Maybe you have a table with all your customers, for each . Introduction to Classification. Mirkin B: Mathematical Classification and Clustering. It may disappoint you but there is no text understanding and very little semantic analysis in place. Researchers have noted that people find it a natural task.

It is the art of finding groups in data and relies on the meaningful interpretation of the researcher or classifier [16].

The stated problem is quite difficult, in particular for microarrays, since the inferred prediction must be Kaufman L, Rousseeuw PJ: Finding Groups in Data: An Introduction to Cluster Analysis.
