1. A method comprising: determining, at an apparatus, a context associated with each of a plurality of groups, each of the groups comprising items; determining, at the apparatus, a current context at a device, wherein the current context specifies one or more time conditions and one or more geographic locations associated with the device; causing, at least in part by the apparatus, a generation of at least one relevance metric for the each group based, at least in part, on one or more factors associated with the items; determining, at the apparatus, a multi-dimensional relevance metric of each item of the each group; causing, at least in part by the apparatus, a generation of a group image for the each group based on a number M of images associated with the number M of items that are determined to have a multi-dimensional relevance metric value above a threshold value; in response to a prompt presented for input to indicate at least one of the items, causing, at least in part by the apparatus, a presentation of at least two group images, wherein each of the group images includes a collage of representative images of the each presented group, and the each presented group matches a group multi-dimensional relevance metric threshold value based on the at least one relevance metric; in response to one or more user inputs, generating, at the apparatus, a new group of items using the at least one of the items and one or more of the at least two group images; causing, at least in part, a presentation of the new group; determining, by the apparatus, an update to the multi-dimensional relevance metric of the each item based, at least in part, on a decay factor; updating, by the apparatus, the collage of representative images of the each presented group based, at least in part, on the update to the multi-dimensional relevance metric of the each item; and causing, at least in part by the apparatus, an updated presentation of the at least two group images based on the updated collage of representative images of the each presented group, wherein the representative images of the each presented group are determined as most relevant to the current context at the device, and wherein the presented group images are identical-sized and distinguishable from each other.
