There are well established methods for fuzzy clustering especially for the cases where the
feature values are numerical of ratio or interval scale. Not so well established are methods to
be applied when the feature values are ordinal or nominal. In that case there is no
satisfactory method it seems. This paper discusses a modified fuzzy c-means clustering
method where an ordinal to numeric mapping for the ordinal features is obtained as part of
the clustering process. Part of minimizing the objective function for the clustering is to find …
