Once you have collected your representative document samples and have performed an initial analysis of their contents, you may want to categorize them further. The categorization process can help you to define the top-level topics and children contained in your topic design, and help determine the operators and weights to assign.
Following are categorization examples:
Geographic location
Sit
Project
Subject area
Date
The categorization process can help you understand the common, meaningful elements which exist in your information sources. For example, if you categorize your information by date (such as a month), it makes sense to create topics that use relational operators, such as EQUALS.
