TITLE: Exchanging OWL 2 QL Knowledge Bases
SPEAKER: Vladislav Ryzhikov, Free University of Bolzano

ABSTRACT: The problem of exchanging knowledge between a source and a target
knowledge base connected through a mapping has attracted attention recently
both in databases and in knowledge representation. We study this fundamental
problem for knowledge bases and mappings expressed in the description logic
DL-LiteR, which is the formal counterpart of OWL 2 QL. We consider several
notions of solutions, i.e., materializtions, that preserve at best the meaning of
source knowledge with respect to the mappings. We present the complexity
results for the problems associated with computing of the solutions.
