The ConceptNet Project V2.1
A Very-Large Semantic Network of Common Sense Knowledge

ConceptNet is a freely available commonsense knowledgebase and natural-
language-processing toolkit which supports many practical textual-
reasoning tasks over real-world documents right out-of-the-box (without
additional statistical training) including

- topic-jisting (e.g. a news article containing the
concepts, “gun,” “convenience store,” “demand money” and “make
getaway” might suggest the topics “robbery” and “crime”),

-affect-sensing (e.g. this email is sad and angry),

-analogy-making (e.g. “scissors,” “razor,” “nail clipper,” and “sword” are
perhaps like a “knife” because they are all “sharp,” and can be used
to “cut something”),

-text summarization

-contextual expansion

-causal projection

-cold document classification

-and other context-oriented inferences
