Describe Library Resources with Knowledge Graph

Libraries have large amount of credible knowledge. But unfortunately, advanced Internet search tools and knowledge graphs cannot fully cover the valuable library collections. Using knowledge graph to describe collections can optimize knowledge services in several aspects. Specifically, the application of knowledge graph can help library enhance retrieval efficiency, integrate various resources and improve reference services. In order achieve these improvements, National Science Library of Chinese Academy of Sciences tries to build a knowledge graph connecting all the collections and open resources. The work of academic knowledge graph has been completed. However, in order to reveal the semantic connection of resources, a concept knowledge graph still needs to be working on, which is the focus of this research. This study proposes a process of constructing concept knowledge graph and discusses possible applications of knowledge graph in library.
