Google Knowledge Panel

One of the best known Big Data applications on the Semantic Web is the Google Knowledge Graph, which was introduced in 2012. The Google Knowledge Graph is a semantic knowledge base to enhance traditional Search Engine Result Pages (SERPs) with semantic search information gathered from a wide variety of sources. For example, searching for the title of an action movie, the results will include similar movies, while searching for a particular inventor will show further inventors with similar research fields and awards. The Knowledge Graph contains more than half a billion objects and over 18 billion facts about relationships between different objects that help software agents “understand” the meaning of the search keywords, and these figures are constantly growing.

Google Knowledge Panel and Knowledge Carousel
Searching for an actor’s filmography on Google gives both a Knowledge Carousel and a Knowledge Panel, mainly based on structured data annotations and Linked Data
