Maps and Cartography resources linked in a Knowledge Graph for big audiences: the semantic web of National Geographic Institute

The National Geographic Institute of Spain (NGI) knowledge graph and semantic web is a project built with symbolic artificial intelligence based on a semantically interpreted knowledge graph, powered with GNOSS technology. The knowledge graph of the National Geographic Institute of Spain integrates more than 2 million geographical resources, coming from 3 different sources of NGI, described in a very expressive way and offers a set of interfaces for people that allow their discovery, exploration, navigation, search and visualization. We will present the data sources integrated; the digital semantic model defined for the cartographic resources and maps of NGI; the processes of semantic annotation, grouping and recognition of entities to build and enrich the NGI knowledge graph; and the main applications for the end-users, as well as the main challenge address during the development of the project. The framework for developers used to build the knowledge graph and the end-user applications is GNOSS Knowledge Graph Builder. In the talk we will present a demonstration of the semantic web for the public. Now, the access to the web is restricted to a group of test users.
