The idea behind the system was that the rich profiles collected for people could be used in summaries of later news in order to generate informative descriptions.
the collection of information about entities from different contexts and different points in time leads to complications in description generation; for example, past news can refer to Bill Clinton as Clinton, an Arkansas native, the democratic presidential candidate Bill Clinton, U.S. President Clinton, or former president Clinton and it is not clear which of these descriptions are appropriate to use in a summary of a novel news item.
