Problems retrieving info from knowledge source

Hi everyone,

I've created an academic tutor agent designed to help students with their assignments. The main knowledge source for this agent is a large (1000 page) pdf of a social studies textbook. It's important that the agent only refer to the content of the textbook when answering student's questions and that it not use other soruces (including web and "general knowledge").

The trouble is, when I shut off, "Use general knowledge" and "Use information from web" in the settings, the agent frequently gives the following error in response to queries: “no information was found that could help answer this," despite the fact that the relevant information is present in the textbook.

I was troubleshooting with Copilot and it suggested the following:

1. Verify the pdf is actually text (possible OCR issue). I checked and I CAN select, copy, and paste text from the textbook, so I don't think that's the issue.

2. Consider breaking the pdf into smaller chunks (30 to 80 pages) with clear headers, section titles, and a consistent structure -> I haven't tried this, yet.

Is there anything else I should consider doing to fix this problem?

How did you add the PDF?

Is it uploaded or hosted on SharePoint?

Have you checked the activity to see if this landed on any topic?

Usually what I do is go to the fallback topic and point the knowledge there also.

@CU04022132-0 Thanks for your reply.

I uploaded the file. It proccessed, and the status is "ready."

Regarding your topic question: I'm a newb with this, so bear with me - In the "test your agent" section, I clicked on the "I'm sorry, I'm not sure how to help with that" response I got.

That opened the topic window I think? It shows a flow of events starting with "Trigger" and moves downward to other events including, "condition," "all other conditions," "topic..." (see attachment "fallback").

Is this the "fallback topic" you're referring to?

Hi,

Just try to figure out if your issue is with the PDF (reference document) or your settings.
First, leave all of your settings the same and change the reference document to a much simple one, like a 2 page document, with very simple Q&A.
then ask the agent a question. If you get the correct response, then it may be from your Knowledge source.

You could try to break the pdf into smaller chunks. But another thing to consider is the type of context that is in the 1000 page pdf.

Being a social studies textbook, does it contain things like war, crime or any sensitive topics that might get flagged as sensitive or harmful?

Let me know how it goes.
