SD2: a sound and complete diagrammatic reasoning system

J. Howse, F. Molina, J. Taylor
Proceeding 2000 IEEE International Symposium on Visual Languages  
SD2 is a system of Venn-type diagrams that can be used to reason diagrammatically about sets, their cardinalities and their relationships.  ...  We discuss the soundness of the system and develop a proof strategy for completeness simpler than that adopted by Shin.  ...  and proved the soundness and completeness of the system.  ...

On the Completeness and Expressiveness of Spider Diagram Systems [chapter]

John Howse, Fernando Molina, John Taylor
2000 Lecture Notes in Computer Science  
A set of reasoning rules for a spider diagram system is shown to be sound and complete.  ...  Spider diagram systems provide a visual language that extends the popular and intuitive Venn diagrams and Euler circles.  ...  Our longer term aim is to prove similar results for constraint diagrams, and to provide the necessary mathematical underpinning for the development of software tools to aid the diagrammatic reasoning process  ...

A Survey of Reasoning Systems Based on Euler Diagrams

Gem Stapleton
2005 Electronical Notes in Theoretical Computer Science  
Recently much research has been conducted to develop formal, diagrammatic reasoning systems based on Euler diagrams.  ...  Most of these systems extend Euler diagrams by adding further syntax to increase expressiveness. In this paper we survey such systems and draw comparisons between them.  ...  Whilst the Venn-II system is not particularly expressive, Shin does show that diagrammatic notations can be formalized and given sound and complete reasoning rules.  ...

Spider Diagrams

John Howse, Gem Stapleton, John Taylor
2005 LMS Journal of Computation and Mathematics  
A number of simple diagrammatic transformation rules are given, and the resulting reasoning system is shown to be sound and complete.  ...  This paper develops a purely diagrammatic reasoning system of "spider diagrams" that builds on Euler, Venn and Peirce diagrams.  ...  In [37] , Sun-Joo Shin gives a cogent summary of this long-standing 'prejudice' against diagrammatic reasoning, before developing two (sound and complete) reasoning systems of Venn diagrams.  ...

A Diagrammatic Inference System with Euler Circles

Koji Mineshima, Mitsuhiro Okada, Ryo Takemura
2012 Journal of Logic, Language and Information  
We prove the soundness and completeness theorems with respect to a formal set-theoretical semantics. We also investigate structure of diagrammatic proofs and prove a normalization theorem.  ...  We formalize the unification rule, which plays a central role in Euler diagrammatic reasoning, in a style of natural deduction.  ...  semantics and inference systems are given, and basic logical properties such as soundness, completeness, and decidability are shown.  ...

Diagrammatic Reasoning System with Euler Circles: Theory and Experiment Design [chapter]

Koji Mineshima, Mitsuhiro Okada, Yuri Sato, Ryo Takemura
Lecture Notes in Computer Science  
Accordingly, in order to fill this gap, we formalize an Euler diagrammatic inference system and prove the soundness and completeness theorems with respect to a formal set-theoretical semantics.  ...  We further consider, from a proof-theoretical viewpoint, the structure of diagrammatic proofs and manners of their construction. 1 Throughout this paper, we mean by a circle a simple closed curve.  ...  Furthermore, in Based on Venn's and Peirce's work, Sun-Joo Shin [1994] formalized a diagrammatic reasoning system called the Venn-II system.  ...

Managing Assurance Cases in Model Based Software Systems

Sahar Kokaly
2017 2017 IEEE/ACM 39th International Conference on Software Engineering Companion (ICSE-C)  
However, as systems undergo evolution for a variety of reasons, including fixing bugs, adding functionality or improving system quality, maintaining assurance cases multiplies the effort.  ...  For companies, compliance is a complex and costly goal to achieve and is often accomplished by producing socalled assurance cases, which demonstrate that the system indeed satisfies the property imposed  ...  The goal would be to develop sound ways to model this interplay and reason about it as systems evolve.  ...

Modular session types for objects

Simon Gay, Nils Gesbert, António Ravara, Vasco Vasconcelos, Davide Sangiorgi
2015 Logical Methods in Computer Science  
We define syntax, operational se-mantics, a sound type system, and a sound and complete type checking algorithm for a small distributed class-based object-oriented language with structural subtyping.  ...  The result is an elegant unification of communication channels and their session types, distributed object-oriented programming, and a form of typestate supporting non-uniform objects, i.e. objects that  ...  Ravara was partially supported the Portuguese Fundação para a Ciência e a Tecnologia FCT (SFRH/BSAB/757/2007), and by the UK EPSRC (EP/F037368/1).  ...

The findings related to knowledge, skills and attributes matched fairly closely with the published literature on the topic, but were of a much more specific and very basic nature.  ...  The findings of the study showed that there exists a specific set of knowledge, skills and attributes which are regarded and agreed by all of the stakeholder groups as being vital to mental health nurses  ...  The recordings were transferred to the computer, and upon playing them back through the computer's sound system, 2 out of 3 of them were very Page -62 clear.  ...
