We address the experiences of the DARPA High Performance Knowledge Bases (HPKB) (Cohen et al., 1998) project in practical knowledge representation. The purpose of the HPKB project was to develop new techniques for rapid development of knowledge bases. The goal of this paper is to describe several technical issues that arose in creation of practical KB content. HPKB PROJECT
1 Formalization We assume that all variables range over the positive real numbers, i.e. all formulae in the knowledge base should be true statements in the domain of positive real numbers.
This paper explores how a new knowledge base centred on an emerging technology in a declining industrial city can spill over into the surrounding environment. Using a qualitative approach, it presents an in-depth case study of a Swedish urban region in order to explore who the actors are, how they have collaborated in the process, and what the outcomes have been. It discusses the impact of a re...

The results of the entire project shall together with other assignments strengthen the knowledge base of innovation performers and policies in Europe and will serve to effectively support the ana...
Our goal is to be able to answer questions about text that go beyond facts explicitly stated in the text, a task which inherently requires extracting a “deep” level of meaning from that text. Our approach treats meaning processing fundamentally as a modeling activity, in which a knowledge base of common-sense expectations guides interpretation of text, and text suggests which parts of the knowl...
This paper describes how even a simple matcher, if it can detect simple relationships between statements in the knowledge base, will support many features that will make a knowledgebased consultation system appear to behave more intelligently. We describe three features that are useful during the knowledge acquisition phase (involving the building and testing of the knowledge base), and four fe...
