Optimizing Query Answering under Ontological Constraints

Optimizing Query Answering under Ontological Constraints

Show other versions (1)

Ontological queries are evaluated against a database combined with ontological constraints. Answering such queries is a challenging new problem for database research. For many ontological modelling languages, query answering can be solved via query rewriting: given a conjunctive query and an ontolog...
