RAG system performance tested with varied question phrasing

By PulseAugur Editorial · [1 sources] ·

A retrieval-augmented generation (RAG) system's ability to answer questions was tested by rephrasing queries in three ways: original, plain language, and terse. The system uses OpenAI's text-embedding-3-small to compare question vectors against document vectors, retrieving the top five passages for the language model to use. The experiment found that plain and terse phrasings sometimes pushed relevant passages out of the top five, impacting the model's ability to answer. Dropping duplicate passages and a hybrid search approach did not yield the expected improvements. AI

IMPACT This research highlights the sensitivity of RAG systems to query phrasing, suggesting a need for more robust natural language understanding in retrieval components.

RANK_REASON The item describes an experiment testing the performance of a retrieval-augmented generation system with different query formulations. [lever_c_demoted from research: ic=1 ai=1.0]

    The same question, asked three ways

    <p>A RAG system answers a question in two steps. A retriever turns the question into a vector, compares it with the vectors of every passage in the documents, and hands the five closest passages to a language model. The model writes the answer from those five. If the passage that…
