IMPORTANT PRACTICAL ASPECTS OF AN OPEN-DOMAIN QA SYSTEM PROTOTYPING

This paper deals with several practical aspects of an open-domain QA system implementation. Specifically, we describe the process of the query formulation from the question analysis as well as the identification and the ordering of the text snippets that may contain the sought answer in the context of the CLEF 2008 Romanian-Romanian QA track. We show that the tuning of these system components is important with respect to the output of the QA system and will directly affect the performance measures.
