Creating Semantic Representations of Diagrams [chapter]

Mark Minas
2000 Lecture Notes in Computer Science  
Diagrams that serve as a visual input facility for programming environments have to be translated into some kind of semantic description.  ...  This paper describes such a method which is based on a specification of the translation process.  ...  The method that has been described on the previous pages is based on representation of diagrams by hypergraphs, which are a generalization of graphs.  ...

Exact graph-based analysis of scientific articles on clinical trials [article]

Ilya Levin
2017 bioRxiv   pre-print
This article describes Amorpha, a software package based on new concept of exact graph-based linguistic analysis.  ...  In addition to text representation, analytical results are presented as graph images showing essential concepts of a text.  ...  In other words, each node of hypergraph has the information about his environment just after building of hypergraph.  ...

Metrics-Based Spreadsheet Visualization: Support for Focused Maintenance

Karin Hodnigg, Roland T. Mittermeir
2008 arXiv   pre-print
We thus propose different visualization and representation methods that may ease spreadsheet comprehension but should not be applied with all kind of spreadsheet programs.  ...  Since spreadsheet programs are as diverse as the purpose they are serving and as inhomogeneous as their programmers, to find an appropriate representation or visualization technique for every spreadsheet  ...  Based on these considerations, different maintenance issues are addressed. They are contrasted with various visualization approaches proposed so far.  ...

Concepts and realization of a diagram editor generator based on hypergraph transformation

Mark Minas
2002 Science of Computer Programming  
Created editors use hypergraphs as an internal diagram model and hypergraph parsers for syntactic analysis whereas syntax-directed editing is realized by programmed hypergraph transformation of these internal  ...  hypergraphs.  ...  Manual programming is necessary for the visual representation of diagram components on the screen and for processing speciÿc data structures of the problem domain, e.g., for semantic processing when using  ...

Visualizing The Intermediate Representation of Just-in-Time Compilers [article]

HeuiChan Lim, Stephen Kobourov
2021 arXiv   pre-print
We describe a new approach for simplifying the large and complex intermediate representation, generated by a JIT compiler and visualize it with a metro map metaphor to aid developers in debugging.  ...  Just-in-Time (JIT) compilers are used by many modern programming systems in order to improve performance.  ...  Reducing the IR Hypergraph We first convert the simplified graph G = (V, E) into a hypergraph H = (V, S), by extracting hyperedges based on the optimization phases.  ...

Syntax Definition with Graphs

Mark Minas
2006 Electronical Notes in Theoretical Computer Science  
The paper presents in a tutorial like way the DiaGen approach of defining visual language syntax with hypergraphs and hypergraph grammars.  ...  Syntax definition of visual languages is required for a precise definition of a visual language; it is a requirement for the automatic creation of tools that process diagrams of the language.  ...  Editor specific program code which has been created by the DiaGen designer's program generator from the language specification is responsible for the visual representation of these language specific components  ...
