Abstract: Disclosed herein are systems, methods, and software to enhance the user experience with collaboration services. In at least one implementation, the presentation of a user interface to a collaboration service is enhanced by identifying collaboration sites associated with a user and identifying events that occurred with respect to the collaboration sites. Active summaries are then surfaced in the user interface that correspond to the collaboration sites associated with the user. In addition, active elements are surfaced in the active summaries that are indicative of at least the events that occurred with respect to the collaboration sites associated with the user.

Abstract: Architecture that employs a search engine to unobtrusively understand the concepts (topics) and entities in which a user is interested, while simultaneously understanding the current events of the world. These concepts/entities and current events are then mapped to each other to provide a personalized experience for each user that is informative as to the latest news of interest to the user. The user interests are mapped to current events, and queries are formulated, ranked, and displayed to the user that relate to what the user may be interested in searching about new events the user would not have considered without the search engine's assistance. The popular queries are combined with the understanding of what is being indexed in a super fresh tier to determine the current events.
