Abstract:

A new evaluation method of user behavior trust by adopting social characteristics of trust and computer requirements for assessment is proposed. This method improves the sliding window, and makes reasonable calculation of user behavior evidence through the initial setting of the sliding window, the size of the window, the interval of the sliding and the update of the window content, so as to improve the scalability of the user behavior evaluation. Meanwhile, combined with the recommended trust mechanism to further enhance the credibility of user behavior assessment. Finally, the trust value of the user behavior obtained is compared with the default trust evaluation standard of the system to obtain the user trust level. Finally, through the experimental data analysis, the evaluation method has the characteristics of finer granularity, the evaluation object is the user rather than the service provider, and the evaluation result is more in line with the actual situation.

Key words: sliding window, recommendation trust, user behavior trust assessment, credibility and scalability
