Constructing Inter-relational Rules for Semantic Query Optimisation

  title={Constructing Inter-relational Rules for Semantic Query Optimisation},
  author={Barry G. T. Lowden and Jerome Robinson},
Semantic query optimisation is the process by which a user query is transformed into a set of alternative queries each of which returns the same answer as the original. The most efficient of these alternatives is then selected, for execution, using standard cost estimation techniques. The query transformation process is based on the use of semantic knowledge in the form of rules which are generated either during the query process itself or are constructed according to defined heuristics… CONTINUE READING
