چکیده
This paper outlines the construction of a wine varietal classification engine. Through use of topic analysis, word stemming and filtering, a Näıve Bayes classification algorithm performed with a surprising degree of accuracy. This research, therefore, represents exciting first steps in applying Machine Learning techniques to an area not well studied in traditional research.

Predicting the composition of red wine blends using an array of multicomponent Peptide-based sensors.
Differential sensing using synthetic receptors as mimics of the mammalian senses of taste and smell is a powerful approach for the analysis of complex mixtures. Herein, we report on the effectiveness of a cross-reactive, supramolecular, peptide-based sensing array in differentiating and predicting the composition of red wine blends. Fifteen blends of Cabernet Sauvignon, Merlot and Cabernet Fran...
متن کاملPredicting wine ratings using linear models
In this paper I analyze reviews taken from a popular wine review website. I use linear regression to tune a model suited for predicting wine ratings. I compare a two models and select the best one with the best parameters using k fold cross validation. The results indicate that better predictions come from using more of the features, rather than less of them. This suggests that both the age of ...
متن کاملEco-Labeling Strategies: The Eco-Premium Puzzle in the Wine Industry
Eco-labeling signals that a product has been eco-certified. While there is increasing use of eco-labeling practices, there is still little understanding of the conditions under which eco-labels can command price premiums. In this paper, we argue that the certification of environmental practices by a third party should be analyzed as a strategy distinct from although related to the advertisement...

The concentrations of the rare earth elements (REE) in surface waters and sediments, when normalized on an elementby-element basis to one of several rock standards and plotted versus atomic number, yield curves that reveal their partitioning between different sediment fractions and the sources of those fractions, for example, between terrestrial-derived lithogenous debris and seawater-derived b...
