Abstract:
The popularization of the World Wide Web (WWW) has given rise to new services every day, demanding mechanisms to ensure the credibility of these online services. Since now, little has been done to measure and understand the credibility of this complex Web environment, which itself is a major research challenge. In this work, we use logistic regression to design and evaluate the credibility of a Web application. We call a credibility model a function capable of assigning a credibility value to transaction of a Web application, considering different criteria of this service and its supplier. In order to validate our proposed methodology, we perform experiments using an actual dataset, from which we evaluated different credibility models using distinct types of information sources, and it allows to compare and evaluate these credibility models. The obtained results are very good, showing representative gains, when compared to a baseline. The results show that the proposed methodology ar
e promising and can be used to enforce trust to users of services on the Web.
