How to Use a Knowledge Graph

Intelligent Personal AssistantsPersonal assistant are changing the way we access the information on the web as search enginesSearch engine changed it years ago. Undoubtfully, an important factor that enables this way of consuming the web is the schema.orgSchema.org annotationsAnnotations on websites. Those annotationsAnnotations are extracted and then consumed by search engines and Intelligent Personal AssistantsPersonal assistant to support tasks like question-answering. In this section we explain how Knowledge Graphs built based on content, data, and service annotationsAnnotations can improve search engine results and conversational systems. We first give a brief overview of the history of the Internet, AI, and web and the role semantic technologies is playing in bringing those three to the point we are today. Then we show the need for an abstraction layer over Knowledge Graphs where we can create different knowledge views in order to achieve scalable curation, reasoning, and access control. Finally, we show how Knowledge Graphs can power conversational agents in different points in the dialog system Dialog system pipeline and the promising future of service annotationsAnnotations helping to build flexible systems decoupled from the web services with which they communicate.
