چکیده

This paper describes a prototype multilingual Q&A system that we have designed to participate in the Q&A Track of TREC-12. The system answer concrete responses, then we participate in the Q&A main task for factoid questions. The main areas of our system are: (1) Inductive Logic Programming to learn the question type, (2) Clustering of Named Entities to improve Information Retrieval and (3) Semantic relations and EuroWordNet synsets to perform a language-independent answer extraction.
