Davlan/xlm-roberta-large-ner-hrl
language:
xlm-roberta-large-ner-hrl is a Named Entity Recognition model for 10 high resourced languages (Arabic, German, English, Spanish, French, Italian, Latvian, Dutch, Portuguese and Chinese) based on a fine-tuned XLM-RoBERTa large model. It has been trained to recognize three types of entities: location (LOC), organizations (ORG), and person (PER). Specifically, this model is a xlm-roberta-large model that was fine-tuned on an aggregation of 10 high-resourced languages
You can use this model with Transformers pipeline for NER.
from transformers import AutoTokenizer, AutoModelForTokenClassification from transformers import pipeline tokenizer = AutoTokenizer.from_pretrained("Davlan/xlm-roberta-large-ner-hrl") model = AutoModelForTokenClassification.from_pretrained("Davlan/xlm-roberta-large-ner-hrl") nlp = pipeline("ner", model=model, tokenizer=tokenizer) example = "Nader Jokhadar had given Syria the lead with a well-struck header in the seventh minute." ner_results = nlp(example) print(ner_results)Limitations and bias
This model is limited by its training dataset of entity-annotated news articles from a specific span of time. This may not generalize well for all use cases in different domains.
The training data for the 10 languages are from:
Language | Dataset |
---|---|
Arabic | ANERcorp |
German | conll 2003 |
English | conll 2003 |
Spanish | conll 2002 |
French | Europeana Newspapers |
Italian | Italian I-CAB |
Latvian | Latvian NER |
Dutch | conll 2002 |
Portuguese | Paramopama + Second Harem |
Chinese | MSRA |
The training dataset distinguishes between the beginning and continuation of an entity so that if there are back-to-back entities of the same type, the model can output where the second entity begins. As in the dataset, each token will be classified as one of the following classes:
Abbreviation | Description |
---|---|
O | Outside of a named entity |
B-PER | Beginning of a person’s name right after another person’s name |
I-PER | Person’s name |
B-ORG | Beginning of an organisation right after another organisation |
I-ORG | Organisation |
B-LOC | Beginning of a location right after another location |
I-LOC | Location |
This model was trained on NVIDIA V100 GPU with recommended hyperparameters from HuggingFace code.
