Vulcan Inc.’s Project Halo is a multi-staged effort to create a Digital Aristotle, an application that will encompass much of the world's scientific knowledge and be capable of applying sophisticated problem-solving to answer novel questions. Vulcan envisions two primary roles for the Digital Aristotle: as a tutor to instruct students in the sciences, and(More)
Cycorp has developed a knowledge acquisition system, based on Cyc, that can engage a user in a natural-language mixed-initiative dialogue. In order to achieve a intelligent dialogue with the user, it employs explicit topicand user-modeling, a system of prioritized interactions, and a transparent agenda to which either the user or the system can add(More)
The Halo Pilot, a six-month effort to evaluate the state-ofthe-art in applied Knowledge Representation and Reasoning (KRR) systems, collaboratively developed a taxonomy of failures with the goal of creating a common framework of metrics against which we could measure interand intrasystem failure characteristics of each of the three Halo knowledge(More)
Eliciting complex logical rules directly from logic-naive subject matter experts (SMEs) is a challenging knowledge capture task. We describe a large-scale experiment to evaluate tools designed to produce SME-authored rule bases. We assess the quality of the rule bases with respect to the: 1) performance on the addressed functional task (military course of(More)
The KRAKEN toolset is a comprehensive interface for knowledge acquisition that operates in conjunction with the Cyc knowledge base. The KRAKEN system is designed to allow subject-matter experts to make meaningful additions to an existing knowledge base, without the benefit of training in the areas of artificial intelligence, ontology development, or logical(More)
Reflected light optical microscopy using a Nomarski prism and a differential interference contrast filter have been employed in concert to achieve a technique that provides an accurate color reference for thickness during the dimpling and ion milling of transparent transmission electron microscopy samples of 6H-SiC(000 1) wafers. The samples had thin films(More)
Introduction A central issue in building knowledgebased systems is making them available to and understandable by naive users. This demonstration shows how a user and a knowledge-based system can collaborate to both create new knowledge and to extract existing knowledge from a knowledge base via natural language. KRAKEN1 is an interface designed for users(More)
