Research on personalized recommender service that uses big data has gained considerable attention given the increasing volume of contents being created. This development indicates the need for service providers to collect personal information and content rating data to personalize content recommendations. Previous studies on this topic proposed algorithms to offer improved recommendations using minimal rating data or service designs and increase the number of ratings. However, limited studies have been conducted on the factors that motivate the ratings input of users, as well as the factors that influence their continuous usage of recommender service. The present study explored the factors that motivate users to enter ratings by conducting in-depth interviews with users who use recommender services. The meanings of these ratings were also explored. Results show that the meaning and usage range of ratings differed based on the stage of a user's with utilization of the service. When users input an initial rating, they treat such a rating as a database to save the impression of a past experience. Such a rating is then used as a tool to reflect the current feeling and thoughts of a user. In the end, users were not only interested in their own rating system, but they also actively sought out the meaning of the rating systems of others and utilized them. Users also expressed mistrust in the recommendations of the service because they were aware of the limitation of the algorithms. This study identified a number of practical implications regarding recommender services.

As time gees by, the function and role of website become more important. Therefore, it is very critical to evaluate and improve continuously the website to the purpose. Many previous studies show that some website evaluation factors will influence the user satisfaction and revisit to the website. The website evaluation criteria from the previous studies related to the university library website evaluation were classified into five assessment criteria which are design, contents, user interface, reliability, and site management. In the results, some significant suggestions were found out. User satisfaction is seriously affected by user interface, and user's intention to revisit is influenced by contents and reliability, but there may not be a close connection between them. Besides, the evaluation method in this study may be applicable to the new website-improving approach of website administrators and researchers.
