Fusion of Qualitative Beliefs Based on Linguistic Labels
In order to model beliefs expressed by natural language, the qualitative belief assignment based on the linguistic labels has been presented in the DezertSmarandache Theory (DSmT). However, the combination of qualitative beliefs is only based on the equidistant linguistic labels and the calculation of non-equidistant labels is approximate. To solve the fusion problem of qualitative beliefs denoted by non equidistant labels, this paper proposed the universal arithm etic operations of linguistic labels, and analyzed the fusion of qualitative beliefs based on the general labels. The new operations which were based on the linear or nonlinear mapping relationship between linguistic labels and numerical values, could be efTectively used on 1-tuple or 2tuple linguistic representation model, and could increase the precision and reliability of the combination of qualitative beliefs or mixed beliefs. The experimental results have proved the validity of universal operations.
