title = "Query optimization for complex path Queries on XML data",
abstract = "With the proliferation of XML data and applications on the Internet, efficiently XML query processing techniques are in great demand. Many path queries on XML data have complex structure with both structural and value constraints. Existing query processing techniques can only process some part of such queries efficiently. In this paper, a query optimization strategy for complex path queries is presented. Such strategy combines index on values, structural index and join on labeling scheme and generates effective query plan for complex queries. Experimental results show that the optimization strategy is efficient and effective; our method is suitable for various path queries with value constraints and our method scales up for large data size with good query performance.",
