Determining matching degrees between information categories and displayed information

摘要

Determining matching degrees of information categories and displayed information is disclosed. In some embodiments, recorded user selection action information with respect to displayed information is analyzed to determine which pieces of displayed information have been selected and which pieces were displayed but not selected. In some embodiments, a matching degree for an information category is determined based on the recorded user selection information with respect to displayed information. In some embodiments, based on this matching degree determined for the information category, it is determined whether the information to be displayed for the information category is to be adjusted for a subsequent event in which information of the information category is to be displayed.

主权项

1. A system for determining matching degrees of information categories and displayed information, comprising:
one or more processors configured to:
retrieve historical user selection action information associated with a plurality of pieces of displayed information corresponding to a plurality of information categories;identify those of the plurality of pieces of displayed information that comprise pieces of displayed and selected information and those of the plurality of pieces of displayed information that comprise pieces of displayed but not selected information based on the historical user selection action information; andfor one of the plurality of information categories:
assign a first primitive weighting to each piece of displayed and selected information associated with the information category and a second primitive weighting to each piece of displayed but not selected information associated with the information category;assign a first correspondence weighting to the information category, wherein the first correspondence weighting comprises a preset value;assign a second correspondence weighting to the information category, wherein the second correspondence weighting is determined based at least in part on a number of pieces of displayed but not selected information associated with the information category and a total number of pieces of displayed but not selected information associated with the plurality of pieces of displayed information;determine a matching degree for the information category and those of the plurality of pieces of displayed information associated with the information category based at least in part on the first primitive weighting, the second primitive weighting, the first correspondence weighting associated with the information category, and the second correspondence weighting associated with the information category; anddetermine whether to adjust information to be displayed for the information category based at least in part on the matching degree determined for the information category; and one or more memories coupled to the one or more processors and configured to provide the one or more processors with instructions.
