-------------------------------------------------------------------


During the recent decade, handling uncertainty and vagueness has
started to play an important role in ontology languages, especially
in application areas like the Semantic Web, Biomedicine, and
Artificial Intelligence. For this reason, there is currently a strong
research interest in Description Logics (DLs) that allow for dealing
with uncertainty. The subject of this workshop is how to deal with
uncertainty and imprecision in DLs. This encompasses approaches that
enable probabilistic, fuzzy or rough reasoning in DLs.  Other
approaches to model and reason with uncertainty formalisms are of
interest to UniDL as well.

The workshop focuses on the investigation of reasoning problems and
approaches for solving them -- especially tractable ones. For
classical DL reasoning problems such as subsumption and
satisfiability, algorithms that can handle uncertainty exist, but
they are not yet as well-investigated as for DLs without uncertainty.
For novel DL reasoning services, such as query answering, computation
of generalizations, computation of modules, or explanations, it is
not yet clear how to realize them in DLs that can express
uncertainty. The workshop is dedicated to discuss such issues.


SPONSOR

UniDL is sponsored by the Artificial Intelligence Journal (AIJ).

IMPORTANT DATES:

       Submission deadline: ***May 7, 2012***
              Notification: June 1, 2012
             Final version: June 8, 2012
                  Workshop: June 30, 2012


SUBMISSION DETAILS:

The workshop welcomes submissions in pdf format in Springer's LNCS
style. Submissions can be
- technical papers not exceeding 10 pages,
- system descriptions not exceeding 6 pages, or
- position papers on work in progress not exceeding 3 pages
in LNCS. Submissions are via EasyChair at
http://www.easychair.org/conferences/?conf=unidl12  .
The workshop proceedings will be published as CEUR proceedings.

We adopt the same double submission policy as the DL workshop; that
is, we welcome submissions of papers that have recently published at
other conferences (e.g., KR, AAAI, etc).
