find. It is noted that context is in fact there in the nonrepetitive big data environment; it
just is not easy to find and is anything but obvious.

In order to find context, the technology of textual disambiguation is needed. Textual
disambiguation reads the nonrepetitive data in big data and derives context from the data.
(See the chapter on textual disambiguation and taxonomies for a more complete
discussion of deriving context from nonrepetitive raw big data.)

While most of the nonrepetitive raw big data is useful, some percentage of data are not
useful and are edited out by the process of textual disambiguation.

Once the context is derived, the output can then be sent to either the existing system
environment.

Fig. 8.2.3 shows the interface from nonrepetitive raw big data to textual disambiguation.
