Uncertain. Fuzziness Knowl.-Based Syst. 9, Suppl., 17-31 (2001).} \itemab Summary: We study the extension of Choquet integrals to ordinal scales. We show that two different integrals can be defined on the basis of two different but equivalent expressions in the numerical case. We prove some properties of the Choquet integrals and show their application to aggregation. \itemrv{~} \itemcc{} \itemut{aggregation operators; Choquet integral; ordinal scales} \itemli{doi:10.1142/S021848850100096X} \end
