FILTER SELECTION IN SEARCH ENVIRONMENTS
First Claim
1. A computer-implemented method, comprising:
- identifying filter reduction ratios for a plurality of filters, each respective filter reduction ratio corresponding to a respective reduction of training assets based on use of a respective filter;
receiving a requested reduction ratio; and
selecting, by a computing system, a subset of filters from the plurality of filters based at least in part on the requested reduction ratio and the filter reduction ratios, the subset of filters selected such that applying the subset of filters to a set of a number of media assets reduces the number of media assets in the set according to the requested reduction ratio.

Abstract
Techniques for utilizing sets of filters to reduce a large number of searchable assets to a meaningful or reduced number of searchable assets. Feature information may be extracted from a particular asset of a set of training assets to create an artificial term. A reduction ratio may then be calculated by utilizing the created artificial term to filter the set of training assets. The reduction ratio may represent the ratio of training assets that contain a particular artificial term. A plurality of filters and their associated reduction ratios may be created this way by utilizing the set of training assets. This process can also involve receiving a requested reduction ratio associated with a set of searchable assets. A combination of filters may then be selected which, when applied to the set of searchable assets, results in a reduced number of searchable assets according to the requested reduction ratio.

12. A system, comprising:
-
one or more processors; and memory including instructions executable by the one or more processors that, when executed by the one or more processors, cause the system to at least; identify filter reduction ratios for a plurality of filters, each respective filter reduction ratio corresponding to a respective reduction of training assets based on use of a respective filter; and in response to receiving a requested reduction ratio; select a subset of filters from the plurality of filters based at least in part on the requested reduction ratio and the filter reduction ratios, the subset of filters selected such that applying the subset of filters to a set of a number of media assets reduces the number of media assets in the set according to the requested reduction ratio. - View Dependent Claims (13, 14, 15, 16, 17)

18. A non-transitory computer-readable storage medium having stored thereon computer-executable instructions that, when executed by one or more processors of a computer system, cause the computer system to perform operations comprising:
-
identifying reduction ratios for each of a plurality of filters; and selecting a subset of filters from the plurality of filters based at least in part on a particular reduction ratio such that applying the subset of filters to a set of a number of media assets reduces the number of media assets in the set according to the particular reduction ratio. - View Dependent Claims (19, 20)
