Method and Apparatus for Acquiring a Common Interest-Degree of a User Group
A method of acquiring a common interest-degree of a user group for a program, wherein each user of the user group corresponds to a user profile, and the method includes the following steps: receiving a program, which contains at least one content feature; acquiring like-degree, compromise-index and user weight of the user for the said content feature from the user profile; adjusting the user's like-degree for the content feature, with combination of user weight and comprise-degree of each user; acquiring the common interest-degree of the user group for the program according to the adjusted like-degree. In this invention, the compromise indexes of the various users, who are watching certain program, are adopted to adjust the corresponding user weights, so as to acquire the common interest-degree of the user group more accurately and comprehensively.
1 . A method for acquiring a common interest-degree of a user group for a program, each user of the user group corresponding to a user profile, which method comprises the following steps:
(a) receiving a program, which contains at least one content feature;
(b) acquiring a like-degree, compromise index and user weight of the user for said content feature from said user profile of each user;
(c) adjusting the user's like-degree for said content feature in combination with the user weight and compromise index of each user; and
(d) acquiring the common interest-degree of the user group for the program according to the adjusted like-degree.
2 . The method as claimed in claim 1 , wherein said compromise index is used to indicate the attitude of each user in said user group taken against the content feature for the whole interest of the user group, which attitude includes compromise, non-compromise and indifference.
3 . The method as claimed in claim 1 , wherein said user weight is used to indicate the importance of each user in the user group.
4 . The method as claimed in claim 1 , wherein the step (c) includes the following steps:
(c1) adjusting said user weight, according to said compromise index so as to acquire the adjusted user weight; and
(c2) adjusting said like-degree according to said adjusted user weight, so as to acquire the like-degree of each user for said content feature after said adjustment.
5 . A method for recommending program to a user group, each user of the group corresponding to a user profile, which method comprises the following steps:
(a) receiving a program, which contains at least one content feature;
(b) acquiring a like-degree, compromise index and user weight of the user for said content feature from said user profile of each user;
(c) adjusting the user's like-degree for said content feature in combination with the user weight and compromise index of each user;
(d) acquiring a common interest-degree of the user group for the program according to the adjusted like-degree; and
(e) deciding whether to recommend the program to the user group according to the common interest-degree of the user group for the program.
6 . The method as claimed in claim 5 , wherein the said compromise index is used to indicate the attitude of each user in said user group taken against the content feature for the whole interest of the user group, which attitude includes compromise, non-compromise and indifference.
7 . The method as claimed in claim 5 , wherein the step (c) comprises the following steps:
(c1) adjusting said user weight according to said compromise index so as to acquire the adjusted user weight; and
(c2) adjusting said like-degree according to said adjusted user weight, so as to acquire the like-degree of each user for said content feature after said adjustment.
8 . An apparatus for acquiring a common interest-degree of a user group for a program, each user in the user group corresponding to a user profile, the apparatus comprising:
receiving means for receiving a program, which contains at least one content feature;
acquiring means for acquiring a like-degree, compromise index and user weight of each user for said content feature from the user profile of the user;
adjusting means for adjusting the like-degree of the user for said content feature in combination with the user weight and compromise index of each user; and
common interest-degree analyzing means, for acquiring the common interest-degree of the user group for the program according to the adjusted like-degree.
9 . The apparatus as claimed in claim 8 , the adjusting means further comprises:
first-adjusting means for adjusting said user weight according to said compromise index so as to acquire the adjusted user weight; and
second-adjusting means for adjusting said like-degree according to said adjusted user weight so as to acquire the like-degree of each user for said content feature after said adjustment.
10 . An apparatus for recommending information to a user group, in which group each user corresponds to a user profile, the apparatus comprising:
receiving means for receiving a program, which contains at least one content feature;
acquiring means for acquiring a like-degree, compromise index and user weight of each user for said content feature from the user profile of the user;
adjusting means for adjusting the like-degree of the user for said content feature in combination with the user weight and compromise index of each user; and
common interest-degree analyzing means, for acquiring the common interest-degree of the user group for the program according to the adjusted like-degree;
recommending means for deciding whether to recommend the common interest-degree of the user group for the program.
11 . The apparatus as claimed in claim 10 , the adjusting means further comprises:
first-adjusting means for adjusting said user weight according to said compromise index, so as to acquire the adjusted user weight; and
second-adjusting means for adjusting said like-degree according to said adjusted user weight so as to acquire the adjusted like-degree of each user for said content feature after said adjustment.
