A computer-implemented method, the method comprising: obtaining a plurality of episodes from an image library, wherein each episode is associated with a corresponding time period, and includes a respective set of images and person identifiers for each image in the respective set of images, wherein the person identifiers correspond to persons depicted in the respective set of images; forming a plurality of clusters that includes a respective cluster for each episode, wherein each cluster includes at least two person identifiers, wherein identical clusters comprise the same person identifiers, and wherein forming the plurality of clusters that include the respective cluster for each episode comprises mapping, to the cluster, person identifiers that appear in at least one image in the respective set of images of the episode associated with the cluster; determining whether one or more person identifiers are only included in a number of clusters of the plurality of clusters, wherein the number of clusters is less than a threshold number of clusters; if it is determined that the one or more person identifiers are only included in the number of clusters that is less than the threshold number of clusters, removing the one or more person identifiers from the clusters included in the number of clusters; merging the identical clusters to obtain a plurality of people groups, wherein each people group includes two or more person identifiers, wherein merging the identical clusters comprises associating, based on the clusters, a respective set of episodes to each of the plurality of people groups; after the merging, determining that at least one people group appears in a number of episodes of the plurality of episodes that is less than a threshold number; in response to the determination that the at least one people group appears in the number of episodes that is less than the threshold number, combining the at least one people group with one or more other people groups, wherein the one or more other people groups each include a subset of the person identifiers included in the at least one people group; and after the combining, providing a user interface that includes an image-based creation that includes one or more images that depict persons from a particular people group of the plurality of people groups, wherein providing the image-based creation comprises selecting a subset of images for the image-based creation from the respective set of images included in the episodes associated with the particular people group. obtaining a plurality of episodes from an image library, wherein each episode is associated with a corresponding time period, and includes a respective set of images and person identifiers for each image in the respective set of images, wherein the person identifiers correspond to persons depicted in the respective set of images;
