Updating Model of Software Component Trustworthiness Based on Users Feedback

The software trustworthiness measurement is one of the hot topics. Software component technology is the mainstream technology of software development. How to get the trustworthy degree of software component efficiently and accurately is a challenging issue for the component-based software development. Getting the trustworthy degree of software component needs many users' success cases. In this paper, we propose an updating model of software component trustworthiness. First, the trustworthy degree of the software component is computed based on users' feedback. Then, the weight of updating is determined by the number of users. Finally, the method of cluster different companies is based on the Euler distance. A case study shows that the method is reasonable and effective.
