Study of the polysemic term of minerality in wine: Segmentation of consumers based on their textual responses to an open-ended survey
International audience; Over the past 20 years, the word "minerality" has been increasingly used in the description of wines. However, a precise definition of the concept of minerality appears to be inexistent, and no consensual meaning, even among wine professionals, can be identified. Although this word usage seems to spread out from wine professionals to consumers, research on what consumers assume about minerality is scarce. This paper aims to study the various concepts about minerality held-by consumers by using an open-ended questionnaire.A total of 1697 French-speaking consumers responded to an, online survey and their free answers were analysed using statistical textual methods.

Clustering of textual networks: analysing open-ended questions in text data of the perception of minerality in wine
International audience; Open-ended questions are commonly used in sensory analyses, and are usually dealt with by correspondence analysis (CA) of the term-respondent matrix. CA is apt in detecting strong associations between terms and groups of respondents, but less so when the questions are interpreted differently among respondents and, thus, seem to open a polysemic space for the answers. Also, CA offers little flexibility in filtering out irrelevant textual structure, or in controlling the relative contribution of rare versus frequent terms in the overall analysis. This contribution presents methodological extensions of CA together with application on a survey of 1900 responses bearing u…
