OWL Web Visualizer

This project is a 3D web-based visualizer for ontologies (ttl files), built on top of the 3D Force-Directed Graph library.

Features

• Fast Deployment: Easily deploy the visualizer on your platform.
• File Upload: Use the "Load" button to upload your .ttl (Turtle) ontology files.
• Interactive Exploration: Navigate, search, and visualize the ontology with the implemented tools.
• Node Expansion: Click on nodes to expand them and reveal more connections within the ontology.
• Node Deletion: Remove nodes to declutter the visualization and focus on specific parts of the ontology (it does not delete the node from the db).
• Search Functionality: The system retrieves and displays text from the ontology that matches the search query, with case-insensitive matching.

Deployment Instructions

To deploy the OWL Web Visualizer and its dependencies using Docker Compose, follow these steps:

1. Clone the Repository

First, clone the repository to your local machine:

git clone https://github.com/yourusername/yourrepository.git
cd yourrepository

2. Start the service using docker-compose

docker-compose up --build

3. Access the OWL Web Visualizer

The project starts at: http://localhost:5005

How it works

This project uses a Neo4j database to manage and visualize ontology data. Upon uploading a .ttl file, the system automatically generates a Neo4j database, creating nodes and edges based on the ontology structure. The visualizer initially displays the first 10 nodes along with their respective connections.

Component Overview

• ExploreOWL: Handles the upload function and the creation of the Neo4j database.
• Neo4JConnector: Manages interactions with the Neo4j database.
• DataObject: Facilitates data transfer between components.
• API: UI and connections.

Project Background

This visualizer is a sub-component of the larger MindBugs Discovery Project, where it is utilized to identify disinformation patterns. You can find the source code for the broader project here.
