A posteriori knowledge: from ambiguous knowledge or undefined information to knowledge
Alvarado Mentado, Matías (1994-11)
Research report
Open AccessIncomplete worlds or ambiguous actions are topics that encourage research in theories about reasoning and action (Brewka and Hertzberg 1993). Driankov's model-based approaches propose to deal with the problem using Belnap's ... -
About the attribute relevance's nature
Núñez Esquer, Gustavo; Cortés García, Claudio Ulises; Belanche Muñoz, Luis Antonio; Alvarado Mentado, Matías (1991-03)
Research report

An approach to belief in strong Kleene logic
Núñez Esquer, Gustavo; Alvarado Mentado, Matías (1995-06)
Research report
Open AccessThree-valued Strong Kleene Logic provides an adequate framework to deal with belief change. In this paper, an undefined truth-value is used to denote opinionless information. Through an informative refinement, such information ... -
Conocimiento en mundos posibles mediante una relación de posibilidad constructiva
Alvarado Mentado, Matías (1993-09)

Open AccessIn the logics of belief, the possible worlds semantic (Kripke 59) is attractive, for its formal elegance and for the intuitive notion of making a discourse, not only of the present world but for any possible world. The ... -
Relative knowledge and belief: SKL preferred model frames
Alvarado Mentado, Matías (1994-02)
Research report
Open AccessThe partial SKL**-logic, defined by P. Doherty in A Three-Valued Approach to Non-Monotonic Reasoning (1990) is based upon the three valued logic of S.C. Kleene. The logic of Doherty provides a flexible framework in defining, ... -
Toward a realistic semantics of possible worlds for logics of belief
Sales Porta, Ton; Alvarado Mentado, Matías (1993-09)
Research report
Open AccessThis work sets out the main ideas concerning a semantics of possible worlds for epistemic logics which do not have the problem of logical omniscience and which can be used to model reasoning with limited resources. Within ...
