Query: A Fuzzy Logic Based Certain Trust Model for E-Commerce   Trustworthiness especially for service oriented system is very important
topic now a day in IT field of the whole world. There are many successful
E-commerce organizations presently run in the whole world, but E-commerce has
not reached its full potential. The main reason behind this is lack of Trust of
people in e-commerce. Again, proper models are still absent for calculating
trust of different e-commerce organizations. Most of the present trust models
are subjective and have failed to account vagueness and ambiguity of different
domain. In this paper we have proposed a new fuzzy logic based Certain Trust
model which considers these ambiguity and vagueness of different domain. Fuzzy
Based Certain Trust Model depends on some certain values given by experts and
developers. can be applied in a system like cloud computing, internet, website,
e-commerce, etc. to ensure trustworthiness of these platforms. In this paper we
show, although fuzzy works with uncertainties, proposed model works with some
certain values. Some experimental results and validation of the model with
linguistics terms are shown at the last part of the paper.
