Probabilistic Logic under Coherence‚ Model−Theoretic Probabilistic Logic‚ and Default Reasoning in System P

2016

We study probabilistic logic under the viewpoint of the coherence principle of de Finetti. In detail, we explore how probabilistic reasoning under coherence is related to model-theoretic probabilistic reasoning and to default reasoning in System P. In particular, we show that the notions of g-coherence and of g-coherent entailment can be expressed by combining notions in model-theoretic probabilistic logic with concepts from default reasoning. Moreover, we show that probabilistic reasoning under coherence is a generalization of default reasoning in System P. That is, we provide a new probabilistic semantics for System P, which neither uses infinitesimal probabilities nor atomic bound (or bi…

Probabilistic Logic under Coherence, Model-Theoretic Probabilistic Logic, and Default Reasoning

2001

We study probabilistic logic under the viewpoint of the coherence principle of de Finetti. In detail, we explore the relationship between coherence-based and model-theoretic probabilistic logic. Interestingly, we show that the notions of g-coherence and of g-coherent entailment can be expressed by combining notions in model-theoretic probabilistic logic with concepts from default reasoning. Crucially, we even show that probabilistic reasoning under coherence is a probabilistic generalization of default reasoning in system P. That is, we provide a new probabilistic semantics for system P, which is neither based on infinitesimal probabilities nor on atomic-bound (or also big-stepped) probabil…

Eficacia de procesamiento de los entrañamientos y de las implicaturas conversacionales generalizadas: la lógica deductiva y la lógica por defecto

2022

This work aims to study the processing differences that occur between deductive logic and default logic. Since the entailments are based on deductive logic and generalised conversational implicatures (GCI) are built from the default logic, two questionnaires were proposed to collect the processing efficiency expressed as the number of hits per minute. The data collected shows that there is a significant difference in the processing of entailments and ICGs: entailments are processed more efficiently than ICGs and, therefore, it is concluded that the default logic requires greater cognitive effort. Este trabajo tiene como objetivo estudiar las diferencias de procesamiento que se producen al a…
