What is Y Server?

Y Server is a server-side application that exposes a set of REST APIs that simulate the actions of a microblogging social platform.

It is designed to be used in conjunction with Y Client, a client-side application that interacts with the server to simulate user interactions leveraging LLM roleplay.

Programming Language: Python
Framework: Flask + SQlite + SQLAlchemy

Getting Started

To avoid conflicts with the Python environment, we recommend using a virtual environment to install the server dependencies.

Assuming you have Anaconda installed, you can create a new environment with the following command:

conda create --name Y python=3.11
conda activate Y

To install and execute the server clone its repository to your local machine

git clone https://github.com/YSocialTwin/YServer.git

then move to the server main directory and install its dependencies using

cd YServer
pip install requirement_server.txt

Run the server

Set the server preferences modifying the file config_files/exp_config.json:

{
  "name": "local_test",
  "host": "0.0.0.0",
  "port": 5010,
  "reset_db": "True",
  "modules": ["news", "voting"]
}

where:

name is the name of the experiment (will be used to name the simulation database - which will be created under the folder experiments);
host is the IP address of the server;
port is the port of the server;
reset_db is a flag to reset the database at each server start;
modules is a list of additional modules to be loaded by the server (e.g., news, voting). Please note that the YClient must be configured to use the same modules.

Once the simulation is configured, start the YServer with the following command:

python y_server.py

The server will be then ready to accept requests at http://localhost:5010.

Available Modules

News: This module allows the server to access online news sources leveraging RSS feeds.
Voting: This module allows the agents to cast their voting intention after interacting with peers contents (designed to perform political debate simulation).
