  # roberta-base-finetuned-ner
  
  This model is a fine-tuned version of [roberta-base](https://huggingface.co/roberta-base) on the [PLOD-filtered](surrey-nlp/PLOD-filtered) dataset.
  It achieves the following results on the evaluation set:
  - Loss: 0.1148
  - Precision: 0.9645
  - Recall: 0.9583
  - F1: 0.9614
  - Accuracy: 0.9576
  
  ## Model description
  
  RoBERTa is a transformers model pretrained on a large corpus of English data in a self-supervised fashion. This means
  it was pretrained on the raw texts only, with no humans labelling them in any way (which is why it can use lots of
  publicly available data) with an automatic process to generate inputs and labels from those texts. 
  
  More precisely, it was pretrained with the Masked language modeling (MLM) objective. Taking a sentence, the model
  randomly masks 15% of the words in the input then run the entire masked sentence through the model and has to predict
  the masked words. This is different from traditional recurrent neural networks (RNNs) that usually see the words one
  after the other, or from autoregressive models like GPT which internally mask the future tokens. It allows the model to
  learn a bidirectional representation of the sentence.
  
  This way, the model learns an inner representation of the English language that can then be used to extract features
  useful for downstream tasks: if you have a dataset of labeled sentences for instance, you can train a standard
  classifier using the features produced by the BERT model as inputs.
  
  ## Intended uses & limitations

  ## Training and evaluation data
  
  The model is fine-tuned using [PLOD-Filtered](https://huggingface.co/datasets/surrey-nlp/PLOD-filtered) dataset.
  This dataset is used for training and evaluating the model. The PLOD Dataset is published at LREC 2022. The dataset can help build sequence labeling models for the task of Abbreviation Detection.
