Persist extracted entities and link them with knowledge entries

[Pranavkale11]

Hi 👋
@JayeshWani7
The project extracts entities during AI processing, but they are not being stored or linked in the database.

Problem
Extracted entities are not saved in the entities table
No relationship is created between knowledge and entities
Entity-related endpoints may return empty or limited data

Impact
This limits the usefulness of entity-based exploration and reduces the value of extracted insights.

Suggested Fix
Store extracted entities in the database
Create links between entities and knowledge entries
Update API to return meaningful entity data

Expected Result
Entities are stored and tracked properly
Entity endpoints return useful data
Better navigation of knowledge through entities

Hi @JayeshWani7

I’d like to work on this issue as part of NSoC’26.
I have already worked on a related backend improvement (semantic search ranking fix), so I’m familiar with the codebase and ready to proceed with this implementation.

Could you please assign this issue to me and add the NSoC-26 label?

Thanks! 🙌

Hi @JayeshWani7, I would like to work on this issue (Persist extracted entities and link them with knowledge entries). I can implement the entity storage in DB, create links between entities and knowledge entries, and update the API. Please assign this issue to me if it's available.
