چکیده

This paper reports on Language Computer Corporation’s QA@CLEF 2007 preparation, participation and results. For this exercise, LCC integrated its open-domain PowerAnswer Question Answering system with its statistical Machine Translation engine. For 2007, LCC participated in the English-to-French and English-to-Portuguese crosslanguage tasks. The approach is that of intermediate translation, only processing English within the QA system regardless of the input or source languages. The output snippets were then mapped back into the source language documents for the final output of the system and submission. What follows is a description of the improved system and methodology and updates from QA@CLEF 2006.

The Negative Effect of Machine Translation on Cross-Lingual Question Answering

This paper presents a study of the negative effect of Machine Translation (MT) on the precision of Cross–Lingual Question Answering (CL–QA). For this research, a English–Spanish Question Answering (QA) system is used. Also, the sets of 200 official questions from CLEF 2004 and 2006 are used. The CL experimental evaluation using MT reveals that the precision of the system drops around 30% with r...
