Semantic graphs, also known as knowledge graphs or semantic networks, build a graph network with semantic relationships connecting the nodes. They can be used to explore topics, data connectivity and perform network analysis.
One interesting application is path traversal to analyze the connectivity of a dataset. These semantic relationships can be between text, audio and/or images.
The illustration above demonstrates how a graph's relationships are used to walk a path between two totally unrelated snippets of text.
This path is starting with a person parachuting and uses the semantic graph's relationships to walk a path to a picture of a person holding a french horn.
