Issues related to missing attributes in aposteriori novelty assessments

Abstract

Novelty assessment is a fundamental activity for creativity evaluation of ideas or concepts. Accordingly, literature acknowledges a variety of suitable metrics, among which some "a-posteriori" versions are often used for assessing idea generated in experimental sessions. We observed that when in presence of tasks requiring multiple functions, the application of the metric becomes problematic. In this paper, we argue about the recalled issue, providing detailed suggestions for a correct "a-posteriori" novelty assessment of ideas generated from tasks with multiple required functions.
