Model Details

Model Description

Developed by: 1-800-SHARED-TASKS
Funded by: Cohere's Research Compute Grant (July 2024)
Model type: Transformer-based for multilingual text portion detection
Languages (NLP): 23 languages (expanding to 102)

Presentation: Multi-lingual Machine-Generated Text Portion(s) Detection

Uses

The dataset is suitable for machine-generated text portion detection, token classification tasks, and other linguistic tasks. The methods applied here aim to improve the accuracy of detecting which portions of text are machine-generated, particularly in multilingual contexts. The dataset could be beneficial for research and development in areas like AI-generated text moderation, natural language processing, and understanding the integration of AI in content generation.

Training Details

The model was trained on a dataset consisting of approximately 330k text samples from LLMs Command-R-Plus (100k) and Aya-23-35B (230k). The dataset includes 10k samples per language for each LLM, with a distribution of 10% fully human-written texts, 10% entirely machine-generated texts, and 80% mixed cases.

Evaluation

Testing Data, Factors & Metrics

The model was evaluated on a multilingual dataset covering 23 languages. Metrics include Accuracy, Precision, Recall, and F1 Score at the word level (character level for Japanese and Chinese).

Results

Here are the word-level metrics for each language and ** character-level metrics for Japanese (JPN) and Chinese (ZHO):
