Shangbo Zhou · Jisuanji gongcheng · 2009
This paper proposes a novel e-learning service discovery algorithm——eLSDAUS. A factor of user satisfaction which is the user’s feelings to the result of service discovery is led-in. This algorithm allows users to take part in the process of e-learning service discovery,and allows them to evaluate the result of service discovery. User’s evaluation is fed back to the system. With the help of penalty function,the system modifies the weight of each property of the advertise service,and then total match degree of service discovery up to best. Experiment indicates that the precision of the service discovery improves 4%～5% as the number of advertisement services up to 10 000. After learning for one week,over 93% students are satisfied with the e-learning service discovery result.
