Sentiment Analysis Service

This project provides a sentiment analysis service using Clojure and Python. The service exposes a REST API to analyze the sentiment of text data.

Prerequisites

• Clojure: Ensure you have Clojure installed.

• Python: Ensure you have Python and pip installed, since you are going to need pysentimiento.

If you install conda, make sure to set the LD_LIBRARY_PATH as follows:
export LD_LIBRARY_PATH="$(python3-config --prefix)/lib"

It is convenient to use a tool to manage the environment on a per-project basis, like direnv. If you go down that route, you will find the .envrc file in the base folder of the project managing the environmental variables for you.

• Dependencies: The project uses the following libraries:

• ring

• reitit

• muuntaja

• libpython-clj2

• pysentimiento

Setup

1. Clone the repository:

git clone <repository-url>
cd <repository-directory>

1. Set up the environment:

Install Python dependencies:

pip install pysentimiento

Or create a conda environment and install pysentimiento.

Running the Service

1. Build the uberjar:

clj -T:build uber

2. Run the server:

java -jar target/sentiment-analysis-1.2.10-standalone.jar

3. Server will run on port 3000:
