Top-K queries over Web based data sources

Summary: Top-K join also known as rank join, computes 'K' join results with the highest aggregate score from the data sources. The top-K join manages to report these 'K' join by accessing a subset of data from the data sources, provided the data source provide the data in sorted order. I am currently working on accessing top-K join results from the Web based data sources, with main focus on Web services as data sources. The main issue with such Web based data sources is the time utilized in the data acquisition. I am working on the approaches to reduce this data acquisition time, while keeping the amount of data to be retrieved to be close to the optimal.
