Leveraging Cyc for the High Performance Knowledge Base (HPKB) Program

Abstract

This work was part of the DARPA High Performance Knowledge Base (HPKB) program. The work described in this final report has focused on providing to the HPKB program the robustness and effectiveness of common sense knowledge as embodied in the Cyc knowledge base. Its objective was to provide intermediate level knowledge necessary to tie together high level, abstract knowledge and low level application specific knowledge to ease integration of knowledge bases and provide more efficient and more powerful inferencing mechanisms. The pre-existing Cyc KB had tens of thousands of useful rules for HPKB Integrated Knowledge Base (IKB) to inherit, and the Cyc team had already analyzed the "perennial conceptual issues" for thirteen years prior to HPKB. Early adoption of Cyc's Public Upper Ontology as the "HPKB Jumpstart Ontology" gave both the Cycorp and SAIC teams a uniform, convenient, and reliable environment to add knowledge, ask questions and gather measurements.
