[research] Hallucinating facts about an entity based on superficial name similarity to a more popular entity

Disambiguate entities explicitly before generating facts. Use a knowledge base lookup \(like Wikidata\) to resolve the exact entity ID, then condition generation on the retrieved entity profile.

Journey Context:
If a user asks about 'Apple Corp' \(the Beatles' company\), the model might output facts about Apple Inc. because of token co-occurrence in the training data. LLMs rely on superficial correlations rather than deep entity identity. RAG based purely on string matching exacerbates this. Entity linking/resolution must happen \*before\* generation to anchor the model to the correct factual silo.
