Scrupulosity (also known as religious obsessive-compulsive disorder) is a sub-group of obsessive-compulsive disorder (OCD) that has not been well investigated internationally and in Iran. In recent decades, scrupulosity has been the researchers’ subject of interest and relevant literature, mostly with a cognitive approach, has attracted attention. In this regard, investigators have tried to she...

In this paper, we propose a logical framework for reasoning about uncertain belief fusion. The framework is a combination of multi-agent epistemic logic and possibilistic logic. We use graded epistemic operators to represent agents’ uncertain beliefs, and the operators are interpreted in accordance with possibilistic semantics. Ordered fusion can resolve the inconsistency caused by direct fusio...

This paper describes the use of syntactical data fusion to computing possibilistic qualitative decisions. More precisely qualitative possibilistic decisions can be viewed as a data fusion problem of two particular possibility distributions (or possibilistic knowledge bases): the first one representing the beliefs of an agent and the second one representing the qualitative utility. The proposed ...

Dempster’s Rule is commonly described as an operator for fusing beliefs. While there are different possible interpretations of belief fusion, there is considerable confusion regarding the exact type of belief fusion that Dempster’s rule performs. Many alternative operators for belief fusion have been proposed, where some are based on the same fundamental principle as Dempster’s rule, and others...

Information fusion is an advanced research area which can assist decision makers in enhancing their decisions. This paper aims at designing a new multi-layer framework that can support the process of performing decisions from the obtained beliefs using information fusion. Since it is not an easy task to cross the gap between computed beliefs of certain hypothesis and decisions, the proposed fra...

In this paper, it is shown that logical approaches to the formalisation of belief fusion suffer from several drawbacks. A first one is due to the fact that the various epistemological roles of involved beliefs are not taken into account. As a result, the set-theoretic union operator is not necessary adequate for fusing beliefs even when such an operator delivers a consistent set of beliefs and ...
