The increase in the dependence on World Wide Web has made usability of websites a critical issue. Amongst the various factors affecting the usability, trust of a user on a site assumes a significant role as a trustworthy site ensures user revisit and vice-versa. However, it has been observed that although users can specify their preferences about the features in a particular website, yet they find it difficult to articulate as what makes them trust a website. We therefore need a method to identify the most significant factor which affects the trust the user places on a website.
This paper relates usability features and trust factors by employing Intuitionistic fuzzy sets (IFS). Since human behavior has always remained a complex phenomenon to explain, it is best measured by fuzzy logic. IFS is an extension of fuzzy logic, to capture the uncertainty in a user opinion, a key component of usability research. User opinion was obtained for different users spanning all kind of age groups, to eliminate any age bias. It was found that the users commonly preferred to trust websites, which had a good reputation, followed by sites with good appeal and competence. Identification of this factor is a milestone in the field of usability as it holds the key to improvement in usability of websites.
