lpkb = Low performance Knowledge Base

Colm Kennedy, David Whitten.

A knowledge base spanning common sense. Over 10,000 axioms, where each axiom is made of triples. The knowledge was based on a subset of the Open Mind corpus. The knowledge base is divided into three hundred contexts. Inference is carried out by spreading activation to other axioms with the same triple(s) and a simple threshold based on the number of triples in an axiom.
