Similarity-Based Logics for Approximate Entailments. Quantitative Logic and Soft Computing

Reasoning under practical circumstances is often inexact. Assumptions might be fulfilled only in an approximate way but conclusions are drawn anyway. Different epistemic aspects may be involved, like uncertainty, preference or similarity. In order to formalise such kind of reasoning we need to go beyond classical propositional logic. In this presentation we will deal with logics for similarity-based reasoning. This kind of reasoning can be cast in the more general framework of reasoning by analogy and has applications, for example, in classification, case-based reasoning, or interpolation.The author acknowledges partial support by the Spanish MINECO/FEDER project RASO (TIN2015-71799-C2-1-P)Peer reviewe
