A Method for Evaluating Full-text Search Queries in Native XML Databases
In this paper we consider the problem of efficiently producing results for full-text keyword search queries over XML documents. We describe full-text search query semantics and pr...

Probabilistic Ranking of Database Query Results
We investigate the problem of ranking answers to a database query when many tuples are returned. We adapt and apply principles of probabilistic models from Information Retrieval f...

On probabilistic fixpoint and Markov chain query languages
We study highly expressive query languages such as datalog, fixpoint, and while-languages on probabilistic databases. We generalize these languages such that computation steps (e....

Efficient Database-Driven Evaluation of Security Clearance for Federated Access Control of Dynamic XML Documents
Achieving data security over cooperating web services is becoming a reality, but existing XML access control architectures do not consider this federated service computing. In this...
