Abstract: This paper provided a detailed discussion on one fuzzification of Choquet integral which supports fuzzy-valued integrand and gave crisp-valued integration result．It is a generalized Choquet integral for fuzzy-valued integrand,interval-valued integrand,as well as the crisp-valued integrand．The presented generalized Choquet integral with respect to signed fuzzy measure can act as an aggregation tool which is especially useful in many information fusing and data mining problems (such as regression and decision making) where not only crisp data but also heterogeneous fuzzy data are involved.

Key words: Choquet integral,Fuzzy data,Fuzzy measure,Aggregation
