The Web isn’t a static place, where pages remain the same, as search engines try to index and lead searchers to information.
A new patent application from Ask.com explores this stream of data, and trends within it, and how those can be used to improve search rankings and advertisements, as well as supplying searchers with relevant and up to date content.
I would suspect that similar inquiries into trends and burstiness of information happen at other search engines, too.
System and method for monitoring evolution over time of temporal content
