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
It seems that facilitating conditions for knowledge sharing, like a shared understanding, a common language as well as the multifold and direct relations between are idiosyncrasies of a knowledge network. However, these facilitating conditions are limited if a high turn over rate is involved in a knowledge network. As a consequence, capability differences between knowledge network members will ...
In this paper we propose an epistemic concept language, where the epistemic operator is interpreted in terms of minimal knowledge. We show that the proposed formalism provides an adequate characterization of many non-rst-order aspects of frame-based knowledge representation systems, by admitting in the knowledge base various forms of epistemic sentences. In particular, we address the formalizat...
The problem of maintaining a knowledge base is substantially concerned with keeping track of rules that share common wisdom. A knowledge representation is described in which a collection of rules that are based on common wisdom are represented as a single ‘item’. For items, maintenance hazards, caused by one item being partially hidden within another, still remain. ‘Objects’ are introduced as i...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
Research currently in progress at the University of Bielefeld is concerned with conceptualizing a methodological framework which allows large-scale knowledge bases to be constructed, utilized and maintained in a modular fashion. Challenges to be met span from the modular conception of domain knowledge in a given application area on the one hand to the adaption of principles for modular system d...
A most crucial problem in knowledge representation is the revision of knowledge when new, possibly contradictory, information is obtained (belief revision). In this report, we address this problem when the knowledge base is a set of expressions in propositional logic. We introduce a new representation of propositional expressions using 2-dimensional matrices and provide the theoretical underpin...
