document: Dynamic coordination of information management services for processing dynamic web content Dynamic Web content provides us with time-sensitive and continuously changing data . To glean up-to-date information , users need to regularly browse , collect and analyze this Web content . Without proper tool support this information management task is tedious , time-consuming and error prone , especially when the quantity of the dynamic Web content is large , when many information management services are needed to analyze it , and when underlying services\/network are not completely reliable . This paper describes a multi-level , lifecycle ( design-time and run-time ) coordination mechanism that enables rapid , efficient development and execution of information management applications that are especially useful for processing dynamic Web content . Such a coordination mechanism brings dynamism to coordinating independent , distributed information management services . Dynamic parallelism spawns\/merges multiple execution service branches based on available data , and dynamic run-time reconfiguration coordinates service execution to overcome faulty services and bottlenecks . These features enable information management applications to be more efficient in handling content and format changes in Web resources , and enable the applications to be evolved and adapted to process dynamic Web content .
