A Simple PoC (Proof of Concept) of Sentiment Analysis API Server. API server currently using cardiffnlp/twitter-roberta-base-sentiment-latest model for sentiment analysis. cardiffnlp/twitter-roberta-base-sentiment-latest or TimeLM-21 achieves top score 73.7 in Macro Averaged-Recall metric and becomes top state-of-the-art model in sentiment analysis for twitter/social media text.

sentiment-analysis-api is a core dependency of nostr-filter-relay.

A demo gradio instance is available on HuggingFace Spaces - https://huggingface.co/spaces/rifatramadhani/sentiment-analysis.

You can start by cloning this repository to run or modify it locally

git clone https://github.com/atrifat/sentiment-analysis-api
cd sentiment-analysis-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/sentiment-analysis-api.

Run it:

docker run --init --env-file .env -p 5000:5000 -it ghcr.io/atrifat/sentiment-analysis-api

or run it in the background (daemon):

docker run --init --env-file .env -p 5000:5000 -it --name sentiment-analysis-api -d ghcr.io/atrifat/sentiment-analysis-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:

{"negative":0.007959462702274323,"neutral":0.04862939938902855,"positive":0.943411111831665}
