Why are some recommendation systems preferred?

There has been wide interest in exploring ways to provide more efficient personalized recommendation systems (RSs) in order to attract customers and increase product sales. The majority of the existing researches are concerned with improving the accuracy and effectiveness of the recommendation algorithms, or focusing on how to limit perceived risks, with the aim of increasing consumer satisfaction. Unlike these mentioned studies, this research begins from the perspective of customer-RS interaction, and ends in revealing the mechanisms involved in consumers' acceptance of recommendations by using the technology acceptance model. The empirical study results show that perceived interpersonal interaction is an important factor that directly affects university students' intentions to use RS, while perceived ease- of- use influences them in an indirect way through mediation of perceived usefulness. On this basis, the study thus provides suggestions on how to supply an improved interaction with easy and useful personalized RS.
