Fig. 4.4.10 Map reduce can be used to address text.

MapReduce is a language for the technician that can be used to do all sorts of useful
things in big data. However, the number of lines of code that must be written and
maintained and the sheer complexity of contextualizing nonrepetitive unstructured data
limits the usefulness of MapReduce for the purpose of contextualizing nonrepetitive
unstructured data.

There is one other time-honored approach to analyzing nonrepetitive unstructured data.
That approach is to do things manually. Fig. 4.4.11 shows that nonrepetitive unstructured
data can be analyzed manually.
