Some first-order probability logics
TL;DR: The logics allow making statements such as P>s, with the intended meaning \the probability of truthfulness of is greater than or equal to s, and the corresponding probability models are described.
Journal ArticleDOI
Some probability logics with new types of probability operators
TL;DR: New types of probability operators of the form QF, whereF is a recursive rational subset of [0; 1], are introduced and it is shown that the new operators are not definable in languages of probability logics that have been used so far.
Journal ArticleDOI
First steps towards probabilistic justification logic
TL;DR: The probabilistic justification logic PJ is introduced, a logic in which the authors can reason about the probability of justification statements, and its syntax and semantics are presented, and a strong completeness theorem is established.
Journal ArticleDOI
Discrete Linear-time Probabilistic Logics: Completeness, Decidability and Complexity
TL;DR: A propositional and a first-order logic for reasoning about discrete linear time and finitely additive probability are introduced and decidability is proved by establishing a periodicity argument for ω-sequences extending the decidable proof of standard propositional temporal logic LTL.
Journal ArticleDOI
A logic with approximate conditional probabilities that can model default reasoning
TL;DR: The paper presents the proof-theoretical approach to a probabilistic logic which allows expressions about (approximate) conditional probabilities and the corresponding strong completeness theorem is proved for a rather simple set of axioms.
