This paper is a revised version of part of a previous report (Give'on, 1962) which was prepared for the U. S. Office of Naval Rsearch, Information Systems Branch, under contract No. 62558-2214, at the Applied Logic Branch of the Hebrew University in Jerusalem, Israel (February 1962). This revision was done for the U. S. Office of Naval Research, Information Systems Branch, under contract No. No...

Intelligent Information systems do not usually possess complete information about the world with which they interact. The AGM paradigm has become one of the standard frameworks for modeling changes to repositories of information. Its principal constructions for change operators rely on some form of underlying preference relation. The process of changing such a preference relation is known as a ...

The revision history of a software system conveys important information about how and why the system evolved in time. The revision history can also tell us which parts of the system are coupled by common changes: “Whenever the database schema was changed, the sqlquery() method was altered, too.” This “evolutionary” coupling can be compared with the coupling as imposed by the system architecture...

In previous work (Nescolarde-Selva and Usó-Doménech, 2014a,b) discussed the theory that complex belief systems have a topological structure. In this paper it is suggested that this structure is also fuzzy. They introduce the concepts of fuzzy sets in the context of beliefs (substantive and derived) , and between derived beliefs themselves. Also introduced are the concepts of fuzzy covering, fuz...

ion and generalisation requires relating the idiographic details revealed by the data interpretation to theoretical, general concepts that describe the nature of human understanding and social action dialogical reasoning requires sensitivity to possible contradictions between the theoretical preconceptions guiding the research design and actual findings (‘the story which the data tell’) with su...

There is nowadays a lot of interest in the field of Instructional Design. The focus is still on theories and methodology of Instructional System Design (ISD), which are the fundamentals of the field and are absolutely important for its application. However, most professionals are involved in the daily practice of instructional design (ID). The practice of instructional design has a slightly dif...

Certain constraints that should be interpreted as definitions or quasi-definitions can cause prediction problems for logics of action. Standard ways to avoid them rely on notions of priority in the minimization of fluent change. We offer an alternative approach based on belief revision. Revision is performed on the reduct of the system theory after isolating definitions, and the revised theory ...
