If a new piece of information contradicts our previously held beliefs, we have to revise our beliefs. This problem of belief revision arises in a number of areas in Computer Science and Artiicial Intelligence, e.g., in updating logical database, in hypothetical reasoning, and in machine learning. Most of the research in this area is innuenced by work in philosophical logic, in particular by GG ...

Most logic-based approaches to knowledge and belief change in artificial intelligence assume that when a new piece of information comes up, it should be merely added to the current beliefs or knowledge when this does not lead to inconsistency. This paper addresses situations where this assumption does not hold. The focus is on the construction of Boolean standard-logic knowledge and belief base...

4. Philosophical studies of knowledge. These are often not so much concerned with finding out facts as with establishing norms or standards. So philosophers try to find criteria for deciding whether certain beliefs are rational, or whether inferences from evidence to conclusions are valid. A closely related topic is the study of the systems of concepts required for formulating beliefs of differ...

Issues of formalisirig and interpreting epistemic uncertainty have always played a prominent role in Artificial Intelligence. The Dempster-Shafer (DS) theory of partial beliefs is one of the most-well known formalisms to address the partial knowledge. Similarly to the DS theory, which is a généralisation of the classical probability theory, fuzzy logie provides an alternative reasoning apparatu...

The situation calculus of (McCarthy and Hayes 1969) 1 has mainly been used to reason about states of the physical world, taking into account the locations and physical properties of objects and admitting such events as moving them. Analogously we can consider a mental situation calculus (MSC) in which the situations include beliefs, goals, intentions and other mental qualit ies, and the events ...

The aim of the study was to examine some overlooked individual difference (demography, ideology, ability) correlates attitudes being vaccinated with Covid-19 vaccine. Six hundred and sixteen adults were asked about receiving COVID-19 relationship between demographic (age, sex, education), ideology (political religious beliefs), intelligence (cognitive vaccination (acceptance, hesitancy, rejecti...
