Generalized Property Graphs(GPG) of Property-Value Structures for Knowledge Model

Abstract

As a popular emerging technology, knowledge graphs (KGs) have become a platform of Web-based knowledge applications and services. Two dominant graph-based knowledge models, RDF and LPG, are widely used to construct large-scale KGs. It is argued that these models have some limitations to cope with complicated knowledge structures. This paper proposes a noble generalized property graph model that can seamlessly realize knowledge structures with compact expressiveness and robust formalism. Since the proposed graph model is compatible with RDF and LPG, it can be practically applied to KGs with effective performance.
