Advertisement detection method, advertisement detection apparatus, and storage medium

A computing device, comprising:

• one or more processors;
• memory;
• a display;
• and
• a plurality of instructions stored in the memory that, when executed by the one or more processors, cause the one or more processors to perform the following operations:
• extracting a plurality of characteristics from a sample set, including extracting a respective characteristic of each advertisement sample in the sample set;
• for each characteristic of the extracted plurality of characteristics:
• determining different types of advertisements carried in advertisement samples in the sample set matching the characteristic, and
• determining characteristic values of the characteristic that correspond to the different types of advertisements, each of the characteristic values representing a probability that the characteristic is an advertisement characteristic of a corresponding type of advertisements, including:
• determining, for each type of advertisements, a quantity of advertisement samples in the sample set that match the characteristic and carry the corresponding type of advertisements, and
• determining, based on the quantity, a characteristic value of the characteristic corresponding to the corresponding type of advertisement;
• and
• filtering, based on characteristic values of the characteristic that correspond to the different types of advertisements, the extracted plurality of characteristics to obtain respective advertisement characteristics of the different types of advertisements;
• matching the advertisement characteristics of the different types of advertisements against characteristics extracted from a to-be-detected sample;
• and
• determining, when a match is found based on the matching, that the to-be-detected sample carries an advertisement, and carries an advertisement of a type corresponding to a matching advertisement characteristic.

A non-transitory computer-readable storage medium storing a plurality of instructions configured for execution by a computing device having one or more processors and a display, wherein the plurality of instructions cause the computing device to perform the following operations:

• extracting a plurality of characteristics from a sample set, including extracting a respective characteristic of each advertisement sample in the sample set;
• for each characteristic of the extracted plurality of characteristics:
• determining different types of advertisements carried in advertisement samples in the sample set matching the characteristic, and
• determining characteristic values of the characteristic that correspond to the different types of advertisements, each of the characteristic values representing a probability that the characteristic is an advertisement characteristic of a corresponding type of advertisements, including:
• determining, for each type of advertisements, a quantity of advertisement samples in the sample set that match the characteristic and carry the corresponding type of advertisements, and
• determining, based on the quantity, a characteristic value of the characteristic corresponding to the corresponding type of advertisement;
• and
• filtering, based on characteristic values of the characteristic that correspond to the different types of advertisements, the extracted plurality of characteristics to obtain respective advertisement characteristics of the different types of advertisements;
• matching the advertisement characteristics of the different types of advertisements against characteristics extracted from a to-be-detected sample;
• and
• determining, when a match is found based on the matching, that the to-be-detected sample carries an advertisement, and carries an advertisement of a type corresponding to a matching advertisement characteristic.
