Persian named entity recognizer optimized for CPU, with its own internal tok2vec. Labels: PER, LOC, ORG, DAT, MON, TIM, PCT.

Scored with spacy benchmark accuracy on the held-out PerDT test split.

Median of repeated nlp.pipe passes over the 146-document PerDT test split (23,825 tokens), timing the pipe only. Warmup pass discarded.

Trained on UD_Persian-PerDT, licensed CC BY-SA 4.0; this pipeline is therefore distributed under CC BY-SA 4.0 with attribution to the treebank authors. The ner component is trained on the NER layer shipped in UD_Persian-PerDT's not-to-release/ directory, so it shares the treebank's genre, tokenization and licence. Those labels are SILVER: the treebank README states they were produced by the BERT-based Beheshti-NER tagger (Taher et al., 2020) with manual corrections to extend recall. They were transferred onto this pipeline's tokenization by difflib alignment at a 99.86% transfer rate (scripts/transfer_perdt_ner.py); spans that could not be aligned exactly were dropped rather than guessed. Labels PER, LOC, ORG and DAT have 1,300 or more training examples each; MON (205), TIM (135) and PCT (121) are thin and their scores in performance.ents_per_type should be read before relying on them.
