Eliezer is right, OpenCog it's not a knowledge base. It's (from Wikipedia): - An API to manipulate an extended hypergraph of terms and relationships, dubbed the "AtomSpace". - An implementation of a probabilistic reasoning engine based on probabalistic logic networks (PLN). - A probabilistic genetic program evolver called Meta-Optimizing Semantic Evolutionary Search, or MOSES, originally developed by Moshe Looks. - An attention allocation system based on economic theory. - An embodiment system for interaction and learning within virtual worlds. - A natural language input system consisting of Link Grammar and RelEx, both of which employ AtomSpace-like representations for semantic and syntactic relations. - A natural language generation system called SegSim, with implementations NLGen and NLGen2.
