EDUKG: a Heterogeneous Sustainable K-12 Educational Knowledge Graph. (arXiv:2210.12228v1 [cs.CL])

Web and artificial intelligence technologies, especially semantic web and
knowledge graph (KG), have recently raised significant attention in educational
scenarios. Nevertheless, subject-specific KGs for K-12 education still lack
sufficiency and sustainability from knowledge and data perspectives. To tackle
these issues, we propose EDUKG, a heterogeneous sustainable K-12 Educational
Knowledge Graph. We first design an interdisciplinary and fine-grained ontology
for uniformly modeling knowledge and resource in K-12 education, where we
define 635 classes, 445 object properties, and 1314 datatype properties in …
