Distribution of video in which time period during which product was presented is estimated

An estimation method, comprising

• by a computer:
• receiving, from each of a plurality of terminals which are playing a distributed live video, a piece of access information sent in response to an operation on one of a plurality of objects respectively associated with a plurality of products presented in the live video;
• collecting video identification information identifying the live video, product identification information identifying a product associated with the operated object, and time information indicating a playback time of the live video at the time of operation being performed on the operated object, the video identification information, the product identification information, and the time information being included in each of the received pieces of access information;
• and
• estimating, based on the collected video identification information, product identification information, and time information, a time period during which each of the plurality of products was presented in the live video,
• wherein the estimating comprises:
• aggregating the pieces of access information including the same video identification information and the same product identification information into a same group;
• and
• calculating a distribution curve of numbers of accesses with respect to the playback times for each of the aggregated groups;
• and
• based on determining each boundary between the distribution curves adjacent to each other on a time axis, estimate the time period corresponding to each of the plurality of products.

A distribution system, comprising:

• a server device;
• and
• a plurality of terminals,
• wherein at least one processor of one or more processors included in the server device executes processing of:
• receiving, from each of the plurality of terminals which are playing a distributed live video, a piece of access information sent in response to an operation on one of a plurality of objects respectively associated with a plurality of products presented in the live video;
• collecting video identification information identifying the live video, product identification information identifying a product associated with the operated object, and time information indicating a playback time of the live video at the time of operation being performed on the operated object, the video identification information, the product identification information, and the time information being included in each of the received pieces of access information;
• and
• estimating, based on the collected video identification information, product identification information, and time information, a time period during which each of the plurality of products was presented in the live video,
• wherein the estimating comprises:
• aggregating the pieces of access information including the same video identification information and the same product identification information into a same group;
• and
• calculating a distribution curve of numbers of accesses with respect to the playback times for each of the aggregated groups;
• and
• based on determining each boundary between the distribution curves adjacent to each other on a time axis, estimate the time period corresponding to each of the plurality of products.
