bert-base-multilingual-cased-classification-relation

This model is designed to classify spatial relations recognized from geographic encyclopedia articles. It is a fine-tuned version of the bert-base-multilingual-cased model. It has been trained on no-name-research/no-name-dataset, a manually annotated subset of 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).

Model Description

Authors: xxxxxxxxxx
Model type: Text classification
Repository: xxxxxxxxxxx

Class labels

The tagset is as follows:

Adjacency:
Crosses:
Distance-Orientation:
Inclusion:
Movement:
Other:

Dataset

The model was trained using the no-name-research/no-name-dataset dataset. The dataset is splitted into train, validation and test sets which have the following distribution of entries among classes:

	Train	Validation	Test
Adjacency	498	59	75
Crosses	397	50	29
Distance-Orientation	1,065	163	115
Inclusion	1,319	131	156
Movement	184	15	35
Other	195	30	42

How to Get Started with the Model

Use the code below to get started with the model.

python

import torch
from transformers import pipeline, AutoTokenizer, AutoModelForSequenceClassification
device = torch.device("mps" if torch.backends.mps.is_available() else ("cuda" if torch.cuda.is_available() else "cpu"))

ner = pipeline("token-classification", model="no-name-research/camembert-token-classification", aggregation_strategy="simple", device=device)
relation_classifier = pipeline("text-classification", model="no-name-research/multilingual-bert-spatial-relations-classifier", truncation=True, device=device)

def get_context(text, span, ngram_context_size=5):
    word = span["word"]
    start = span["start"]
    end = span["end"]
    label = span["entity_group"]

    # Extract context
    previous_text = text[:start].strip()
    next_text = text[end:].strip()
    previous_words = previous_text.split()[-ngram_context_size:]
    next_words = next_text.split()[:ngram_context_size]

    # Build context string
    context = f"[{word}]: {' '.join(previous_words)} {word} {' '.join(next_words)}"
    return word, context, label

content = "WINCHESTER, (Géog. mod.) ou plutôt Wintchester, ville d'Angleterre, capitale du Hampshire, sur le bord de l'Itching, à dix-huit milles au sud-est de Salisbury, & à soixante sud-ouest de Londres. Long. 16. 20. latit. 51. 3."

spans = ner(content)
for span in spans:
    if span['entity_group'] == 'Relation':
        word, context, label = get_context(content, span, ngram_context_size=5)
        print(f"Relation: {word}")

        label = relation_classifier(context)
        print(f"Predicted label: {label}")


# Output
Relation: sur le bord de
Predicted label: [{'label': 'Crosses', 'score': 0.9778845906257629}]
Relation: à dix-huit milles au sud-est de
Predicted label: [{'label': 'Distance-Orientation', 'score': 0.9959626793861389}]
Relation: à soixante sud-ouest de
Predicted label: [{'label': 'Distance-Orientation', 'score': 0.9963018894195557}]

Bias, Risks, and Limitations

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