The pair of speakers KI-KA is in the top quin-tile ( > 13.6 % ) . Based on this evidence we can conclude the following : ExpDisagreementDRX ( KI , KA , 5 , dialogue-1 ) which may be read as follows : speakers KI and KA have the highest level of expressive disagreement in dialogue-1 . This measure is complemented by a Cumulative Disagreement Index ( CDX ) , which is computed for each speaker as a percentage of all Disagree-Reject utterances in the discourse that are made by this speaker . Unlike DRX , which is computed for pairs of speakers , the CDX values are as-signed to each group participant and indicate the degree of disagreement that each person generates .
