Padàrtha is the first ontology‑grounded fine‑grained Named Entity Recognition benchmark for Classical Sanskrit, built on the Mahêbhárata epic. Its tag set, derived from the Nyáya‑Vai’séka ontological system, contains 18 fine‑grained categories under 10 nodes and maps to five standard coarse tags, ensuring compatibility with existing benchmarks. The dataset includes over 12.6K expert‑annotated entries and 108,335 entity mentions across 73,632 verses, plus a 5,000‑verse test set designed to challenge rare mentions, and the study compares generative NER models to traditional architectures, noting performance drops at finer granularity and difficulties with unseen entities.

arXiv:2607. 23319v1 Announce Type: cross Abstract: Standard subword tokenization algorithms such as Byte-Pair Encoding (BPE) and SentencePiece are trained predominantly on modern language corpora and produce inefficient segmentations when applied to classical Indian languages.

The paper compares generative and encoder-based neural models for multilingual Named Entity Recognition (NER) across the eleven languages of the Naamapadam benchmark. Five classic model families, four decoder-only large language models fine‑tuned with LoRA and 4‑bit NF4 quantisation, and nine generative models in zero‑to‑5‑shot inference were evaluated under strict CoNLL span‑level metrics. Encoder-based models (mBERT and XLM‑R) achieved substantially higher F1 scores—up to 0.675 on Hindi—than any generative architecture, with gaps of 7.5–40 percentage points; the best few‑shot result reached only 28% of the encoder baseline. The study identifies three language clusters (encoder‑dominant, partial‑coverage, and failure‑zone) and offers deployment guidelines based on transfer learning and low‑resource NLP principles.
