Embedding based entity summarization ISWC’19

Overview Motivation: Leverage the Knowledge graph embedding for entity summarization Contribution: We adopt (weakly) supervised learning to generate high-quality general-purpose training data for entity summarization without the relying on manually labeled data. We devise a context-based knowledge graph embedding fusion both semantic and structural information for entity summarization. The new embedding consider the difference in semantic meaning between facts in different contexts. And the approach results shows it achieve the state-of-the-art of entity summarization. We utilize the embedding with a learning-based ranking algorithm and diversity-oriented re-ranking to generate the final summarization of entity and achieve the state-of-the-art.
