effect on the final correlation value than the items at the top of the ranking, which are the focus of interest in terms of generating a qualia structure.
