## KGE-training Project Guide: Knowledge Graph Embedding Model Training and Visualization Practice

KGE-training is an open-source knowledge graph embedding (KGE) model training project developed by eightTT. It completes the training and evaluation of TransE and RotatE models on the classic FB15K dataset, and visualizes the underlying reasoning structure learned by the models through t-SNE dimensionality reduction. This project provides a complete practical reference for beginners in the KGE field.

## Technical Background and Project Significance of Knowledge Graph Embedding

Knowledge graph embedding is a core technology in knowledge representation learning, which maps entities and relationships into a low-dimensional vector space while preserving semantic structure and reasoning capabilities. Traditional symbolic knowledge graphs are difficult to directly apply to machine learning, but embedding technology enables numerical representation, semantic preservation, reasoning capabilities, and support for downstream applications. This project provides practical cases for beginners.

## Core Methods: FB15K Dataset and TransE/RotatE Models

### FB15K Dataset
- Source: Freebase knowledge base
- Scale: 14,951 entities, 1,345 relationships, 483,142 training triples
- Features: Multi-domain, complex relationship patterns

### TransE Model
- Core assumption: Relationships are translation operations between entities (h + r ≈ t)
- Scoring function: -||h + r - t|| (L1/L2 distance)
- Advantages and disadvantages: Simple and efficient, but struggles with complex relationships

### RotatE Model
- Core innovation: Rotation operation in complex space (t = h ∘ r)
- Capabilities: Models symmetric, inverse, and compositional relationships
- Technique: Self-adversarial negative sampling to improve performance

## Experimental Results and t-SNE Visualization Analysis

### Model Performance
- TransE: Performs well on one-to-one relationships, but performance drops on complex relationships
- RotatE: Overall better than TransE, with significant improvements in MRR and Hits@10

### t-SNE Visualization
- Clustering phenomenon: Semantically similar entities form clusters
- Relationship patterns: Translation/rotation trajectories are visible
- Value: Verify model representations, detect anomalies, and understand reasoning

## Application Scenarios and Value of Knowledge Graph Embedding

Knowledge graph embedding technology has a wide range of applications:
- Knowledge graph completion: Predict missing triples
- Intelligent question answering: Understand questions and retrieve answers
- Recommendation systems: Enhance recommendation effectiveness
- Semantic search: Retrieve based on semantic similarity
- Drug discovery: Predict drug-target relationships
- Financial risk control: Identify implicit corporate associations

## Learning Path Recommendations and Related Resource Suggestions

### Learning Path
- Basics: Knowledge graph concepts, vector embedding fundamentals, PyTorch/TensorFlow
- Intermediate: Understanding classic models, negative sampling and loss functions, dataset practice
- Advanced: Research on complex models, integration of KGE with LLM, application development

### Resource Recommendations
- Papers: TransE (NIPS 2013), RotatE (ICLR 2019)
- Tools: LibKGE, OpenKE, DGL-KE
- Datasets: FB15K/FB15K-237, WN18/WN18RR, YAGO3-10

## Project Summary and Outlook for the KGE Field

The KGE-training project provides a concise and complete practical case for KGE beginners. As a bridge connecting symbolic and vector representations, knowledge graph embedding is becoming increasingly important in the AI field. The current cutting-edge direction is the integration of KGE with large language models. This project serves as an entry-level reference and can support complex applications after improvements.
