An Access Cost-Aware Approach for Object Retrieval over Multiple Sources

Summary: Access cost-aware framework for retrieving a target number of objects from multiple data sources. Probabilistic source selection and a dynamic-programming model allocate per-source quotas to minimize total access and retrieval costs; validated on real-world datasets.
