Evaluation of Trustworthiness based on Fuzzy Set Theory

چکیده
In the heterogeneous network, trustworthiness of the entity can help other entities to decide whether or not to have a transaction with it. The feedback data used to evaluate trustworthiness always comes from different entities in different system and is expressed in all kinds of forms. This may be easy for entity to express their trustworthiness, but it will increase difficulties of evaluation of trustworthiness. This paper first introduces different express forms used to show trustworthiness of the entities, and then show how to translate different form into fuzzy form using fuzzy set theory, and give a evaluates of integrated data. The experiment data shows that the trustworthiness expressed with fuzzy form is more appropriate, and the method based on fuzzy set is more convenient for the entities to predict the risk.

متن کاملA research on classification performance of fuzzy classifiers based on fuzzy set theory
Due to the complexities of objects and the vagueness of the human mind, it has attracted considerable attention from researchers studying fuzzy classification algorithms. In this paper, we propose a concept of fuzzy relative entropy to measure the divergence between two fuzzy sets. Applying fuzzy relative entropy, we prove the conclusion that patterns with high fuzziness are close to the classi...
