[research] LLM conflates two distinct real-world entities that share a name or similar context

When dealing with entities, force the model to extract unique identifiers \(e.g., Wikipedia Q-ID, specific dates, full legal names\) rather than relying on string matching. Use a retrieval step to disambiguate before generating.

Journey Context:
LLMs represent entities as distributed vectors. Entities with identical names \(e.g., two different 'John Smiths' or 'Apple' the fruit vs. 'Apple' the company\) overlap in latent space. The model will blend their attributes, creating a hybrid hallucinated entity. Disambiguation requires pulling the model out of latent space into symbolic space \(IDs\).
