Benchmarking Large Language Models for Detecting Satirical Code-Mixed Sentences

Read the original on arXiv Computation and Language →

The paper introduces CS‑SeLeRoSa, a synthetic dataset of over 600k code‑mixed Romanian sentences with English, German, French, and Italian, generated via four methods (random replacement, phrase translation, dependency parsing, and large language models). It evaluates multilingual large language models on satire detection in this dataset and a human‑annotated gold benchmark, CS‑SeLeRoSa‑Gold, showing that newer models like Gemma 4 31B outperform older open models and achieve competitive zero‑shot performance, with fine‑tuning further improving results.

PolERo: Studying Political Evasion in Romanian

PolERo presents a new dataset of 3,574 Romanian question‑answer pairs from presidential transcripts, annotated for political evasion using a two‑level taxonomy of response clarity and fine‑grained evasion strategies. The study evaluates various classification methods—including TF‑IDF baselines, fine‑tuned encoders, a sliding‑window encoder, and zero/few‑shot LLM prompting—under matched conditions. Cross‑lingual transfer experiments via joint bilingual training and machine‑translation augmentation reveal that fine‑tuned encoders perform competitively, transfer is asymmetric, and ambivalent evasion categories with pragmatic cues remain the most challenging across all models.

LuxIT: A Luxembourgish Instruction Tuning Dataset from Monolingual Seed Data

LuxIT is a monolingual instruction‑tuning dataset for Luxembourgish, created by synthesizing instruction‑answer pairs from native texts using the DeepSeek‑R1‑0528 model and a quality‑assurance LLM‑as‑judge process. The resulting 227,507 high‑quality pairs were used to fine‑tune 14 LLMs (≤15 B parameters), yielding an average accuracy increase of +5.37 percentage points on standardized Luxembourgish proficiency exams and improvements in macro‑averaged F1 on nine of the fourteen downstream NLP tasks. These findings demonstrate that synthetic monolingual data can effectively enhance LLM performance in low‑resource languages and reveal the complex relationship between exam performance and practical NLP gains.
