Cross Lingual Abstractive Summarization for Marathi

The paper presents a cross‑lingual abstractive summarization system for Marathi, leveraging the Marathi MahaSum corpus and the smaller PMIndiaSum dataset to fine‑tune the IndicTrans2 neural machine translation model. Evaluation on Marathi‑to‑English summarization using ROUGE, chrF, and chrF++ metrics shows that this approach outperforms prior IndicBART and mBART‑50 baselines. The authors also discuss extending the method to English‑to‑Marathi summarization.

COILD: An Indic-Centric Parallel Corpus and Benchmark for Machine Translation Across Indian Languages

COILD is an Indic‑centric parallel corpus that contains over 1.16 million human‑translated and verified sentence pairs across 20 Indian language pairs from four language families. The corpus is sourced from original Indian language materials in eight domains, and a 2,000‑sentence domain‑centric benchmark is provided for consistent multilingual evaluation. Experiments with IndicTrans2‑Distilled and NLLB‑200 show consistent improvements in automatic metrics and human judgments, underscoring the value of high‑quality Indic‑centric data.

Can Classical Semantic-Extractive Summarization Be Evaluated in Hindi? A Replication Study

The study replicates a distributional‑semantics extractive summarisation method for Hindi, adapting all language‑specific components to Devanagari. Evaluated on the Hindi portions of XL‑Sum and FIRE ILSUM 2.0 with a Devanagari‑aware ROUGE scorer, the replicated system performs significantly worse than a simple three‑sentence lead baseline. Feature ablation shows that sentence position alone reproduces the lead baseline, while other features only steer extraction toward long, entity‑dense body sentences, and TextRank performs identically. "whyItMatters":"The results indicate that current Hindi summarisation benchmarks cannot reward non‑lead content selection, highlighting the need for purpose‑built evaluation resources."

Evaluating Large Language Models for Multilingual Abstractive Summarization: A Comprehensive Study of English and Bengali

The study introduces a zero‑shot benchmark for eight large language models on English and Bengali abstractive summarization, using both lexical/semantic metrics and reference‑free factuality checks. Results show significant cross‑lingual differences: GPT‑5.6 Luna excels in English but not in Bengali, where LLaMA 3.3 70B tops ROUGE and BLEU, while Gemini 2.5 Flash achieves the best Bengali factuality score. The evaluation also reveals that different metrics rank models differently, underscoring the need for multi‑dimensional assessment in low‑resource languages.
