Multiple Concepts per Category, but One Concept per Document
Note when collecting a set of documents for categorization analytics in Relativity while the group of documents may represent different aspects of a category, you should try to find individual documents that focus on a single concept. So while there can be one category for fraudulent communications and fraudulent accounting, each document should only discuss one concept. The individual document should fully explain the concept. Using a document that only addresses the concept in a few sentences is not sufficient.
The example documents in a categorization set should also not have sections of bad OCR or irrelevant footers.
