BordaRAG: Elevating Generative AI Accuracy Through Conflict-Aware Document Selection
Traditional Retrieval-Augmented Generation (RAG) systems often falter when retrieved documents present conflicting information, leading Large Language Models (LLMs) to generate unreliable outputs. Our analysis of BordaRAG reveals a novel, preference-based voting mechanism that intelligently sifts through contradictory knowledge, ensuring LLMs receive the most coherent and accurate context, dramatically boosting response quality.
Executive Summary: Key Performance Enhancements
BordaRAG addresses a critical vulnerability in RAG systems by moving beyond simple majority voting. By leveraging Borda Voting, it evaluates the global preference of information sources, resulting in a more robust selection of supporting evidence for LLMs, even amidst significant knowledge conflict.

Understanding Knowledge Conflict in RAG
Retrieval-Augmented Generation (RAG) enriches Large Language Models (LLMs) with external knowledge, but this often introduces conflicting information from diverse sources. Existing solutions, primarily relying on simple majority voting, frequently fail in complex scenarios where the most popular answer isn't necessarily the correct one, leading to inaccurate LLM outputs.

Constructing a Robust Preference Matrix
BordaRAG's first critical step is to accurately gauge each retrieved document's preference for various candidate answers. This involves prompting LLMs to generate initial answers per document, deduplicating them to form a candidate set, and then evaluating the 'preference degree' of each document for every candidate. This creates a detailed preference matrix, moving beyond binary support to continuous scores.

Aggregating Preferences with Borda Voting
Unlike Majority Voting, which only considers a voter's top choice, Borda Voting aggregates preferences by assigning scores based on the full ranking of candidates. This allows BordaRAG to select the candidate answer with the highest collective support, even if it's not the most frequently mentioned. The winning answer then guides the selection of the most relevant documents for the final LLM generation.
| Feature | Borda Voting (BordaRAG) | Majority Voting (Traditional) |
|---|---|---|
| Preference Consideration | Considers full ranking order of candidates, assigning points based on position. | Only considers the top-ranked choice of each voter. |
| Score System | Continuous, preference-based scores (e.g., from LLM probabilities or ranks). | Binary (vote/no vote) or simple frequency count. |
| Conflict Resolution | More robust in diverse candidate pools; less susceptible to vote splitting and minority suppression. | Ineffective with many diverse candidates or when popular answer is incorrect. |
| Effectiveness with Conflict | Highly Effective: Designed for scenarios with high knowledge conflict. | Limited Effectiveness: Struggles when the majority view is wrong or highly nuanced. |
| Output Selection | Selects candidates that best represent the collective viewpoint. | Selects the most frequently mentioned candidate, which may be biased or incorrect. |
Proving BordaRAG's Superiority
Our theoretical analysis formally demonstrates BordaRAG's robustness. We prove that the expected distortion of Majority Voting (MV) grows super-constantly with an increasing number of candidate answers, indicating its rapid decline in reliability under diverse information. In stark contrast, Borda Voting (BV) maintains a constant upper bound on distortion, confirming its superior stability and accuracy in complex, conflicting RAG environments.

Real-World Performance and Case Studies
BordaRAG's effectiveness is validated across three open-domain QA datasets (NQ, PopQA, TriviaQA) and three leading LLMs, consistently outperforming all baselines. Notably, its gains are most significant in high-conflict scenarios (e.g., NQ), precisely where traditional methods falter. A compelling case study illustrates how BordaRAG correctly identifies the true answer where majority voting methods succumb to misinformation.
Case Study: Resolving Misinformation
Consider the query "rosie and the originals angel baby release date?". In a scenario where retrieved documents present conflicting information, a simple majority vote might incorrectly identify "1964" as the answer (supported by 4 documents), despite it being a hallucination. BordaRAG, by contrast, considers the full preference landscape and correctly identifies "1960" (supported by only 2 documents but strongly preferred by others) as the correct answer. This highlights BordaRAG's ability to discern truth amidst popular falsehoods.
