System for taking action with respect to a media work

摘要

A computer system comprising one or more processors and computer-readable media operatively connected thereto, having stored thereon instructions for carrying out the steps of: maintaining one or more databases comprising first electronic data comprising digitally created reference compact electronic representations for each of a plurality of reference electronic works and second electronic data associated with the reference electronic works and related to action information corresponding thereto; obtaining a first digitally created compact electronic representation comprising one or more extracted feature vectors of a first electronic work; identifying a matching reference electronic work by comparing the first digitally created compact electronic representation of the first electronic work with the first electronic data using a sub-linear search of the first electronic data; determining the action information corresponding to the matching reference electronic work based on the second electronic data; and associating the determined action information with the first electronic work.

主权项

1. A computer system of one or more computers comprising:
(a) one or more processors; and (b) one or more computer-readable media operatively connected to the one or more processors and having stored thereon instructions for carrying out the steps of:
(1) maintaining, by the computer system, one or more databases stored on the computer-readable media comprising
(i) first electronic data comprising one or more digitally created reference compact electronic representations for each of a plurality of reference electronic works, wherein each digitally created reference compact electronic representations comprises one or more extracted feature vectors of at least one of the plurality of reference electronic works; and(ii) second electronic data associated with one or more of the reference electronic works and related to action information corresponding to each of the one or more reference electronic works;(2) obtaining, by the computer system, a first digitally created compact electronic representation comprising one or more extracted feature vectors of a first electronic work;(3) identifying, by the computer system, a matching reference electronic work that matches the first electronic work by comparing the first digitally created compact electronic representation of the first electronic work with the first electronic data using a sub-linear search of the first electronic data that identifies a match to the first digitally created compact electronic representation within a threshold but does not guarantee to identify the closest match to the first digitally created compact electronic representation, wherein the first electronic data is organized using a clustering technique to eliminate a subset of the reference compact electronic representations to be searched by performing a comparison of cluster features;(4) determining, by the computer system, the action information corresponding to the matching reference electronic work based on the second electronic data; and(5) associating, by the computer system, the determined action information with the first electronic work.
