WordNet? What's that?

Do even its sponsors know?

They say:

• "Dictionary based on psycholinguistic principles" (Miller et al., 1993, p. 2)
• "Machine-readable thesaurus"
• "Lexical database" (WordNet itself)
• "Lexical inheritance system" (Miller, 1993, p. 13)
• "Semantic network"
• "Lexical reference system" (README 2.0)
