Knowledge Graph Technology

The benefits of knowledge graphs compared to traditional relationship databases are far reaching. Knowledge graphs offer more flexible and complex storage than their traditional counterparts, as well as provide a way to answer complex questions and apply reasoning to gain new insights from existing data. This allows end users to receive more expansive answers compared to a standard 1:1 coded answer for each question.

Many organizations are already using knowledge graph technology to help themselves stand out and provide more relevant, holistic and flexible information to their customers and employees. Services such as Alexa, Google Assistant and Siri have introduced the benefits and convenience of knowledge graphs to people of all ages.

At Appen, we are proud to be able to offer industry leading knowledge graph and ontology support services to help you build a robust, and powerful knowledge graph, turning your data into intelligence.
