Verisimilitude and Content
Synthese, 2007Co-Authors: Ken GemesAbstract:Popper’s original definition of verisimilitude in terms of comparisons of truth Content and falsity Content has known counter-examples. More complicated approaches have met with mixed success. This paper uses a new account of Logical Content to develop a definition of verisimilitude that is close to Popper’s original account. It is claimed that Popper’s mistake was to couch his account of truth and falsity Content in terms of true and false consequences. Comparison to a similar approach by Schurz and Wiengartner show certain advantages of this new approach.

Logical Content and empirical significance
1998Co-Authors: Ken GemesAbstract:This paper investigates the possibility of completing a Positivist style account of empirical significance. This is central to the positivists’ core project of demarcating science from metaphysics/the non-cognitively significant/ nonsense. After reviewing various reasons why the quest for a demarcation criterion has long been abandoned, it is argued that none of the traditional objections are compelling. In particular, it is shown that holism, the most widely cited ground for dismissing the possibility of a demarcation criterion, is perfectly compatible with a criterion of empirical significance. What is needed is an account that explains how a claim can be empirically significant within a given theory. It is shown that new research in logic; in particular the account of Content developed in Gemes (1994) and (1996) provides machinery that solves the longstanding technical problems faced by Positivists’ attempts to formulate a holistic account of empirical significance.Article

A New Theory of Content II: Model Theory and Some Alternatives
Journal of Philosophical Logic, 1997Co-Authors: Ken GemesAbstract:This paper develops a semantical model – theoretic account of (Logical) Content complementing the syntactically specified account of Content developed in “A New Theory of Content I”, JPL 23: 596–620, 1994. Proofs of Completeness are given for both propositional and quantificational languages (without identity). Means for handling a quantificational language with identity are also explored. Finally, this new notion of Content is compared, in respect of both Logical properties and philosophical applications, to alternative partitions of the standard consequence class relation proposed by Stelzner, Schurz and Wiengartner.

A new theory of Content I: Basic Content
Journal of Philosophical Logic, 1994Co-Authors: Ken GemesAbstract:Philosophers of science as divergent as the inductivist Carnap and the deductivist Popper share the notion that the (Logical) Content of a proposition is given by its consequence class. I claim that this notion of Content is (a) unintuitive and (b) inappropriate for many of the formal needs of philosophers of science. The basic problem is that given this notion of Content, for any arbitrary p and q , ⌈( p V q )⌉ will count as part of the Content of both p and q . In other words, any arbitrary p and q share some common Content. This notion of Content has disastrous effects on, for instance, Carnap's attempts to explicate the notion of confirmation in terms of probabilistic favorable relevance, and Popper's attempts to define verisimilitude. After briefly reviewing some of the problems of the traditional notion of Content I present an alternative notion of (basic) Content which (a) better fits our intuitions about Content and (b) better serves the formal needs of philosophers of science.

Explanation, unification, and Content
Noûs, 1994Co-Authors: Ken GemesAbstract:The following is an essay on the notion of scientific explanation as unification. In it a new notion of (Logical) Content is used to explicate Michael Friedman's notion of "k-atomicity," and to explicate the notion of the surplus Content of hypothesis h relative to evidence e. From this basis an analysis of unification as theoretical reduction is advanced. A second notion of unification, unification as reconciling prima facie incompatible statements, is introduced again with the aid of this new notion of Content. More generally, it is argued that rather than seek the essence of scientific explanation we should carefully catalog the various distinct explanatory virtues. Finally it is argue that in particular philosophical explanations put a high premium on the quality of unification through showing how to make compatible seemingly irreconcilable claims.

The Logical Content of triangular bases of fuzzy sets in Łukasiewicz infinite-valued logic ☆
Fuzzy Sets and Systems, 2014Co-Authors: Pietro Codara, Ottavio M. D'antona, Vincenzo MarraAbstract:Abstract Continuing to pursue a research direction that we already explored in connection with Godel–Dummett logic and Ruspini partitions, we show here that Łukasiewicz logic is able to express the notion of pseudo-triangular basis of fuzzy sets, a mild weakening of the standard notion of triangular basis. En route to our main result we obtain an elementary, logic-independent characterisation of triangular bases of fuzzy sets.

IDMS - Video Content Management Using Logical Content
Interactive Distributed Multimedia Systems, 2001Co-Authors: Nozomu Takahashi, Yuki Wakita, Shigeki Ouchi, Takayuki KuniedaAbstract:A common video file format is generally used in video Content management system composed of modules for archiving, retrieving, and video streaming on a network. However, the file format may not be suitable for these functions. This paper presents a new video Content management that uses Logical Content. Logical Content makes it possible to manage a system that may use files of differing formats to store the same Content to be used by different modules. Using Logical Content makes it possible to access physical video files regardless of their formats, and to easily manage video Content consisting of multiple physical files. Other modules are able to request the retrieval of a physical file by specifying a Logical Content ID and its range. Consequently, this system can be designed to be both modularized and extended. We also present an experimental video Content management system that verifies the effectiveness of our video Content management system.
