Remarks on the cognitive base of pragmatic principles
The present paper aims at the exemplification of the applicability of plausibility analysis to linguistics. Starting from the criticism of Robinson (1997), the paper argues for two assumptions. Firstly, as opposed to a theory of distributed systems, it is a theory of plausible reasoning that is capable of capturing basic methodological problems of theory formation in pragmatics (such as circularity, category error, the arbitrariness of interpretations of data and the objectification of the theorist's cultural and linguistic knowledge as principles of language behaviour). Secondly, the cognitive base of pragmatic principles is inferential and plausibilistic, rather than non-inferential and probabilistic
A Labelling Framework for Probabilistic Argumentation
The combination of argumentation and probability paves the way to new
accounts of qualitative and quantitative uncertainty, thereby offering new
theoretical and applicative opportunities. Due to a variety of interests,
probabilistic argumentation is approached in the literature with different
frameworks, pertaining to structured and abstract argumentation, and with
respect to diverse types of uncertainty, in particular the uncertainty on the
credibility of the premises, the uncertainty about which arguments to consider,
and the uncertainty on the acceptance status of arguments or statements.
Towards a general framework for probabilistic argumentation, we investigate a
labelling-oriented framework encompassing a basic setting for rule-based
argumentation and its (semi-) abstract account, along with diverse types of
uncertainty. Our framework provides a systematic treatment of various kinds of
uncertainty and of their relationships and allows us to back or question
assertions from the literature
Probabilistic Reasoning with Abstract Argumentation Frameworks
Abstract argumentation offers an appealing way of representing and evaluating arguments
and counterarguments. This approach can be enhanced by considering probability
assignments on arguments, allowing for a quantitative treatment of formal argumentation.
In this paper, we regard the assignment as denoting the degree of belief that an agent
has in an argument being acceptable. While there are various interpretations of this, an
example is how it could be applied to a deductive argument. Here, the degree of belief that
an agent has in an argument being acceptable is a combination of the degree to which it
believes the premises, the claim, and the derivation of the claim from the premises. We
consider constraints on these probability assignments, inspired by crisp notions from classical
abstract argumentation frameworks and discuss the issue of probabilistic reasoning
with abstract argumentation frameworks. Moreover, we consider the scenario when assessments
on the probabilities of a subset of the arguments are given and the probabilities
of the remaining arguments have to be derived, taking both the topology of the argumentation
framework and principles of probabilistic reasoning into account. We generalise
this scenario by also considering inconsistent assessments, i.e., assessments that contradict
the topology of the argumentation framework. Building on approaches to inconsistency
measurement, we present a general framework to measure the amount of conflict of these
assessments and provide a method for inconsistency-tolerant reasoning
A Model for an Intelligent Support Decision System in Aquaculture
The paper purpose an intelligent software system agents–based to support decision in aquculture and the approach of fish diagnosis with informatics methods, techniques and solutions. A major purpose is to develop new methods and techniques for quick fish diagnosis, treatment and prophyilaxis at infectious and parasite-based known disorders, that may occur at fishes raised in high density in intensive raising systems. But, the goal of this paper is to presents a model of an intelligent agents-based diagnosis method will be developed for a support decision system.support decision system, diagnosis, multi-agent system, fish diseases
