The work Product Knowledge Graph Embedding for E-commerce proposes a model for embedding a Product Knowledge Graph (PKG), capturing the essence of product relationships for e-commerce applications such as marketing and recommendations.

• Entity Definition: Defining critical entities for understanding product relationships.
• PKG vs. Ordinary KG: Differences between product-focused and generic knowledge graphs.
• Embedding Techniques: Building PKG representations from customer activity data.
• Downstream Benefits: Enhancing search rankings and recommendations.

The model’s utility lies in its ability to handle complex entity structures and improve e-commerce processes. By providing a constructive comparison between PKG and ordinary knowledge graphs, the study offers fresh insights for AI-driven e-commerce solutions.
