Workshop on
Multilingual Question Answering - MLQA'06

April 4, 2006, Trento, Italy

The EACL 2006 Workshop on Multilingual Question Answering will be hosted in conjunction with the 11th Conference of the European Chapter of the Association for Computational Linguistics which will take place April 3-7, 2006, in Trento, Italy.


Despite the great deal of attention that Question Answering (QA) has received in recent years due to the landmark Q&A Track at the Text REtrieval Conference (TREC), multilinguality has been outside the mainstream of QA research, which has focused mainly on the English language. Multilingual QA has emerged only in the last few years as a complementary research task, representing a promising direction for at least two reasons. First, it allows users to interact with machines in their native languages, contributing to easier, faster, and more equal information access. Second, cross-lingual capabilities enable QA systems to access information stored only in language-specific text collections.

The success of the QA track in recent evaluation campaigns at CLEF (Cross-Language Evaluation Forum) and NTCIR (Evaluation of Information Access Technologies) has shown increasing interest in both monolingual non-English QA (questions and answers in the same language) and in cross-lingual QA, where the question is posed in a source language and the answer must be found in a target collection of a different language.

The workshop intends to address a number of challenging issues for research in multilingual QA, including searching in multilingual document collections, collecting and merging answers found in documents from different languages, using heterogeneous multilingual data collections (such as the Web, XML data or data in relational databases) for answer generation, and interpreting questions in different languages. Additionally papers related to user studies or case studies where multilingual QA has played a major role are most welcome.


Relevant topics for the workshop include but are not restricted to:

  • Monolingual QA systems for languages other than English;
  • Cross-lingual QA systems;
  • Multilingual Web-based QA;
  • Case studies and user studies of Multilingual QA;
  • Specific Translation techniques for Cross-lingual QA;
  • The influence of translation on Cross-lingual QA;
  • Multilingual QA in restricted vs. open domains;
  • QA from heterogeneous multilingual data collections such as unstructured text, semi-structured data and structured data;
  • Techniques for porting QA systems among languages;
  • The effectiveness of particular techniques in different languages;
  • Comparisons between QA in different languages including European and Asian languages;
  • Evaluation of Multilingual QA systems;
  • Resources for Multilingual QA.
