Nathalie Rose Lim, Patrick Saint‐Dizier, Rachel Edita Roxas · 2009
Comparative and evaluative question answering (QA) requires a detailed semantic analysis of comparative expressions and complex processing. Semantics of predicates from questions have to be translated to quantifiable criteria before extraction of information can be done. This paper presents some challenges faced in answering comparative and evaluative questions. An application on the domain of business intelligence is discussed.
