Method and system for delivering information with caching based on interest and significance

A method ( 200 ) for delivering information (for example, monitoring data) is proposed. The information is collected ( 235 ) on a central server ( 110 ) from remote sources ( 105 ), in order to be provided to multiple clients ( 120 ) in response to corresponding requests. In the method of the invention, an interest index is calculated ( 280 ) according to the number of preceding requests of the information that have been submitted in the past (so as to estimate the interest of the clients for the information); moreover, a significance index is calculated ( 220 ) according to a probability of a current value of the information that is uploaded onto the server by the corresponding source (so as to estimate its importance for the clients). A frequency for refreshing the information on the server can then be determined ( 245 ) according to both the interest index and the significance index. In this way, the refresh frequency self-adapts to the expected behavior of the clients.
