Acquisition of Gradual Knowledge

چکیده
Abs t rac t . Topoi are gradual inference rules, often used by experts in several problem classes: they can be exploited at various phases of a knowledge-based system life cycle. They can be studied at the two levels distinguished by Newelh the knowledge level and the symbol level. Some knowledge elicitation techniques such as rating grids and some knowledge acquisition methods such as KADS and KOD can be exploited in order to facilitate the acquisition of topoi. At the symbol level, different representations and implementations of topoi can be proposed and topoi can be formalized through several qualitative physics formalisms.

Although the acquisition knowledge has preparing and introductory relation with regard to practice and is considered as its required condition, it lacks enough capability for definite guarantee of practice. Explicating the function of the acquisition knowledge achieved from different faculties of the soul and analyzing its position in principles and process of practice can to some extent explai...
متن کاملEleventh Workshop on Knowledge Acquisition for Knowledge - Based Systems ( KAW ’ 98 ) , Banff , Alberta Characterising Problem Solving
This paper makes two contributions to the study of problem solving methods. First, we extend the current theory on how to characterise problem-solving methods. We show that the current theory is not strong enough, and does not allow the characterisation of many natural problem-solving methods. Secondly, we show that characterisations of problem-solving methods should be stated in gradual terms,...
متن کاملA Multistrategy Learning Approach to Domain Modeling and Knowledge Acquisition
This paper presents an approach to domain modeling and knowledge acquisition that consists of a gradual and goal-driven improvement of an incomplete domain model provided by a human expert. Our approach is based on a multistrategy learning method that allows a system with incomplete knowledge to learn general inference or problem solving rules from specific facts or problem solving episodes rec...
متن کاملPhrase Structure in a Computational Model of Child Language Acquisition
The problem of the acquisition of morpho-syntactic rules, as addressed by a number of existing computational models, is introduced. A distinction is made between ‘innatist’ models which presuppose the importance of innate linguistic knowledge (specifically, syntactic categories and X-Bar Theory), and ‘empiricist’ models, which reject such assumptions. It is argued that ‘empiricist’ models bette...
