UML Style Graphical Notation and Editor for OWL 2

2010

OWL is becoming the most widely used knowledge representation language. It has several textual notations but no standard graphical notation apart from verbose ODM UML. We propose an extension to UML class diagrams (heavyweight extension) that allows a compact OWL visualization. The compactness is achieved through the native power of UML class diagrams extended with optional Manchester encoding for class expressions thus largely eliminating the need for explicit anonymous class visualization. To use UML class diagram notation we had to modify its semantics to support Open World Assumption that is central to OWL. We have implemented the proposed compact visualization for OWL 2 in a UML style …

Sudoku – A Language Description Case Study

2009

A complete language description includes the structure as well as constraints, textual representation, graphical representation, and behaviour (transformation and execution). As a case study in language description, we consider Sudoku as a language, where a Sudoku puzzle is an instance of the language. Thus we are able to apply meta-model-based technologies for the creation of a language description for Sudoku, including correctness checking of a puzzle, and solving strategies. We identify what has to be expressed and how this can be done with the technology available today.

PASSI: Process for Agent Societies Specification and Implementation

2014

PASSI (a Process for Agent Societies Specification and Implementation) is a step-by-step requirement-to-code methodology for designing and developing multiagent societies, integrating design models and concepts from both Object-Oriented software engineering and artificial intelligence approaches using the UML notation. The models and phases of PASSI encompass anthropomorphic representation of system requirements, social viewpoint, solution architecture, code production and reuse, and deployment configuration supporting mobility of agents. PASSI is made up of five models, concerning different design levels, and 12 activities performed to build multiagent systems. In PASSI, the UML notation i…

How to Comprehend Large and Complicated Systems

2002

The basic problem at early analysis stage of the development life cycle is how to quickly comprehend a large and complicated system. One of the ways to comprehend such a system is to build an object model, as it was suggested by the pioneers of object modelling approach such as J.Rumbaugh1 and J.Martin2. In up-to-date terminology it means building a UML class diagram. The authors have got convinced in their everyday practice on extreme efficiency of this type of modelling, though at the same time a significant experience for this job is also required. To make this job easier, a modelling methodology must be developed. The goal of this paper is, on the one hand, to give some methodological r…

Reduction of UML Class Diagrams

2002

One and the same “real world” can be modeled by different UML class diagrams, which in such a case can be considered “intuitively equivalent”. A formalization of this “intuitive equivalence” of class diagrams is proposed. An algorithm is constructed that for two class diagrams determines if they model the same “real world”. This algorithm can be used in CASE tools to compare alternative models of a system, and for diagram “compression” to facilitate understanding of large diagrams.

Pini Language and PiniTree Ontology Editor: Annotation and Verbalisation for Atomised Journalism

2020

We present a new ontology language Pini and the PiniTree ontology editor supporting it. Despite Pini language bearing lot of similarities with RDF, UML class diagrams, Property Graphs and their frontends like Google Knowledge Graph and Protege, it is a more expressive language enabling FrameNet-style natural language annotation for Atomised journalism use case.

Extensible Visualizations of Ontologies in OWLGrEd

2019

OWLGrEd is a visual editor for OWL 2.0 ontologies that combines UML class diagram notation and textual OWL Manchester syntax for expressions. We review the basic OWLGrEd options for ontology presentation customization and consider the framework of OWLGrEd extensions that enables introducing rich use-case specific functionality to the editor. A number of available OWLGrEd extensions offering rich ontology management features to their end-users are described, as well.

Evolution of OO Methods: the unified case

1997

This paper takes an evaluative look into OO methods and especially the evolution of the new snified method from its ancestors, OMT and OODA. The paper ries to classify the components of the earlier ethods and identify the parts that have been taken into the Unified ethod. The research applies the method metrics approach. For the sake of compactness we limit ourselves to the class diagram technique of all methods. We make observations about the number of concepts in each variation and show how the metrics can be used to analyse the changes in the techniques.

Unified Modeling Language

2005

Mature engineering disciplines are generally characterized by accepted methodical standards for describing all relevant artifacts of their subject matter. Such standards not only enable practitioners to collaborate, but they also contribute to the development of the whole discipline. In 1994, Grady Booch, Jim Rumbaugh, and Ivar Jacobson joined together to unify the plethora of existing object-oriented systems engineering approaches at semantic and notation level (Booch, 2002; Fowler, 2004; Rumbaugh, Jacobson, & Booch, 1998). Their effort led to the Unified Modeling Language (UML), a well-known, general-purpose, tool-supported, process-independent, and industry-standardized modeling lang…

Towards a method to generate GUI prototypes from BPMN

2018

Business Process Model and Notation (BPMN) provides organizations with a standard that facilitates further compression of the business process. BPMN focuses on the functional processes, leaving the development of interfaces to one side. Thereby, interface design usually depends on the subjective experience of the analyst. This article aims to propose a new method to generate user interfaces from BPMN models and Class Diagrams. The proposed method is based on the identification of different rules and makes use of stereotypes to extend BPMN notation. The rules have been extracted from seven existing projects on the Bizagi repository. Specifically, the proposal is based on the extraction of ru…
