Abstract
Abstract — The existing query languages for XML (e.g., XQuery) require professional programming skills to be formulated, however, learning such complex query languages is a tedious and a time consuming process that can be very challenging especially to novice users. In addition, when issuing an XML query, users are required to be familiar with the content (including the structural and textual information) of the hierarchical XML, which is difficult for common users. The need for designing user-friendly interfaces to reduce the burden of query formulation is fundamental to the spreading of XML community. We present a twig-based XML graphical search system, called LotusX, that provides a graphical interface to simplify the query processing without the need of learning query languages and data schemas and the knowledge of the content of the XML document. The basic idea is that LotusX proposes “positionaware” and “auto-completion ” features to help users to create tree-modeled queries (twig pattern queries) by providing the reasonable candidates on-the-fly. In addition, complex twig queries (including order-sensitive queries) are supported in LotusX. Furthermore, a new ranking strategy and a query rewriting solution are implemented to rank the results and automatically rewrite queries, respectively. I.
