Knowledge-Level Modularization of a Complex Knowledge Base

چکیده
An increasingly relevant theme for knowledge-based systems is how to model and use a large and complex knowledge domain. On the one hand, this involves developing new ideas on a modular construction of a knowledge base and, on the other hand, an appropriate architecture of a knowledge-based system that takes account of such a modular knowledge base. In the HYPERCON project we conceptualize a complex medical domain (hypertension) according to ideas of a knowledge-level modularization. In this paper, we give a brief account of our basic approach and describe in detail how specific knowledge is structured and accomodated in a modular knowledge base. Using a specific case of a patient with a kidney-related hypertension, we exemplify focussing procedures based on plan-and-tactics and on changing between different granularity levels in the course of a consultation.

Towards ABox Modularization of semi-expressive Description Logics
In the last years, the vision of the Semantic Web fostered the interest in reasoning over large and very large sets of assertional statements in knowledge bases. Traditional tableau-based reasoning systems perform bad answering queries over large data sets, because these reasoning systems are based on efficient use of main memory data structures. Increasing expressivity and worstcase complexity...
متن کاملConstructing a Legal Knowledge-base with Partial Information
In legal reasoning systems, a typical application of normative reasoning, partial information plays an important role in the representation and reasoning of legal knowledge. To construct a legal knowledge-base with partial information, many features are required of knowledge representation languages. In this paper, we discuss the representation of knowledge-bases and their re nement through our...
متن کاملMechanisms for Flexible Representation and Use of Knowledge in User Modeling Shell Systems
In many user modeling systems, assumptions about the user and other user modeling knowledge are represented in a knowledge base and used for individualized behavior of applications. Hence, user modeling shell systems need to support both representation and use of knowledge. Ideally, a shell provides powerful techniques for applications with sophisticated needs but is also flexible enough to be ...

Introduction: Information about vegetation cover and their health has always been interesting to ecologists due to its importance in terms of habitat, energy production and other important characteristics of plants on the earth planet. Nowadays, developments in remote sensing technologies caused more remotely sensed data accessible to researchers. The combination of these data improves the obje...
متن کاملInference Processes on Clustered Partial Decision Rules
The aim of the paper is to study efficeient of inference process using clustered partial decision rules. Partial decision rules are constructed by greedy algorithm. They are clustered with Agglomerative Hierarchical Clustering (AHC) algorithm. We study how exact and partial decision rules clustered by AHC algorithm influence on inference process in knowledge base. Clusters of rules are a way of...
