The SPARQL Query Graph Model for Query Optimization [PDF]
, 2007 The Semantic Web community has proposed several query languages for RDF before the World Wide Web Consortium started to standardize SPARQL. Due to the declarative nature of the query language, a query engine should be responsible to choose an efficient evaluation strategy.

XPath whole query optimization [PDF]
Proceedings of the VLDB Endowment, 2010 Previous work reports about SXSI, a fast XPath engine which executes tree automata over compressed XML indexes. Here, reasons are investigated why SXSI is so fast. It is shown that tree automata can be used as a general framework for fine grained XML query optimization.
