A.Avron Multi-valued Semantics: Why and How
According to Suszko’s Thesis, any multi-valued semantics for a logical system can be replaced by an equivalent bivalent one. Moreover: bivalent semantics for families of logics can frequently be developed in a modular way. On the other hand bivalent semantics usually lacks the crucial property of analycity, a property which is guaranteed for the semantics of multi-valued matrices. We show that ...
متن کاملGeospatial Semantics: Why, of What, and How?
Why are notions like semantics and ontologies suddenly getting so much attention, within and outside geospatial information communities? The main reason lies in the componentization of Geographic Information Systems (GIS) into services, which are supposed to interoperate within and across these communities. Consequently, I look at geospatial semantics in the context of semantic interoperability...
متن کاملReflection in Nursing Education: Why and How?
Introduction: Nursing education should develop autonomy, critical thinking, open-mindedness and sensitivity to others. Reflection seems to be an effective strategy for developing such capabilities in nursing. Therefore, this narrative review study was carried out to explore reflection in nursing education. Methods: Using keywords like reflecting, reflection and nursing reflection, FarsiandEngl...
متن کاملOn Multi-valued Semantics for Logic Programs
Abstract: For a general program P, multi-valued interpretations and models are defined, considering a set of truth logic values and an undefined value. The program P may contain constant propositions, which are defined for each truth logic value. Two orderings between the set of all multi-valued interpretations are considered: one is Fitting ordering and the other is standard ordering. The sema...
متن کاملComputing and Comparing Semantics of Programs in Multi-valued Logics
The different semantics that can be assigned to a logic program correspond to different assumptions made concerning the atoms whose logical values cannot be inferred from the rules. Thus, the well founded semantics corresponds to the assumption that every such atom is false, while the Kripke-Kleene semantics corresponds to the assumption that every such atom is unknown. In this paper, we propos...
