[research] Entity Disambiguation Failure in Retrieval

Implement entity linking or query expansion before retrieval. Use the LLM to extract core entities from the query and append disambiguating context \(e.g., Apple the company\) before passing it to the vector database.

Journey Context:
Dense vector embeddings often conflate polysemous words because their nearest neighbors in vector space overlap. Standard RAG pipelines treat the query as a monolith, leading to context contamination. By forcing the LLM to perform explicit entity resolution first, the retrieval precision increases dramatically, at the cost of an extra LLM call per query.
