This is a fine-tuned model developed for the research paper "ParliaBench: An Evaluation and Benchmarking Framework for LLM-Generated Parliamentary Speech".

The model is trained to:

Generate UK-style parliamentary debates
Produce party-conditioned political arguments
Model parliamentary dialogue structures
Perform topic-aware generation using 21 EuroVoc topic categories

2. Base Model

Base model: "mistralai/Mistral-7B-v0.3"

This repository contains only LoRA adapter weights.
The base model must be loaded separately.

3. Training Data

The model was trained using:

ParlaMint-GB from Clarin
Preprocessed into:
- Structured debates
- Speaker metadata
- Section headers
- 21-class topic labels

5. Intended Uses

This model is designed for:

Political debate simulation
Parliamentary dialogue generation
Academic NLP research
Social behavior modeling

6. Limitations

May reproduce political biases present in the corpus
Not suitable for real political advice or predictions
Model outputs are synthetic and not factual

7. Ethical Considerations

Avoid using for political persuasion
Use strictly in academic and research contexts
Outputs may reflect UK political biases from the dataset
