Using metadata for enhanced corpus analysis
Metadata simplifies the task of finding important parts of a corpus. Identifying the fundamental concepts of a document and saving these insights will make our research more valuable and save us time.
There are at least three ways to use metadata:
Find a document corresponding to a key decision.
Filter or subset a group of documents for further analysis.
Sort by importance or frequency.
Note: Identify sections as FIND, FILTER, and SORT.
