This paper reports on Language Computer Corporation’s first QA@CLEF participation. For this exercise, LCC integrated its open-domain PowerAnswer Question Answering system with its statistical Machine Translation engine. For 2006, LCC participated in the English-to-Spanish, French and Portuguese cross-language 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 system and methodology.
