The year 2000 saw the climax of the first dot-com bubble.This high-speed internet revolution catalysed wide-spread, global and fundamental changes in the way people use their computer, communicate, make business and strongly influenced the present society. Today in 2007 a similar ambience is brewing on the web. Thousands of new websites appear every hour and new services are launched every day. The competition amongst websites of similar interest is ongoing and those who don’t stay up-to date risk loosing their audience in a very short time. In this day and age of the ever-changing web-fresco, recent trends have seen the emergence of personalised services, where users must create a profile on each website and maintain a regular input to benefit from these customised services. Rapidly users tend to commendation results would not have been such a crucial field of study.
However, a trend has recently emerged where users go to websites to actively seek advice and suggestions for electronic products, vacation destinations, music, books, etc. They interact with such systems as first-time customers and may not get the usual benefit of receiving recommendations “automatically” [12] due to the lack of a personal preference history. Compared to receiving unsolicited recommendations, users who specifically seek recommendations are likely to have a higher level of expectations on the results they obtain and the ease of use of the system. In the seeking context, a user makes a conscious decision to use a system for a specific goal. If they do not find what they are looking for, or the system is too hard to use, they may quickly leave. We therefore argue that as recommender systems are broadening their scope of use, the acceptance process is becoming more complex and pertinent to study. Site designers must somehow identify the right balance between the benefits they offer relative to the effort they require from users in order to increase their ability to attract new users and provide a high level of staying power.
