Research and Application on Recommendation Trust Model in Distributed Network System

Abstract

In distributed network, a node requesting recommendation needs to select right recommendation node. This paper puts forward a recommendation trust model. Compared with recommended capacity trust, this model distinguishes service quality trust from it , including nodes’ correlations, frequencies and risk. Among them, correlations are measured by service care and assessment capacity similarity, frequencies and risk are calculated due to various nodes.At last, an example verified the usefulness of this model, and results show that the model not only has high accuracy when select recommendation nodes, but also can improve the nodes interactions’ satisfaction rate.
