3rd Open Challenge on Multilingual Question Answering over Linked Data
(QALD-3)

      http://www.sc.cit-ec.uni-bielefeld.de/ild

              collocated with CLEF 2013
        http://celct.fbk.eu/clef2013/index.php
--------------------------------------------------------------------------------



QALD-3 is the third in a series of evaluation campaigns on question
answering over linked data,
this time with a strong emphasis on multilinguality. In the context of a
half-day lab at
CLEF 2013, it offers two open challenges:

Task 1: Multilingual question answering
Task 2: Ontology lexicalization

All relevant information about training and test phase as well as the lab
can be found on the
website:

* Motivation & Scope *

While more and more semantic data is published on the Web, the question of
how typical Web users can
access this body of knowledge becomes of crucial importance. Over the past
years, there is a growing
amount of research on interaction paradigms that allow end users to profit
from the expressive power
of Semantic Web standards while at the same time hiding their complexity
behind an intuitive and
easy-to-use interface. Especially natural language interfaces have received
wide attention, as they
allow users to express arbitrarily complex information needs in an
intuitive fashion and, at least
in principle, in their own language. The key challenge lies in translating
the users' information
needs into a form such that they can be evaluated using standard Semantic
Web query processing and
inferencing techniques. To this end, systems have to deal with a
heterogeneous, distributed and very
large set of highly interconnected data. The availability of such an amount
of open and structured
data has no precedents in computer science and approaches that can deal
with the specific character
of linked data are urgently needed.

In addition, multilinguality has become an issue of major interest for the
Semantic Web community,
as both the number of actors creating and publishing data all in languages
other than English,
as well as the amount of users that access this data and speak native
languages other than English
is growing substantially. In order to achieve the goal that users from all
countries have access to
the same information, there is an impending need for systems that can help
in overcoming language
barriers by facilitating multilingual access to semantic data originally
produced for a different
culture and language.
