Finding Missing Answers due to Object Duplication in XML Keyword Searchject as the child. However, this child object is not discovered by the typical LCA (Lowest Common Ancestor) based approaches in XML keyword search. This may lead to the problem of missing answers in those approaches. To solve this problem, we propose a new approach, in which we model an XML document

A Study on External Memory Scan-Based Skyline Algorithmse past few years the problem has been studied extensively, and a great number of external memory algorithms have been proposed. We thoroughly study the most important scan-based methods, which perform a number of passes over the database in order to extract the skyline. Although these algorithms are
