Abstract
Computational neural network methods are increasingly being used for researchoriented
data mining tasks. Kohonen self-organising map (SOM) techniques are
well established within the so-called connectionist paradigm of Artificial
Intelligence where neural networks are used to extract both explicit and implicit
dependency values often between data that is sometimes disparate in type and
kind. The research described here seeks to elicit relationships between grape
varieties and their growing conditions using SOM techniques. In addition,
utilising k-means and principle component analysis (PCA) methods, the data
mined and depicted by the SOM technique is shown to have dependency values
that enable a clustering of terms relating to variety quality to be associated with
growing condition data to produce optimal locations for each. This study is part
of a larger research project that uses comparative data from New Zealand and
Chile. The text mining aspect of it forms one element of a ‘toolbox’ of integrated
hardware and software instruments being developed to underpin an
environmental modelling methodology oriented not only towards grape growing
but also generally for optimal crop production. The example described here uses
data from New Zealand in the first instance. The paper begins with a summary
of some historical wisdom relating to grape growing with a discussion of some
previous studies and then describes the text mining of comments from wine
tasters, which are statistically analysed. The results are clustered and the paper
concludes with a reflection on the investigation with a pointer to future work in
this aspect of the larger research project previously described.
Keywords: text mining, wine taster comments and wine sensory data.
