| Abstract: | Dirty data such as incorrect data, inconsistent data, imprecise data bring challenges to effective query processing on XML. The paper focuses on processing twig queries on XML with dirty tags. And it separately proposes the principle, pseudo code, correctness proof and complexity analysis of the optimization, examples are also given in the paper. Ultimately, experimental evaluation of efficiency is made on the optimization. |
