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.
