camembert-base-edda-span-classification

<!-- Provide a quick summary of what the model is/does. -->

This model is designed to identify and classify named entities (such as Spatial, Person, and MISC), nominal entities, spatial relations, and other relevant information such as geographic coordinates within French encyclopedic entries. It has been trained on the French Encyclopédie ou dictionnaire raisonné des sciences des arts et des métiers par une société de gens de lettres (1751-1772) edited by Diderot and d'Alembert (provided by the ARTFL Encyclopédie Project). Dataset: https://huggingface.co/datasets/GEODE/GeoEDdA

Class labels

<!-- Provide a list of tag detected by the model. -->

The tagset is as follows:

• —NC_Spatial: a common noun that identifies a spatial entity (nominal spatial entity) including natural features, e.g. ville, la rivière, royaume.
• —NP_Spatial: a proper noun identifying the name of a place (spatial named entities), e.g. France, Paris, la Chine.
• —Relation: spatial relation, e.g. dans, sur, à 10 lieues de.
• —Latlong: geographic coordinates, e.g. Long. 19. 49. lat. 43. 55. 44.
• —NC_Person: a common noun that identifies a person (nominal spatial entity), e.g. roi, l'empereur, les auteurs.
• —NP_Person: a proper noun identifying the name of a person (person named entities), e.g. Louis XIV, Pline, les Romains.
• —NP_Misc: a proper noun identifying entities not classified as spatial or person, e.g. l'Eglise, 1702, Pélasgique.
• —Head: entry name
• —Domain-Mark: words indicating the knowledge domain (usually after the head and between parenthesis), e.g. Géographie, Geog., en Anatomie.

Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->

This model was trained entirely on French encyclopedic entries and will likely not perform well on text in other languages or other corpora.

How to Get Started with the Model

Use the code below to get started with the model.

from transformers import pipeline
import torch
from datasets import load_dataset


pipe = pipeline("token-classification", model="GEODE/camembert-base-edda-span-classification", aggregation_strategy="simple", device=device)

content = "* ALBI, (Géog.) ville de France, capitale de l'Albigeois, dans le haut Languedoc : elle est sur le Tarn. Long. 19. 49. lat. 43. 55. 44."

print(pipe(content))

Training Details

Training Data

<!-- This should link to a Data Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. -->

The model was trained using a set of 2200 paragraphs randomly selected out of 2001 Encyclopédie's entries. All paragraphs were written in French and are distributed as follows among the Encyclopédie knowledge domains:

The spans/entities were labeled by the project team along with using pre-labelling with early models to speed up the labelling process. A train/val/test split was used. Validation and test sets are composed of 200 paragraphs each: 100 classified as 'Géographie' and 100 from another knowledge domain. The datasets have the following breakdown of tokens and spans/entities.
