In this article, we provide a comprehensive introduction to knowledge graphs, which have recently garnered significant attention from both industry and academia in scenarios that require exploiting diverse, dynamic, large-scale collections of data. After some opening remarks, we motivate and contrast various graph-based data models, as well as languages used to query and validate knowledge graphs. We explain how knowledge can be represented and extracted using a combination of deductive and…

This research aims at an explainable system with a specific knowledge graph architecture that can generate human-understandable results even when no suitable domain experts are available, and designs a framework of interpretation, and shows how interpretable models are generated.

Building Knowledge Graphs from Unstructured Texts: Applications and Impact Analyses in Cybersecurity Education

A bottom-up approach to curate entity-relation pairs and construct knowledge graphs and question-answering models for cybersecurity education is presented and results show that students found these tools informative for learning the core concepts and they used knowledge graphs as a visual reference to cross check the progress that helped them complete the project tasks.

GenomicKB: a knowledge graph for the human genome.

The Genomic Knowledgebase transforms complicated analysis among multiple genomic entities and relations into coding-free queries, and facilitates data-driven genomic discoveries in the future.
