The Crisis of Physical Illness: An OverviewXPath expressions play a central role in querying for XML fragments. We present a containment test of two XPath queries which determines whether a new XPath query XP1 can reuse a previous query result XP2. The key idea is to transform XP1 into a graph which is used to search for sequences of elements which are used in the XPath query XP2.

A Model for Psychosocial Phasing in CancerWe consider the problem of discovering candidate ID and IDREF attributes in a schemaless XML document. We characterize the complexity of the problem, propose a heuristic algorithm for it, and discuss experimental results.

N. J. C. Andreasen M.D., Ph.D.,A. S. Norrisroblems addressed and solved in this area are diverse. This diversity renders it difficult to know how the various results presented fit together, and even makes it hard to know what open problems remain. As a first step to rectifying this situation, we present a classification of the problem space

We study the impact of the schema transformations and query workload on the search strategies for finding efficie

In this paper, we introduce a virtual XML database engine VXE-R which allows users query a relational database via XML as if they were accessing XML documents. Algorithms for
