Abstract

In this paper, a fuzzy expert system-based Knowledge Sharing Trust Level measurement adoption model is presented. The KSTL was modeled using four input variables, developed from Technology Acceptance Model constructs: namely, Perceived Trust Toward Competence, Perceived Trust Toward Benevolence, Perceived Trust Barrier for Sharing, External Cue Toward Trust, to determine KSTL. A KSTL-fuzzy algorithm was developed using a trust metric equation at the preprocessing stage and implemented using Matlab 7.6.0 to compute KSTL crisp_value. The results obtained provided a useful understanding about the degree of trust among Community of Practice practicing knowledge-sharing. The proposed work was found to be dynamic, as the computed KSTL fluctuates with changes in the input variables. The simulated results demonstrate the effectiveness of the model in measuring trust level in knowledge-sharing applications.
