ySights - Extract insights from YSocial simulations

ySights - YSocial Data Analysis Made Simple

A Python library for analyzing data from YSocial simulations. ySights provides comprehensive tools for extracting insights from social media simulation data, including agent behaviors, content dynamics, network structures, and recommendation system effects.

Features

• 📊 Data Models: Comprehensive classes for agents, posts, and simulation data
• 🔍 Network Analysis: Social network extraction and analysis capabilities
• 🧮 Algorithms: Profile similarity, paradox detection, and recommendation metrics
• 📈 Visualization: Rich visualization functions using matplotlib and plotly
• 📚 Documentation: Complete Sphinx documentation with examples
• 🔄 CI/CD: Automated testing, formatting, and package distribution

Installation

From PyPI (recommended)

pip install ysights

With PostgreSQL Support

If you want to use PostgreSQL databases instead of SQLite:

pip install ysights[postgresql]

From Source

git clone https://github.com/YSocialTwin/ysights.git
cd ysights
pip install -e .
# Or with PostgreSQL support:
pip install -e .[postgresql]

Using Conda

conda install -c conda-forge ysights

Quick Start

Using SQLite (default)

from ysights import YDataHandler

# Initialize data handler with your SQLite simulation database
ydh = YDataHandler('path/to/simulation.db')

# Get simulation time range
time_range = ydh.time_range()
print(f"Simulation: rounds {time_range['min_round']} to {time_range['max_round']}")

# Get all agents
agents = ydh.agents()
print(f"Total agents: {len(agents.get_agents())}")

# Extract social network
network = ydh.social_network()
print(f"Network: {network.number_of_nodes()} nodes, {network.number_of_edges()} edges")

# Get posts by a specific agent
agent_id = 1
posts = ydh.posts_by_agent(agent_id)
print(f"Agent {agent_id} created {len(posts.get_posts())} posts")

Using PostgreSQL

from ysights import YDataHandler

# Initialize data handler with PostgreSQL connection string
ydh = YDataHandler('postgresql://user:password@localhost:5432/ysocial_db')

# Use the same API - all methods work identically
agents = ydh.agents()
network = ydh.social_network()

Note: ySights supports both SQLite and PostgreSQL databases with the same table structure. The API is identical regardless of which database you use.

Main Components

1. Data Models (ysights.models)

• YDataHandler: Main interface for database operations (supports both SQLite and PostgreSQL)
• Agents/Agent: Classes for representing individual agents and agent collections
• Posts/Post: Classes for representing posts and post collections

from ysights import YDataHandler

# Works with both SQLite and PostgreSQL
ydh = YDataHandler('simulation.db')  # SQLite
# ydh = YDataHandler('postgresql://user:pass@host/db')  # PostgreSQL

# Get agents by feature
young_agents = ydh.agents_by_feature('age', 25)

# Get agent interest profile
profile = ydh.agent_interest_profile(agent_id=1)

2. Algorithms (ysights.algorithms)

Profile Analysis

from ysights.algorithms import profile_topics_similarity

# Calculate profile similarity across the network
similarity = profile_topics_similarity(ydh, network)

Recommendation Metrics

from ysights.algorithms import engagement_momentum, personalization_balance_score

# Analyze engagement momentum
momentum = engagement_momentum(ydh, time_window_rounds=24)

# Calculate personalization balance
balance = personalization_balance_score(ydh)

Topic Analysis

from ysights.algorithms import topic_spread, adoption_rate, peak_engagement_time

# Analyze topic dynamics
spread = topic_spread(ydh, topic_id=5)
adoption = adoption_rate(ydh, topic_id=5)
peak_time = peak_engagement_time(ydh, topic_id=5)

3. Visualization (ysights.viz)

Global Trends

from ysights.viz import (
    daily_contents_trends,
    trending_hashtags,
    trending_emotions
)

# Visualize daily content trends
fig = daily_contents_trends(ydh)
fig.show()

# Show top trending hashtags
fig = trending_hashtags(ydh, top_n=10)
fig.show()

Topic Visualizations

from ysights.viz import topic_density_temporal_evolution

# Visualize topic evolution over time
fig = topic_density_temporal_evolution(ydh, min_days=15)
fig.show()

Profile Analysis

from ysights.viz import (
    profile_similarity_distribution,
    profile_similarity_vs_degree
)

# Visualize profile similarity
fig = profile_similarity_distribution([similarity], ['All Users'])
fig.show()

Documentation

Comprehensive documentation is available at ysights.readthedocs.io

Building Documentation Locally

cd docs
pip install -r requirements.txt
make html

The generated HTML documentation will be in docs/build/html/.

Development

Setting Up Development Environment

git clone https://github.com/YSocialTwin/ysights.git
cd ysights
pip install -r requirements.txt
pip install -e .

Code Formatting

This project uses Black for code formatting and isort for import sorting:

# Install formatting tools
pip install black isort flake8

# Format code
black ysights/
isort ysights/

# Check formatting
black --check ysights/
isort --check-only ysights/
flake8 ysights/

Running Tests

# Install test dependencies
pip install pytest

# Run tests
pytest ysights/test/

Note: Some tests require simulation database files and will be skipped if not available.
