Model Description

• Developed by: Identrics
• Language: Bulgarian
• License: apache-2.0
• Finetuned from model: INSAIT-Institute/BgGPT-7B-Instruct-v0.2
• Context window : 8192 tokens

Model Description

This model consists of a fine-tuned version of BgGPT-7B-Instruct-v0.2 for a propaganda detection task. It is effectively a binary classifier, determining wether propaganda is present in the output string. This model was created by Identrics, in the scope of the WASPer project. The detailed taxonomy of the full pipeline could be found here.

Uses

Designed as a binary classifier to determine whether a traditional or social media comment contains propaganda.

Example

First install direct dependencies:

pip install transformers torch accelerate

Then the model can be downloaded and used for inference:

from transformers import pipeline

labels_map = {"LABEL_0": "No Propaganda", "LABEL_1": "Propaganda"}

pipe = pipeline(
    "text-classification",
    model="identrics/wasper_propaganda_detection_bg",
    tokenizer="identrics/wasper_propaganda_detection_bg",
)

text = "Газа евтин, американското ядрено гориво евтино, пълно с фотоволтаици а пък тока с 30% нагоре. Защо ?"

prediction = pipe(text)
print(labels_map[prediction[0]["label"]])

Training Details

The training dataset for the model consists of a balanced collection of Bulgarian examples, including both propaganda and non-propaganda content. These examples were sourced from a variety of traditional media and social media platforms and manually annotated by domain experts. Additionally, the dataset is enriched with AI-generated samples.

The model achieved an F1 score of 0.836 during evaluation.

Compute Infrastructure

This model was fine-tuned using a GPU / 2xNVIDIA Tesla V100 32GB.
