This resource could be an aid to beginner ESL learners who struggle with common words. However, most words I encountered that I had to look up recently give empty or misleading results.<p>E.g., “aleph” results in an empty graph, and “heron” results in a false graph where all relations are to semantically unrelated “hero” except one to “Heron” the person. WordNet dataset actually does define “heron” as a bird, but somehow that was lost.
