Reasons: belief support and goal dynamics.

Cristiano Castelfranchi (1996)

Mathware and Soft Computing

Similarity:

The paper is devoted to the structural relation between beliefs and goals. I discuss its importance in modelling cognitive agents; its origin in cognitive processing; its structure (belief structure relative to a goal); its crucial role in rationality, mediating between epistemic and pragmatic rationality; its role in goal Dynamics. I stress the crucial contribution of the supporting beliefs to the Processing of goals; to the Revision of goals (or Dynamics in a narrow sense), i.e. the...

Statistical and decision theoretic aspects of examination assessment.

Simon French (1989)

Trabajos de Estadística

Similarity:

At a recent conference in Innsbruck, held in memory of Bruno De Finetti, attention focused on one of his aphorisms: analysts should think about things. This paper seeks to do precisely that in the context of public examinations in England and Wales. It attempts to think about those quantitative things that are done to marks in the process of assessing candidate scripts. Public examinations are central to our education system: hundreds of thousands of candidates enter them every year....

The HeKatE methodology. Hybrid engineering of intelligent systems

Grzegorz J. Nalepa, Antoni Ligęza (2010)

International Journal of Applied Mathematics and Computer Science

Similarity:

This paper describes a new approach, the HeKatE methodology, to the design and development of complex rule-based systems for control and decision support. The main paradigm for rule representation, namely, eXtended Tabular Trees (XTT), ensures high density and transparency of visual knowledge representation. Contrary to traditional, flat rule-based systems, the XTT approach is focused on groups of similar rules rather than on single rules. Such groups form decision tables which are connected...

Contexts, locality and generality.

Paolo Bouquet, Enrico Giunchiglia, Fausto Giunchiglia (1996)

Mathware and Soft Computing

Similarity:

It has been recognized that AI programs suffer from a lack of generality, the first gross symptom being that a small variation to the problem being solved usually causes a major revision of the theory describing it. The lack of generality seems an unavoidable consequence of the process of approximating the world while building theories about it. In this paper we propose an approach where generality is achieved by formulating, for each problem at hand, an appropriate local theory, a theory...

How to secure a high quality knowledge base in a rulebased system with uncertainty

Beata Jankowska (2006)

International Journal of Applied Mathematics and Computer Science

Similarity:

Although the first rule-based systems were created as early as thirty years ago, this methodology of expert systems designing still proves to be useful. It becomes especially important in medical applications, while treating evidence given in an electronic format. Constructing the knowledge base of a rule-based system and, especially, of a system with uncertainty is a difficult task because of the size of this base as well as its heterogeneous character. The base consists of facts, ordinary...

Characterizing incommensurability on the basis of a contextual theory of language

Léna Soler (2004)

Philosophia Scientiae

Similarity:

In this article I present, first, a criticism of certain aspects of the way Martin Carrier characterizes semantic incommensurability on the basis of a contextual theory of language. Subsequently I introduce some distinctions and put forward some proposals in order to pursue the same project. It will be argued that two different conceptions of the notion “conditions of applications” and, correlatively, two different meanings of the clause “preservations of the inferential relations”,...
