Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enforcing category diversity of points of interest (POIs). In one aspect, a method includes receiving a request to identify POIs, obtaining data identifying (i) POIs that satisfy the request, (ii) a category associated with each POI, and (iii) a non-scaled score associated with each POI, and ranking, for each category, the POIs based on the non-scaled scores. The method also includes scaling, for each of one or more categories, the non-scaled scores of the ranked POIs associated with the category, ranking the POIs using the scaled scores, for the POIs that are associated with the one or more categories, and the non-scaled scores, for the POIs that are not associated with the one or more categories, and providing data that identifies the POIs, as ranked according to the scaled and the non-scaled scores. |

1. A computer-implemented method comprising:
receiving a request to identify points of interest (POIs) associated with a geographic location identified in the request; obtaining data identifying (i) candidate points of interest (POIs) associated with the geographic location that satisfy the request, (ii) a respective category associated with each candidate POI, and (iii) a non-scaled score associated with each candidate POI; scaling, for each of one or more particular categories and based on a respective number of candidate POIs associated with each of the one or more particular categories, the non-scaled scores of the candidate POIs associated with the one or more particular categories; ranking the candidate POIs using (i) the scaled scores, for the candidate POIs that are associated with the one or more particular categories, and (ii) the non-scaled scores, for the candidate POIs that are not associated with the one or more particular categories; and providing data that identifies two or more of the candidate POIs, as ranked according to the scaled scores and the non-scaled scores. |
