Filtering information using targeted filtering schemes
First Claim
1. A method implemented by one or more computing devices, the method comprising:
- generating a plurality of filtering schemes including first multiple filtering schemes and second multiple filtering schemes, wherein;
the first multiple filtering schemes are defined using first user-characteristic parameters to target different types of users and are different from each other in using different variables for defining the first multiple filtering schemes,the second multiple filtering schemes are defined using second user-characteristic parameters to target a same type of users, and have a same set of variables and different threshold values to provide different emphasis on respective filtering effectiveness of the second filtering schemes;
the first user-characteristic parameters and the second user-characteristic parameters are generated from one or more targeted keywords and targeted user-characteristic data extracted from a data collection of targeted users;
obtaining one or more keywords and user-characteristic data of a user;
selecting a filtering scheme from the plurality of filtering schemes based at least in part on a correspondence relationship among the filtering scheme, the one or more keywords and the user-characteristic data, wherein the correspondence relationship is determined by comparing the one or more keywords and the user-characteristic data of the user with one or more user-characteristic parameters corresponding to the selected filtering scheme; and
assigning a score to the user based at least in part on the selected filtering scheme; and
filtering information of the user according to the selected filtering scheme to prevent the user from circulating undesired information to other users in response to determining that the score of the user score exceeds a preset threshold.

Abstract
A method for filtering user information takes into account not only specific keywords in the user information, but also related user-characteristic data (e.g., user activity data), and allows targeted user characteristics to be determined from multiple aspects of user activities. In one aspect, the disclosed method adopts different filtering schemes for different types of targeted users to improve the recognition accuracy with respect to the target user information. The method determines a suitable filtering scheme using a correspondence relationship between the filtering scheme and keywords and user-characteristic data. The method uses modeling of sample users and multiple candidate filtering schemes to formulate targeted filtering scheme. An apparatus for implementing the method is also disclosed.
