Title Towards Empirical Evaluation of Affective Tactical NLG
Venue European Workshop on Natural Language Generation
Year 2009

One major aim of research in affective nat- ural language generation is to be able to use language intelligently to induce effects on the emotions of the reader/ hearer. Al- though varying the content of generated language (“strategic” choices) might be expected to change the effect on emotions, it is not obvious that varying the form of the language (“tactical” choices) can do this. Indeed, previous experiments have been unable to show emotional effects of tactical variations. Building on what has been discovered in previous experiments, we present a new experiment which does demonstrate such effects. This represents an important step towards the empirical evaluation of affective NLG systems.
