1. A method for conversation management in a virtual world data processing system, the method comprising: recording a sequence of statements from different avatars in a virtual world; locating a position of each of the avatars in the virtual world; computing a temporal proximity of each of the recorded statements to others of the recorded statements; grouping selected ones of the recorded statements in the virtual world if corresponding ones of the avatars are geographically proximate to one another in the virtual world and if the selected ones of the statements have occurred within a threshold temporal proximity of one another; and, persisting the grouped statements in the virtual world as a conversation.
