A Simple PoC (Proof of Concept) of Topic Classification API Server. API Server implementation currently using cardiffnlp/twitter-roberta-base-dec2021-tweet-topic-multi-all model for topic classification (multi-label). cardiffnlp/twitter-roberta-base-dec2021-tweet-topic-multi-all achieves score 0.764767 in F1 metric and becomes state-of-the-art model in topic classification (multi-label) for twitter/social media text.
topic-classification-api is a core dependency of nostr-filter-relay.
A demo gradio showcase is available on HuggingFace Spaces - https://huggingface.co/spaces/rifatramadhani/topic-classification.
You can start by cloning this repository to run or modify it locally
git clone https://github.com/atrifat/topic-classification-api
cd topic-classification-api
Create virtual environment using venv, pyenv, or conda. This is an example using venv to create and activate the environment:
python3 -m venv venv
source venv/bin/activate
install its dependencies
pip install -U -r requirements.txt
and run it using command
python3 app.py
You can also copy .env.example to .env file and change the environment value based on your needs before running the app.
There is also Dockerfile available if you want to build docker image locally. If you don't want to build docker image locally, you can use the published version in ghcr.io/atrifat/topic-classification-api.
Run it:
docker run --init --env-file .env -p 5000:5000 -it ghcr.io/atrifat/topic-classification-api
or run it in the background (daemon):
docker run --init --env-file .env -p 5000:5000 -it --name topic-classification-api -d ghcr.io/atrifat/topic-classification-api
If you want to test the API server, you can use GUI tools like Postman or using curl.
curl --header "Content-Type: application/json" \
--request POST \
--data '{"api_key":"your_own_api_key_if_you_set_them", "q":"hello world good morning"}' \
http://localhost:5000/predict
The result of classification will be shown as follow:
[{"label":"diaries_&_daily_life","score":0.7851732969284058},{"label":"other_hobbies","score":0.20930162072181702},{"label":"news_&_social_concern","score":0.09335983544588089}]
