Development of a method to evaluate odour quality based on non-expert analysis

Résumé

Characterizing odour quality is a complex process that consists in identifying a set of descriptors that best synthesizes the olfactory perception. Generally, this characterization results in a limited set of descriptors provided by professionals in sensorial analysis. These experts previously learnt a common language to describe characteristic odour (Odour wheel or Champ des odeurs ©). These sensorial analysis sessions cost industrial manufacturers large sums every year. If this characterization is entrusted to neophytes, the number of participants of a sensorial analysis session can be significantly enlarged while reducing costs. However, each individual description is no more related to a set of non-ambiguous descriptors but to a bag of terms in natural language. Two issues are then related to odour characterization. The first one is how translating free natural language descriptions into structured descriptors; the second one is how summarizing a set of individual characterizations into a consistent and synthetic unique characterization for professional purposes. This paper will propose an approach based on natural language Processing and Knowledge Representation based techniques to formalize and automatize both translation of bags of terms into sets of descriptors and summarization of sets of structured descriptors.
