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
