    • Canonicalisation of monotone SPARQL queries 
      Salas, Jaime; Hogan, Aidan (Springer Verlag, 2018)
      Caching in the context of expressive query languages such as SPARQL is complicated by the difficulty of detecting equivalent queries: deciding if two conjunctive queries are equivalent is NP-complete, where adding further ...
