A Logical Account of Relevance
نویسنده
چکیده
The study of relevance has gained considerable attent ion recently in areas as diverse as machine learning and knowledge representation. In this paper, we focus on one particular area, namely relevance in the context of logical theories. We are interested in answering questions like: when is a sentence (or theory) relevant to a set of propositions, or, when is one set of propositions relevant to another given some background theory? The answers are given semantical ly in terms of a logic of belief and syntactically in terms of prime implicates. Furthermore, rather than merely adding yet another set of definitions of relevance to the many that already exist, we also show close connections to two others that were recently proposed, thus point ing to some common ground at least as far as logical relevance is concerned.

This position paper points out the ‘NRT problem’ in specifying and reasoning about information security and assurance: Although it is necessary to deal with normative, relevance, and temporal notions explicitly and soundly in specifying and reasoning about information security and assurance, until now there is no formal logic system can be used as a unified logical basis for the purpose.

متن کاملThe meaning of although: a Relevance Theoretic account
The meaning of concessive connectives like although is notoriously difficult to capture, mainly because these connectives do not contribute to the truth conditions of utterances containing them. In this paper, a Relevance Theoretic account of the meaning of although is given. The connective is analysed as encoding procedural meaning, constraining the inferential side of utterance interpretation...
متن کاملAn Algorithmic Approach to Information and Meaning
I will survey some matters of relevance to a philosophical discussion of information, taking into account developments in algorithmic information theory (AIT). I will propose that meaning is deep in the sense of Bennett’s logical depth, and that algorithmic probability may provide the stability needed for a robust algorithmic definition of meaning, one that takes into consideration the interpre...
متن کاملFour-Valued Knowledge Augmentation for Representing Structured Documents
Structured documents are composed of objects with a content and a logical structure. The e ective retrieval of structured documents requires models that provide for a content-based retrieval of objects that takes into account their logical structure, so that the relevance of an object is not solely based on its content, but also on the logical structure among objects. This paper proposes a form...
متن کاملA Formal Analysis of Relevance
We investigate the notion of relevance as it pertains to ‘commonsense’, subjunctive conditionals. Relevance is taken here as a relation between a property (such as having a broken wing) and a conditional (such as birds typically fly). Specifically, we explore a notion of ‘causative’ relevance, distinct from ‘evidential’ relevance found, for example, in probabilistic approaches. A series of post...
