Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for scoring criteria for content items. In one aspect, a method includes identifying a primary ranking signal and a set of auxiliary ranking signals for ranking a set of criteria for a content item. A primary score and a set of auxiliary scores can be identified for each particular criterion in the set of criteria. Each auxiliary score can be adjusted to generate adjusted auxiliary scores. The adjusting can include applying, to at least a portion of the auxiliary scores, a transformation function that reduces an amount of skewness among the auxiliary scores. A ranking score can be determined for each particular criterion based on a function of the primary score for the particular criterion and the adjusted auxiliary scores.

Abstract: Methods, systems, and apparatus for diversifying selection criteria. An example method includes accessing a first set of selection criteria for a content item; selecting, based on the first set of selection criteria, a second set of selection criteria, the second set of selection criteria being a proper subset of the first set of selection criteria, the selection of each of the criteria in the second set comprising: determining a collective performance measure based on criteria that have been selected from the first set of selection criteria for inclusion in the second set of selection criteria, determining, for each criterion that has not been selected from the first set, a performance contribution to the collective performance measure, and selecting from the first set a selection criterion with the highest performance contribution relative to the performance contributions of other selection criteria that have not been selected for inclusion in the second set.
