How WebCQ works

Object extraction algorithms are explored to locate, identify objects of interest in web pages Change detection algorithms are used to detect changes to arbitrary objects in the web pages of interest Difference generation algorithms are exploited to compute how a page is changed and what are the types of changes Difference presentation mechanisms are explored to provide richer and pleasant display of changes Proxy cache service is provided to minimize access latency, reduce the workload of remote information servers, and achieve higher robustness of the WebCQ change monitoring service Notification service is offered with a set of enhanced capabilities to provide both server-initiated push delivery and client-initiated pull delivery of changes
