Hi again! I want to write my first rule and as far as I know I should start with declaring classes (Nodes). I want to declare class/concept Invoice. So - I try to write in guile (after loading of the usual OpenCog modules): (ConceptNode "Invoice") But this gives error warning "possibly unbound variable 'ConceptNode'" and error message 'Unbound variable: ConceptNode'
I receive similar warning and error when I enter the following in the guile shell: (define InvoiceClass (ConceptNode "Invoice")) So - what is wrong with my understanding about ConceptNode, about classes and concepts. My intuition is that I should first declare concepts before using them in BindLink or other rules. How can I define knowledge in OpenCog? -- You received this message because you are subscribed to the Google Groups "opencog" group.
