Understanding normalization
Normalization is a process that converts a list of words to a more uniform sequence. This is useful in preparing text for later processing. By transforming the words to a standard format, other operations are able to work with the data and will not have to deal with issues that might compromise the process. For example, converting all words to lowercase will simplify the searching process.
The normalization process can improve text matching. For example, there are several ways that the term "modem router" can be expressed, such as modem and router, modem & router, modem/router, and modem-router. By normalizing these words to the common form, it makes it easier to supply the right information to a shopper.

Normalization operations can include the following:
- Changing characters...
