The prototype of multi-facial recognition technique-aided internet protocol television (IPTV) system named “EyeTV” is introduced in this study. EyeTV applies Xbox's IP camera - KINECT to be the eye of TV for capturing facial features of users, and the multi-facial recognition technique is employed to recognize the user's identity. The users who watch the videos together are taken as a group, and then...
An adaptive correlation-based group recommendation system or recommender is proposed which takes the members' interactions into account. Thus, the proposed method can predict members' relationships by acquiring the correlations between a group and its members. With the predicted correlations, each member's weight can be estimated. Finally, the group's ratings of those non-rated items can be predicted...

Therefore, a kind of special data mining technique appeared, it called Recommender System. Most research of recommender system always provides the most relevant items for users or items. However, recommendations from traditional recommender system may not satisfy the new human beings because...
Cache invalidation is an effective approach to maintaining data consistency between the server and mobile clients in a mobile environment. This paper presents two new cache invalidation schemes which are designed according to the real situations and are therefore able to comply with the more practical needs in a mobile environment. The ABI+HCQU divides data into different groups based on their utilization...
