Keyword search provides ordinary users an easy-to-use interface for querying RDF data. Given the input keywords, in this paper, we study how to assemble a query graph that is to represent user's query intention accurately and efficiently.

Then, we formally define the query graph assembly (QGA) problem. Unfortunately, we prove theoretically that QGA is a
