GovernmentGPT

An LLM fine-tuned on the British Commons Parliamentary Hansard to simulate the debate of political topics like members of parliament.

I wanted to see whether we can teach an LLM to do the job of elected British Members of Parliament (MPs) and debate any issue like they do in the House of Commons.

GovernmentGPT is an LLM fine-tuned with a LoRA adapter. This git repo contains all the code and data necessary to build the datasets, perform fine-tuning and do inference: https://github.com/stewhsource/GovernmentGPT/

If you're looking to see an interesting end-to-end example of an LLM fine-tuning pipeline on real-world data, then look no further!

The key parts of the data processing pipeline are described in the following sections:

Raw Data Extraction

The raw Hansard transcript and speaker data needed to create the training datasets sits in a few places and needs to be processed and linked together, ready to prepare the final training dataset. We only used Hansard data from 1997 onwards because it was easiest to link to the speaker data. The code to do that is here: https://github.com/stewhsource/GovernmentGPT/tree/main/DatasetPreparation.

Training Dataset Preparation

The code samples 'sequences' of real British Commons Parlimentary Hansard debate transcripts. It attaches the speaker data (eg affiliation, location, additional roles such as committee memberships), and then structures it in a format ready for LLM fine-tuning. It strips dates, MP names and some numeric linking identifiers present in the text to try and avoid the LLM reproducing with bias. There is much more work that can be done to aid generalisability in this regard.

You can download the final prepared JSONL datasets ready for fine-tuning here:

Fine-tuning

All code for fine-tuning is in this link. You can easily run this on your local machine if it has a GPU, or on Google Colab.

LLM Adapter

The Mistral 7b v0.3 adapter is available for download here on HuggingFace, ready for you to plug into your own inference pipeline.

Inference

You can run the fine-tuned model easily to generate your own debates using this link. As with fine-tuning, you can easily run this on your local machine if it has a GPU, or on Google Colab.

Parlimentary Hansard data

We make heavy use of British Commons Parliamentary Hansard data. While this data is openly available to use, a number of individual and organisations have kindly worked hard to make this data more accessible for machine processing:

mySociety (eg their data in: https://github.com/mysociety/parlparse/blob/master/members/ministers-2010.json)
mySociety TheyWorkForYou - Data APIs and dumps at https://data.theyworkforyou.com
