Machine Learning in LinkedIn Knowledge Graph

LinkedIn knowledge graph is a large knowledge base built upon "entities" on LinkedIn, such as members, jobs, titles, skills, companies, geographical locations, schools, etc. These entities and the relationships among them form the ontology of the professional world and are used by LinkedIn to enhance its recommender systems, search, monetization and consumer products, business and consumer analytics. Creating a large knowledge base is a big challenge. Web sites like Wikipedia and Freebase primarily rely on direct contributions from human volunteers. Other related work such as Google's Knowledge Vault and Microsoft's Satori focuses on automatically extracting facts from the Web by leveraging the data redundancy nature of big data for constructing knowledge bases.
