Abstract: A method for presenting stories includes creating clusters of documents. Each cluster corresponds to a story. A computer processor generates, for each cluster, a global ranking of social networking messages about the story. The method further includes identifying, for each cluster, a representative social networking message according to the global ranking, selecting, by the computer processor, for a user, a subset of the clusters, and presenting, to the user, the representative social networking message for each cluster in the subset of the clusters.

Abstract: The invention relates to systems and methods of delivering items purchased from a gift registry based on user-defined delivery parameters, allowing users to request currency items as gifts, and exchanging items for other items, and providing group purchase items. The system may receive from a recipient user an identification of one or more items to be added to the gift registry and one or more delivery parameters that indicates a delivery date used to time delivery of the one or more items. When an item is purchased by others for the recipient user, the recipient user may elect to retain the purchased item, exchange the purchased item for another item, or transfer a currency value of the purchased item to a financial account. One or more items of the gift registry may also be flagged as a group item, in which multiple giving users may together purchase the group item.
