The paper introduces SAFE‑QE, a training‑free, retriever‑agnostic method for query expansion that mitigates hallucinated terms from large language models. It uses a subsequence‑association filter to score candidate terms based on their reproducibility across randomised query contexts, down‑weighting terms that lack corpus support. SAFE‑QE then selects a broad yet consistent set of expansions via constrained coverage maximisation, and defines a new metric, the Hallucinated Expansion Term Rate, to quantify faithfulness. The approach matches state‑of‑the‑art ranking performance while injecting far fewer unsupported terms on TREC and BEIR benchmarks.

The paper presents a curated German–English parallel corpus derived from OPUS Books, reduced from 45,000 raw sentence pairs to 25,000 high‑quality examples through filtering and quality scoring. It details a reproducible fine‑tuning process for Meta’s NLLB‑200 models using mixed precision and gradient techniques, yielding a fine‑tuned NLLB‑600M model that improves BLEU, chrF++, and TER scores on literary and technical translations. The authors also integrate the model into the LinguaHaru translation system, enabling format‑preserving translation of PDFs and Office documents, and release all scripts, code, and the model on HuggingFace.

Recent advances in Large Language Models (LLMs) have demonstrated strong capabilities in generating semantically relevant concepts and relations, making them promising tools for taxonomy enrichment. However, directly relying on LLM-generated expansions often leads to noisy, redundant, or hierarchically inconsistent structures, limiting their reliability for automated taxonomy expansion.
