Many-Valued Multiple-Expert modal models
نویسنده
چکیده
In AI and other branches of Computer Science expert models are often studied and used. Here we examine experts which evaluate formulas of modal logic. An expert model consists of a set of experts and a domination relation which dictates how each expert’s opinion is dependent upon the opinions expressed by other experts. Such multiple-expert modal models were introduced and investigated by Fitting in 1991-92. Fitting also introduced Heyting-style semantics for modal logics, called manyvalued modal models, and showed their equivalence to multiple-expert modal models. In this paper, multiple-expert modal models are extended to a system where experts reason in a many-valued fashion: they assign truth-values taken from finite Heyting algebras. These many-valued multiple-expert modal models are shown to be as well embeddable – and thus equivalent – to manyvalued modal models.

Many-Valued Modal Logics II
Suppose there are several experts, with some dominating others (expert A dominates expert B if B says something is true whenever A says it is). Suppose, further, that each of the experts has his or her own view of what is possible — in other words each of the experts has their own Kripke model in mind (subject, of course, to the dominance relation that may hold between experts). How will they a...
متن کاملTableaus for many-valued modal logic
We continue a series of papers on a family of many-valued modal logics, a family whose Kripke semantics involves many-valued accessibility relations. Earlier papers in the series presented a motivation in terms of a multiple-expert semantics. They also proved completeness of sequent calculus formulations for the logics, formulations using a cut rule in an essential way. In this paper a novel cu...
متن کاملAutomata Games for Multiple-model Checking
3-valued models have been advocated as a means of system abstraction such that verifications and refutations of temporal-logic properties transfer from abstract models to the systems they represent. Some application domains, however, require multiple models of a concrete or virtual system. We build the mathematical foundations for 3-valued property verification and refutation applied to sets of...
متن کاملModalities and many-valued: modelling uncertainty measures and similarity-based reasoning and application to Fuzzy description Logics
The talk will began remembering results on papers [22, 15, 16] where the authors model uncertainty measures as fuzzy modalities on a many-valued residuated logics. the basic idea is that uncertainty measures is not a truth degree but could be interpreted as a truth degree of the fuzzy sentence ”the probability of φ”. The main properties being that the language does not allow nested modalities a...
متن کاملNew Representation Theorem for Many-valued Modal Logics
We propose a new definition of Representation theorem for many-valued modal logics, based on a complete latice of algebraic truth values, and define the stronger relationship between algebraic models of a given logic L and relational structures used to define the Kripke possible-world semantics for L. Such a new framework offers clear semantics for the satisfaction algebraic relation, based on ...
