xlm-roberta-base-finetuned-recipe-all

This model is a fine-tuned version of xlm-roberta-base on the recipe ingredient NER dataset from the paper A Named Entity Based Approach to Model Recipes (using both the gk and ar datasets).

It achieves the following results on the evaluation set:

• Loss: 0.1169
• F1: 0.9672

On the test set it obtains an F1 of 0.9615, slightly above the CRF used in the paper.

Model description

Predicts tag of each token in an ingredient string.

Intended uses & limitations

• Only trained on ingredient strings.
• Tags subtokens; tag should be propagated to whole word
• Works best with pre-tokenisation splitting of symbols (such as parentheses) and numbers (e.g. 50g -> 50 g)
• Typically only detects the first ingredient if there are multiple.
• Only trained on two American English data sources
• Tags TEMP and DF have very few training data.

Training and evaluation data

Both the ar (AllRecipes.com) and gk (FOOD.com) datasets obtained from the TSVs from the authors' repository.

Training procedure

It follows the overall procedure from Chapter 4 of Natural Language Processing with Transformers by Tunstall, von Wera and Wolf.

See the training notebook for details.
