GRAPH-DRIVEN ANALYSIS AND VISUALISATION OF FREEBASE SCHEMA AS A DIRECTED WEIGHTED GRAPH (Published)
Freebase can be considered as one of the largest sources in the Linked Open Data (LOD) cloud. The paper adopts a graph-driven approach to analyse and visualise Freebase schema. Firstly, the paper demonstrates the extraction process of Freebase schema through stepwise procedures that maintain the schema structure. Secondly, the extracted types and relationships are utilised to represent Freebase schema as a directed weighted graph. Furthermore, the schema graph is used to conduct graph-based analysis and visualisation that can describe and summarise the schema structure and organisation of Freebase data.
