Ontologies and Logic Programming for Query Answering

This international workshop is affiliated with 
the 24th International Joint Conference on 
Artificial Intelligence (IJCAI-2015, 
http://ijcai-15.org) and will take place in 
Buenos Aires, Argentina, July , 2015.

Workshop description
The aim of this workshop is to bridge knowledge 
representation and reasoning in artificial 
intelligence and web of knowledge communities in 
order to encourage the emergence of new solutions 
for reasoning with lightweight ontologies.
Query answering while taking ontologies into account.
Non monotonic reasoning for inconsistency 
handling and exception handling and expressing default negations in ontologies.

Concerning the first point, a challenging issue 
is how to adapt or extend Answer Set Programming 
to represent ontological knowledge. In 
particular, can (a fragment of) ASP cover 
lightweight ontological languages while keeping decidability and efficiency?

Concerning the second point, a challenging issue 
is how to extend lightweight ontological 
languages with non-monotonic features, while 
keeping a good computational complexity. In particular,
how to embed exceptions-based and inconsistency 
tolerant-based reasoning in a tractable ontological language?
how to integrate uncertainty information in lightweight ontological languages?
how to define merging operations where both 
inputs and outputs are in lightweight ontological languages?

Topics of interest include but are not limited to:
Reasoning with lightweight ontologies
Reasoning with tractable fragments of OWL languages
Belief change & tractable Description logics
Reasoning on the web of data
Ontology-based data-access
Ontological query answering
Belief change & ASP
Datalog+/- & existential rules
ASP & description logics
ASP & uncertainty
First-order ASP

The workshop is expected to bring together people from different
research communities that are actively pursuing this line of

Paper submission
The authors should submit their paper via EasyChair:

We expect submissions of both mature and 
preliminary works. Long papers will not exeed 8 
pages and short papers will not exceed 4 pages in 
pdf formatted using the AAAI style according to the instructions at

After the workshop, the authors of accepted 
papers will be invited to submit an extended 
version for inclusion in a special issue of the 
Annals of Mathematics and Artificial Intelligence 
(AMAI) journal published by Springer.
