DETERMINING AND INFERRING USER ATTRIBUTES

摘要

Methods and apparatus for determining and inferring user attributes based on detected user activity are presented. A first user attribute may be determined based on first activity of a user. A second user attribute related to the first user attribute may be inferred. A third user attribute may be determined based on second activity of the user that occurs after the first activity. A confidence associated with the second user attribute may be altered in response to a determination that the third user attribute is related to the second user attribute.

1. A computer-implemented method, comprising:
determining, by a computer system based on activity of a user, a plurality of user attributes associated with the user, wherein one or more of the plurality of user attributes are inferred from other user attributes of the plurality of user attributes; classifying, by the computer system, one or more of the plurality of user attributes as short-term or long term based on corroboration of the respective user attribute over time; receiving, by the computer system after the classifying, a search query submitted from the user using a remote computing device; determining, by the computer system, that the search query relates to a short-term attribute; ranking, by the computer system, search results responsive to the search query in a manner that favors a user attribute classified as short-term over a user attribute classified as long term; and transmitting, by the computer system to the remote computing device, the search results.
