Hierarchical Knowledge Bases and Efficient Disjunctive Reasoning

by Alex Borgida, David W. Etherington , 1989
"... We combine ideas from relation-based data management with class hierarchies to obtain Hierarchical Knowledge Bases, which have greater expressive power while maintaining the benefits of predictable and efficient information processing. We then consider the problem of reasoning with certain limited f ..."

, and approximations guided by the structure of the domain theory. Because of the structure imposed on the knowledge base, it is possible to characterize the potential error in any approximation. 1 Introduction It is fashionable to view a knowledge base (KB) as an integral utility invoked by a problem-solving program

Hierarchical Intelligent Simulation

by Tudor Niculiu Sorin, Sorin Cotofana
"... Separating the different hierarchy types reveals their comprehensive constructive importance based on structural approach, symbolic meaning, object-oriented representation, their combination in looking for self-organization, self-control and conscience. Knowledge and construction hierarchies can coo ..."

cooperate to integrate design and verification into simulation; object-oriented concepts can be symbolized to handle data and operations formally; structural representation of behavior manages its realization. Hierarchy types open, or at least show, the way to simulate intelligence as adaptable

Hierarchical Intelligent Mixed Simulation

by Tudor Niculiu Sorin, Sorin Cotofana
"... Intelligence is complementary to faith - common name for (intuition, inspiration, imagination) - and supposes, at least, {conscience, adaptability, intention). Conscience simulation demands transcending the present limits of computability, by an intensive effort on extensive research to integrate es ..."

An Approach to Natural Speech Understanding Based on Stochastic Models in a Hierarchical Structure

by Holger Stahl, Johannes Müller - Proc. Workshop 'Modern Modes of Man-Machine -Communic , 1994
"... In this paper, an approach for understanding natural speech by means of two stochastic knowledge bases is presented: Within a given domain, the semantic model generates possible semantic structures, which are semantic representations close to the word level. Corresponding to such a semantic structu ..."

Precise Environmental Searches: Integrating Hierarchical Information Search with EnviroDaemon

by George Chang, GUNJAN SAMTANI, Marcus Healey, Franz Kurfess, Jason Wang
"... Information retrieval has evolved from searches of references, to abstracts, to documents. Search on the Web involves search engines that promise to parse full-text and other files: audio, video, and multimedia. With the indexable Web at 320 million pages and growing, difficulties with locating rele ..."

The main emphasis of this paper lies in the treatment of structured knowledge, where essential aspects about the topic of interest are encoded not only by the individual items, but also

The Feasibility Study of Applying Fuzzy Structural Modeling on Knowledge Structure Analysis

by Yuan-horng Lin, He-kai Chen
"... Abstract: The purpose of this study is to apply an integrated algorithm for knowledge structure analysis. The integrated algorithm includes Item Response Theory (IRT) and Fuzzy Structural Modeling (FSM). The authors use the psychometric model IRT for calculation the ability of task-takers. Based on ..."

on original response data and item-concept matrix, the individualized fuzzy subordinate matrix is acquired. FSM is applied in the fuzzy subordinate matrix so that individualized knowledge structures is depicted by the hierarchical graphs. According to the empirical data analysis of mathematics test, it shows

Project STIMMULIS: Science Teachers Integrating Mathematical Modeling for Undergraduate Learning and Instruction in Schools

by William H. Robertson, William H. Robertson, Ph. D , 2010
"... Abstract: Computer-based mathematical modeling in Physics is a process of constructing models of concepts and the relationships between them in the scientific characteristics of work. In this manner, computer-based modeling integrates the interactions of natural phenomenon through the use of models, ..."
