Knowledge Graph Explorer (KGE) is an interactive, multimodal, visual tool for exploring very large knowledge graphs, such as those generated from Watson's distributional semantics algorithms or large public knowledge bases like DBpedia. KGE helps Watson ecosystem developers understand how certain core Watson algorithms work and the structure, coverage, and utility of available unstructured corpora.

Knowledge Graph Explorer was a collaboration between Watson Group's Cognitive Visualization Lab and Distributional Semantics team.
