Abstract:
Online social networks such as Facebook and LinkedIn have been an integrated part of people’s everyday life. To improve the user experience and power the products around the social network, Knowledge Graphs (KG) are used as a standard way to extract and organize the knowledge in the social network. This talk focuses on how to build Knowledge Graphs for social networks by developing deep NLP and GNN models, and holistic optimization of Knowledge Graphs and the social network. Building KG for social networks poses two challenges:
1) input data for each member in the social network is noisy, implicit and in multilingual, so a deep understanding of the input data is needed;
2) KG and the social network influence each other via multiple organic feedback loops, so a holistic view on both networks is needed. In this talk, I will share the lessons we learned from tackling the above challenges in the past 9 years on building the Knowledge Graph for the LinkedIn social network. I will present how we use our KG to empower more than 20+ products at LinkedIn with high business impacts.
What You’ll Learn:
You will learn:
1) the overview of the LinkedIn knowledge graph and its business impacts,
2) how does LinkedIn use deep learning techniques, leverage the graph structure, and incorporate the social network feedback to construct the LinkedIn knowledge graph.
Qi He is the Sr. Director of Engineering at LinkedIn, leading a team of 150+ machine learning scientists, software engineers and linguistic specialists to standardize LinkedIn data and build the LinkedIn Knowledge Graph by creating standard entity vocabulary, recognizing entities, building entity relationships, and use this data to serve the entire LinkedIn ecosystem including member engagement and monetization products. His strengths include 1) 15+ years of experience managing and executing large complex AI projects in Knowledge Mining and Management, Recommender Systems, Information Retrieval, Language Processing with big business impact, 2) inventing and driving adoption of the state-of-the-art Deep Learning and Natural Language Processing approaches in industry, 3) building a strong organization and scaling it across geographies.
