Abstract: A device, system, and method are directed towards determining a suggested characteristic for an event. At least two events are determined. In one embodiment, at least one characteristic is determined for one of the event. A plurality of other characteristics is determined for the other event. The characteristics of the two events may be determined implicitly from communications during the events or from user input. Based on a relationship between the determined characteristics, the suggested characteristic for the event is then determined. In one embodiment, the relationship is defined as a match of characteristics. The event may then be modified based on the suggested characteristic. For example, a suggested member may be invited to join the event, or the event's time, location, or name may be changed. If the other event is current or pending, the event and the other event may be combined.
