Details

The OpenNE architecture is designed as a flexible, data-driven pipeline for graph embedding. The CLI Interface & Orchestrator serves as the central control point, guiding the execution flow. It initiates data processing via the Graph Data Loader, which prepares graph data for various embedding algorithms. Depending on the chosen algorithm, the Random Walk Generator may provide essential node sequences. The core functionality resides within the Graph Embedding Models component, an interchangeable collection of algorithms that transform graph data into low-dimensional embeddings. Finally, the Embedding Evaluation Module consumes these embeddings to assess their quality through downstream tasks. This modular design facilitates easy integration of new algorithms and clear separation of concerns, making it ideal for visual representation as a sequential data flow diagram.

CLI Interface & Orchestrator [Expand]

The primary entry point, responsible for parsing command-line arguments, configuring the execution flow, and orchestrating the entire pipeline from data loading to model execution and evaluation.

Random Walk Generator

A utility component dedicated to generating random walks on graphs. These sequences are crucial inputs for specific graph embedding algorithms that rely on node sequences to learn representations.

Graph Embedding Models

This is the central, interchangeable component group encompassing all implemented graph embedding algorithms. Each sub-component within this group takes graph data (and potentially random walks) as input and produces low-dimensional node or graph embeddings.
