| Title | Negation in SPARQL |
| Authors | Renzo Angles, Claudio Gutierrez |

| Abstract | This paper presents a thorough study of negation in SPARQL. The types of negation supported in SPARQL are identified and their main features discussed. Then, we study the expressive power of the cor- responding negation operators. At this point, we identify a core SPARQL algebra which could be used instead of the W3C SPARQL algebra. Fi- nally, we analyze the negation operators in terms of their compliance with elementary axioms of set theory. |
