[research] LLM conflates two different entities that share the same or similar names

When generating information about an entity, require the agent to pull disambiguation context \(e.g., industry, location, founding date\) and explicitly state which entity it is referring to before providing details.

Journey Context:
LLMs represent entities as distributed vectors, meaning similar names share overlapping weights. This leads to 'entity hallucination' where the model blends facts about two distinct entities. By forcing the model to ground the specific entity instance via unique identifiers or disambiguating attributes first, you prevent the vector space overlap from polluting the factual generation.
