Abstract
Disclosed are methods and apparatus for identifying users of content. The methods include identifying contextual information of a group of users, gathering user access data of the users on the basis of the contextual information of the group of users, analyzing temporal information of the user access data, and identifying particular users in the group of users on the basis of the analyzed temporal information and the contextual information.
Claims19
A method of indentifying users of content, comprising the steps of:
- identifying contextual information of a group of users;
- gathering user access data of the users on the basis of the contextual information of the group of users;
- analyzing temporal information of the user access data;
- and
- identifying particular users in the group of users on the basis of the analyzed temporal information and the contextual information.
A method of identifying users of content, comprising the steps of:
- observing temporal patterns of viewing of a group of users over a time frame;
- quantifying the observations of the temporal pattern to obtain an empirical probability distribution of rating events associated with the users over different sub-time frames within the time frame;
- and
- predicting each user's content use behavior based on the quantified temporal observations to obtain a predicted use profile for the users.
A method of identifying users of content, comprising the steps of:
- classifying a set of user ratings of content by approximating a matrix of ratings by a low rank matrix;
- minimizing regularized empirical loss of the matrix of ratings;
- iteratively updating the matrix of ratings and updating the matrix after empirical losses are minimized;
- and
- identifying users based the iteratively updated matrix.
A method of identifying users of content, comprising the steps of:
- identifying contextual information of a group of users;
- gathering user access data of the users on the basis of the contextual information of the group of users;
- analyzing temporal information of the user access data, wherein the contextual information comprises time-stamp information and information related to when a user rating of the content is entered;
- and
- identifying particular users in the group of users on the basis of the analyzed temporal information and the contextual information.
Apparatus for identifying users of content, comprising:
- a processor for identifying contextual information of a group of users, gathering user access data of the users on the basis of the contextual information of the group of users, analyzing temporal information of the user access data, and identifying particular users in the group of users on the basis of the analyzed temporal information and the contextual information.
