If we are to understand how we can build machines capable of broad purpose learning and reasoning, we must first aim to build systems that can represent, acquire, and reason about the kinds of commonsense knowledge that we humans have…

The FAA is developing the Local Area Augmentation System (LAAS) to replace ground-based navigation aids as the primary means of aircraft precision approaches. Stringent requirements on the integrity of the system have caused significant delays and raised questions about the…

(cont.) which is expected, given their additional knowledge resources. The respondents' urgency in looking for the relevant knowledge is the primary explanation for this difference between the two networks. This difference in knowledge networking among the different groups did not…

This thesis examines the evolution of Internet based knowledge networks (e-knowledge networks) in the domain of sustainable development. The objective of this thesis is to use an engineering systems approach to understand knowledge networks, identify the barriers to their sustainability…

The goal of the work reported here is to capture the commonsense knowledge of non-expert human contributors. Achieving this goal will enable more intelligent human-computer interfaces and pave the way for computers to reason about our world. In the domain…

Knowledge-intensive processes are widely used to recover from errors, handle exceptional cases and complaints, and to improve or adapt a process itself. In this context, evolved Business-Process Reengineering (BPR) techniques are changing to give some answers to this reality. In…

Freud's theory of jokes explains how they overcome the mental "censors" that make it hard for us to think "forbidden" thoughts. But his theory did not work so well for humorous nonsense as for other comical subjects. In this essay…

Foreign Affairs – as a practical activity, science or/and a form of arts – ask for solid interdisciplinary knowledge, as well as a series of inter-relationship abilities that are to be displayed inside and outside the country. The author has…

ABSTRACT The Immediate Feedback Assessment Technique (IFAT) is a new multiple-choice response form that has advantages over more commonly used response techniques. The IFAT, which is commercially available at reasonable cost and can be used conveniently with large classes, has…

Omega is a description system for knowledge embedding which incorporates some of the attractive modes of expression in common sense reasoning such as descriptions, inheritance, quantification, negation, attributions and multiple viewpoints. A formalization of Omega is developed as a framework…
