A knowledge graph can be intuitively described as an encyclopedia for machines. It contains knowledge formatted in a way that can be understood and reasoned about by computers. The Ambiverse knowledge graph consists of three main elements: named entities, categories and facts.
A useful aspect about named entities is that they are categorizable. They can be grouped into persons, locations, organizations, products, or any other category and each category, in turn, can be further subcategorized. For example, a person can be a singer like Bob Dylan or an inventor like Steve Jobs; a product can be an album (e.g., Highway 61 Revisited) or a guitar (e.g., Gibson Hummingbird). This forms the hierarchical tree in which the nodes are categories, and the leaves are named entities.
Our knowledge graph contains entity names in English, but also Chinese, German, and Spanish.
