In this project note, we present the main features of lex- icalisation strategies deployed by humans in question- answering (QA) tasks. We then show how these can be reproduced in automated QA systems, in particular in In- telligent Cooperative Question-Answering Systems. 1 Motivations The framework of Advanced Question Answering (QA) systems, including cooperative QA answer- ing, as described in a recent road map (Voorees 2003), raises new challenges for language gener- ation since answers are often produced via dedi- cated inference mechanisms operating over various knowledge sources, including conceptual ontolo- gies. Producing well-formed and informative re- sponses gives a whole new insight to language gen- eration, and in particular to the difficult problem of lexicalisation. For exa...
