Traditional approaches to query processing aim at
rewriting a given query into another more efficient one
that uses less time and/or resources during the execution.
There by, the rewritten query must be equivalent to
the initial one, i.e., it must provide the same result. However,
rewriting queries in equivalent ways do not always
satisfy the user’s needs, in particular when the user
does not receive any answer at all. In this paper we propose
a new approach for query processing which allows
to rewrite a query into another one which is not necessary
equivalent but can provide more meaningful result satisfying
the user’s intention. For this purpose, we illustrate
how semantic knowledge in form of ontologies could be effectively
used. We develop a set of rewriting rules which
rely on semantic information extracted form the ontology
associated with the database. In addition, we discuss
features of the necessary mappings between the ontology
and its underlying database.
