Abstract

Retrieval-augmented generation (RAG) has been used to improve the accuracy and transparency of outputs produced by large language models (LLMs) by integrating external knowledge; however, applying RAG to lowresource languages presents unique challenges, including poor embedding representations, low retrieval quality, and semantic gaps caused by the scarcity of digital documents.In this research, we address these challenges for a selected low-resource language, Amharic, by using translative and debate-based RAG techniques to improve retrieval and reasoning.This paper outlines the key problems and research gaps in applying RAG to low-resource languages and introduces a method to enhance RAG performance for Amharic.Additionally, we introduce the first comprehensive Amharic Retrieval-Augmented Generation Benchmark (ARGB), designed to capture grammatical, cultural, and writing-system-specific constraints of the Amharic language.ARGB evaluates not only retrieval and generation quality, but also noise robustness, counterfactual robustness, negative rejection, and multi-source information integration, providing a holistic assessment of RAG capabilities.The dataset, which spans a wide range of categories, is evaluated using multiple evaluation metrics.Furthermore, we demonstrate that, using our dataset, translation-based and debate-based methods substantially improve various aspects of RAG pipeline assessment in the Amharic language.This work aims to improve the reliability, accessibility, and inclusiveness of AI systems for Amharic speakers while providing a scalable framework for other low-resource languages.Current progress on the code and benchmark can be found on this GitHub link: link.

TL;DR

This paper adapts translative RAG and multi-agent debate to Amharic, translating Amharic queries/contexts into English for reasoning and using Proponent/Challenger/Judge agents to refine retrieval and answers. It also introduces ARGB, an Amharic RAG benchmark, and reports accuracy gains from 25.0% for native Llama 3.2 Amharic to 32.0% with translation plus debate.

Key findings

  • The proposed translation-and-debate method reached 32.0% accuracy, versus 29.0% for translation-based Llama 3.2, 25.0% for native Llama 3.2 Amharic, and 22.0% for native Walia-LLM; this is a 17% relative improvement over the strongest native baseline.
  • Robustness results showed the proposed method had the highest Negative Rejection Rate at 0.043, compared with 0.042 for translation-only, 0.035 for native Llama 3.2 Amharic, and 0.030 for Walia-LLM; Error Correction Rate was 0.020 for the proposed method, 0.021 for translation-only, 0.007 for native Llama 3.2 Amharic, and 0.010 for Walia-LLM.
  • ARGB is presented as the first comprehensive Amharic RAG benchmark, built from the Amharic Wikipedia dump with 40 articles, 450 chunks, and 200 total entries: 100 direct QA, 20 noise robustness, 20 negative rejection, 20 information integration, and 20 counterfactual.
  • Qualitative analysis suggests debate-based RAG excels at correcting definitive factual inaccuracies but remains constrained when retrieved Amharic contexts are sparse or contradictory.

Methods

  • Translative RAG: the Amharic query and retrieved Amharic contexts are translated into English, the high-resource LLM reasons and synthesizes in English, and the final answer is translated back into Amharic.
  • Debate-enhanced RAG: retrieval debate iteratively refines queries and retrieved passages; response debate cross-examines candidate answers. Agents are assigned Proponent, Challenger, and Judge roles. Models used are Walia-LLM and Llama-3.2-Amharic, with xlm-roberta-base-finetuned-amharic embeddings and decoding at temperature 0.3, top_p 0.8, top_k 8, repetition penalty 1.05, and max_new_tokens 128.
  • Benchmark and evaluation: ARGB uses Amharic Wikipedia main pages of at least 2 KB, cleaned and chunked into non-overlapping five-sentence segments; fact-based QA pairs cover number, text, and date types across 15 domains. Evaluation uses exact-match Accuracy, Negative Rejection Rate, and Error Correction Rate.

Limitations

  • Stated: translation-based generation may propagate biases from high-resource models; retrieval-augmented systems may reproduce inaccuracies or culturally sensitive source content; debate improves factual grounding but does not eliminate hallucinations or bias; dataset construction may reflect implicit cultural or topical biases and limit representativeness.
  • Stated: performance remains constrained in high semantic ambiguity where retrieved Amharic contexts are sparse or contradictory; Error Correction Rate plateaued at 0.020; the translative debate pipeline incurs higher latency and cost; English reasoning may introduce Western assumptions misaligned with Ethiopian cultural or regulatory contexts.
  • Evident from the text: the benchmark is small at 40 articles and 200 entries and is skewed toward history because the source Amharic Wikipedia corpus is predominantly historical; only two Amharic LLMs are evaluated, and no statistical significance testing is reported.

  • Classified as probably not a substantial claim.

    Study design and conductnone given

    The ground-truth answers in the benchmark have been curated to account for various linguistic permutations and formatting possibilities that represent a correct answer.

    “To ensure a robust and fair evaluation, the ground-truth answers in the benchmark have been curated to account for various linguistic permutations and formatting possibilities that represent a correct answer, ensuring that valid semantic variations are accurately captured during the verification process.”

    Study design and conductown data

    To test negative rejection, the benchmark intentionally fetches queries from external datasets whose answers do not exist within the Amharic Wikipedia dump.

    Adaptation of RAG to low-resource languages remains insufficiently studied.

    “Despite its demonstrated success in high-resource contexts, the adaptation of RAG to low-resource languages remains insufficiently studied.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Counterfactual robustness has opposing success criteria

    Major

    One definition calls for following deliberately falsified retrieved context over the model's prior knowledge; the evaluation definition instead calls for detecting errors in that context and producing the correct answer.

  • Dataset category counts do not sum to the reported total

    Minor

    The listed categories contain 100 direct QA entries and four groups of 20, totaling 180 rather than 200.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-07.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-07.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
