PigReuse

In short: 
Two platform for specifying and exploiting warehouses of RDF data
Description: 

PigReuse is a novel optimization algorithm aiming at identifying and reusing repeated subexpressions in Pig Latin scripts. It identifies subexpression merging opportunities, selects the best ones to execute based on a cost function, and reuses their results as needed in order to compute exactly the same output as the original scripts.
