# TopicGPT
[![arXiV](https://img.shields.io/badge/arxiv-link-red)](https://arxiv.org/abs/2311.01449) [![Website](https://img.shields.io/badge/website-link-purple)](https://chtmp223.github.io/topicGPT)

This repository contains scripts and prompts for our paper ["TopicGPT: Topic Modeling by Prompting Large Language Models"](https://arxiv.org/abs/2311.01449) (NAACL'24). Our `topicgpt_python` package consists of five main functions:
- `generate_topic_lvl1` generates high-level and generalizable topics.
- `generate_topic_lvl2` generates low-level and specific topics to each high-level topic.
- `refine_topics` refines the generated topics by merging similar topics and removing irrelevant topics.
- `assign_topics` assigns the generated topics to the input text, along with a quote that supports the assignment.
- `correct_topics` corrects the generated topics by reprompting the model so that the final topic assignment is grounded in the topic list.

## 📣 Updates
- [11/09/24] Python package `topicgpt_python` is released! You can install it via `pip install topicgpt_python`. We support OpenAI API, VertexAI, Azure API, Gemini API, and vLLM (requires GPUs for inference). See [PyPI](https://pypi.org/project/topicgpt-python/).
- [11/18/23] Second-level topic generation code and refinement code are uploaded.
- [11/11/23] Basic pipeline is uploaded. Refinement and second-level topic generation code are coming soon.

## 📦 Using TopicGPT
### Getting Started
1. Make a new Python 3.9+ environment using virtualenv or conda.
2. Install the required packages:
```
pip install topicgpt_python
```
- Set your API key:
```
# Run in shell
# Needed only for the OpenAI API deployment
export OPENAI_API_KEY={your_openai_api_key}

# Needed only for the Vertex AI deployment
export VERTEX_PROJECT={your_vertex_project} # e.g. my-project
export VERTEX_LOCATION={your_vertex_location} # e.g. us-central1

# Needed only for Gemini deployment
export GEMINI_API_KEY={your_gemini_api_key}

# Needed only for the Azure API deployment
export AZURE_OPENAI_API_KEY={your_azure_api_key}
export AZURE_OPENAI_ENDPOINT={your_azure_endpoint}
```
- Refer to https://openai.com/pricing/ for OpenAI API pricing or to https://cloud.google.com/vertex-ai/pricing for Vertex API pricing.

### Data
- Prepare your `.jsonl` data file in the following format:
```shell
{
"id": "IDs (optional)",
"text": "Documents",
"label": "Ground-truth labels (optional)"
}
```
- Put your data file in `data/input`. There is also a sample data file `data/input/sample.jsonl` to debug the code.
- Raw dataset used in the paper (Bills and Wiki): [[link]](https://drive.google.com/drive/folders/1rCTR5ZQQ7bZQoewFA8eqV6glP6zhY31e?usp=sharing).

### Pipeline
Check out `demo.ipynb` for a complete pipeline and more detailed instructions. We advise you to try running on a subset with cheaper (or open-source) models first before scaling up to the entire dataset.

0. (Optional) Define I/O paths in `config.yml` and load using:
```python
import yaml

with open("config.yml", "r") as f:
config = yaml.safe_load(f)
```
1. Load the package:
```python
from topicgpt_python import *
```
2. Generate high-level topics:
```python
generate_topic_lvl1(api, model, data, prompt_file, seed_file, out_file, topic_file, verbose)
```
3. Generate low-level topics (optional)
```python
generate_topic_lvl2(api, model, seed_file, data, prompt_file, out_file, topic_file, verbose)
```

4. Refine the generated topics by merging near duplicates and removing topics with low frequency (optional):
```python
refine_topics(api, model, prompt_file, generation_file, topic_file, out_file, updated_file, verbose, remove, mapping_file)
```
5. Assign and correct the topics, usually with a weaker model if using paid APIs to save cost:

```python
assign_topics(
api, model, data, prompt_file, out_file, topic_file, verbose
)
```

```
correct_topics(
api, model, data_path, prompt_path, topic_path, output_path, verbose
)
```

6. Check out the `data/output` folder for sample outputs.
7. We also offer metric calculation functions in `topicgpt_python.metrics` to evaluate the alignment between the generated topics and the ground-truth labels (Adjusted Rand Index, Harmonic Purity, and Normalized Mutual Information).
