Amazon Neptune helps you build knowledge graph applications. A knowledge graph allows you to store information in a graph model and use graph queries to enable your users to easily navigate highly connected datasets. Neptune supports open source and open standard APIs to allow you to quickly leverage existing information resources to build your knowledge graphs and host them on a fully managed service.
For example, if a user is interested in the Mona Lisa, you can also help them discover other works of art by Leonardo da Vinci, or other works of art located in the Louvre. Using a knowledge graph, you can add topical information to product catalogs, build and query complex models of regulatory rules, or model general information.
