Wait until the information is fully gathered and of a high quality before I use it, even if it takes a while. View an immediate response and have the information update itself while I look at it as better information becomes available. View an immediate response and not have it change while I look at it, but have the option of separately viewing the new, better information when it becomes available. Often people must use information that is changing. For example, journalists receive many new stories and story revisions over the wire.
Traders work amongst rapidly changing stock prices.
Clustering is a process designed to make large amounts of information more easy to understand. Given a set of documents, it groups together similar documents. For example, a search on apple may be clustered into results about the fruit apple, and about the Machintosh computer. Sometimes the clustering process can be slow. When a set of documents is clustered, I want to see results quickly, even if it is a low quality clustering.
