A Semantic Knowledge GraphAggregation of Library Resources

Abstract

In December 2022 the National Library Board Singapore (NLB) launched a continuously updated, Linked Data based, semantic Knowledge Graph (KG) to manage and aggregate resources extracted from their library management, authority management, National Archives, and, content management systems. Since then, developments have proceeded to utilise the data and functionality from the KG for sharing across the web and embedding in other NLB hosted services. Additionally, processes have been implemented to use external authority services, such as the Library of Congress, to enrich and improve the data quality of KG entities.
