Cookie correction system and method

摘要

Cookie correction methods, systems, and computer programs include receiving a first cookie from a user via a browser; receiving additional cookies from the user via the browser within a time period and setting the additional cookies as cookies of a first type that are indicative of a unique user; sampling traffic that has accessed a web site by selecting accesses that were made with cookies of the first type within the time period; scaling up the traffic to account for cookies of a second type that have accessed the web site within the time period, the cookies of the second type being indicative of non-unique users which are different than the cookies of the first type; and determining a number of users who have accessed the web site within the time period based on the scaled up traffic.

主权项

1. A computer-implemented method for estimating statistical data, comprising:
receiving, by a data processing system having one or more processors, a plurality of cookies including a first set of cookies and a second set of cookies, each of the first set of cookies corresponding to a query received with an associated cookie and including an initialization time stamp indicating when the cookie was created and a request time stamp corresponding to an action within a predetermined time period that generates an advertisement auction; determining, for each of the first set of cookies, a time difference between the request time stamp and the initialization time stamp of the cookie; selecting, from the first set of cookies, a second set of cookies, the time difference of each cookie of the second set of cookies between the request time stamp and the initialization time stamp exceeding a first predetermined length of time and below a second predetermined length of time, each of the second set of cookies corresponding to a respective unique user identifier;determining a first number of unique user identifiers associated with the second set of cookies; and
estimating, by the data processing system, a second number of unique user identifiers that accounts for unselected cookies from the plurality of cookies by multiplying the first number of unique user identifiers with a ratio of (i) a number of cookies in the plurality of cookies or a number of cookies in the first set of cookies (ii) over a number of cookies in the second set of cookies.
