So since this is a more serious inquiry than I thought, and everything I've shared is observational for now. Here's my thinking:
1. Take a baseline of the article today. Categorize the citations and sources.
2. Start tracking changes on the page you care about. A free version of visualping alerts should do just fine.
3. When you get the email alerts, start categorizing the change mentioned in see edits to gather data.
4. You now have a baseline, dates where changes are made, and the types of changes and sources added on one article.
Repeat 1-4 with a few other entities your client wants you to do work on. Maybe an ideal listing, a competitor's listing, etc. Teach this to someone junior after the workflow is done and/or create an agent for bonus points if orchestrating an agent team is more of your thing.
Correlation here is good enough as long as the goal is to work on core ORM activities with an understanding that there is a probability it is correlated to changes in Grokipedia.
