Calibrating click duration according to context

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining short click measures and long click measures on a per-category basis. In one aspect, a method includes determining, for each of a set of categories, a respective first threshold click duration that is a long click duration that defines a period of time for which click durations resulting from selections of resources that belong to the category and that meet the first threshold click duration are classified as long clicks, and a respective second threshold click duration is a short click duration that defines a period of time for which click durations resulting from selections of resources that belong to the category and that do not meet the second threshold click duration are classified as short clicks.

1. A method performed by a data processing apparatus, comprising:
identifying user click durations for resources corresponding to a first resource quality measure and identifying user click durations for resources corresponding to a second resource quality measure that is different from the first quality measure, each of the user click durations for a resource being a measure of elapsed time that the first resource is displayed at a user device following a selection of the resource; for each of a plurality of resource categories:
determining based on the user click duration from click durations for first resources that are each categorized as belonging to the resource category and that have a quality measure that is within a threshold range of the first resource quality measure, a short click duration specifying a first threshold click duration that is used to classify a user click duration as a short click; anddetermining, based on the user click duration from click durations for second resources that are each categorized as belonging to the resource category and that have a quality measure that is within a threshold range of the second resource quality measure, a long click duration specifying a second threshold click duration that is used to classify a user click duration as a long click; wherein the determined short click durations are different for at least two of the categories, and the determined long click durations are different for at least two of the categories; and classifying a user click duration corresponding to a selection of a resource from one of the categories based, at least in part, on the short click duration and the long click duration for the one of the categories.
