Modal Logic Foundations of Markup Structures in Annotation Systems

نویسنده

  • Marcus Kracht
چکیده

In this paper I explain how modal logic is used to talk about structured documents and how this relates to markup languages, in particular XML. It will be seen that there is a tight connection between XPath and dynamic logic over ordered trees. This connection allows to get a good insight into the semantics and complexity of XPath.

Impact of Structural Components of Market on the Markup Level Based on Radial Basis Neural Network and Fuzzy Logic

This paper aims to evaluate the impact of several indices of market structure including entry to barrier, economies of scale and concentration degree on 140 active industries using the digit. Accordingly, we apply three methods including cost disadvantages ratio ( ), Herfindahl–Hirschman concentration index ( ) and Comanor and Willson criterion in order to assess the economies of scale and usin...

On Some Aspects of Decidability of Annotated Systems

In this paper, we discuss some results of decidability of annotated systems. The annotated propositional logic P and its S5 type modal extension S5 are shown to be decidable. These results reveal that annotated systems are computationally attractive as the foundations of paraconsistent rea-

Automated Deduction for Deontic Logics: Laying the Foundations of Legal Expert Systems

ABSTRACT: Deontic logic can be used to formalise legal rules. The automation of reasoning in deontic logic can therefore be used as the basis of a legal expert system. In this paper we investigate the automation of deontic logic using tableau calculi for modal logics. The correspondance between the deontic and modal logics is outlined and the tableau for the modal logics used in the prover are ...

Modal Logic over Higher Dimensional Automata

Higher dimensional automata (HDA) are a model of concurrency that can express most of the traditional partial order models like Mazurkiewicz traces, pomsets, event structures, or Petri nets. Modal logics, interpreted over Kripke structures, are the logics for reasoning about sequential behavior and interleaved concurrency. Modal logic is a well behaved subset of first-order logic; many variants...

Suhrawardi's Modal Syllogisms

Suhrawardi’s logic of the Hikmat al-Ishraq is basically modal. So to understand his modal logic one first has to know the non-modal part upon which his modal logic is built. In my previous paper ‘Suhrawardi on Syllogisms’(3) I discussed the former in detail. The present paper is an exposition of his treatment of modal syllogisms. On the basis of some reasonable existential presuppositi...
