Motivation

  • Conceptual models today widely used in industry and academia
  • Many different types of conceptual modeling languages: see projects
  • n www.openmodels.at
  • Some parts of semantics of conceptual models typically not made

explicit, given in natural language

  • Algorithmic processing of conceptual models interesting for analyses,

simulations, configuration of information systems etc.

  • Solution: Map conceptual models to semantic schemata / ontologies

Challenges:  How to do this for arbitrary modeling languages?  How to provide an open accessible solution?

Components of Modeling Methods

(Karagiannis and Kühn, 2002)

Meta Model = Model of the Abstract Syntax of a Modeling Language

Semantic Aspects in Conceptual Models

  • Basic assumption: Conceptual Models primarily

intended for human understanding and communication

  • Semantics of labels typically only given in natural

language

  • Meta models as a semi-formal specification: Only

syntax and type semantics are formalized

  • Machine processing of models requires

some kind of formal semantics

  • Ontologies as shared semantic schemata

to enable processing

Requirements for Handling Semantic Aspects

  • Approach should be applicable to arbitrary modeling

languages and different types of ontology languages

  • Ontologies should be exchangeable (re-use aspects)
  • Exchange should be based on standards, e.g. OWL,

XML

  • Approach should be easy to use, despite the

necessary formal definitions

  • Support for distributed modeling and semantic

annotation of models in a web-environment

  • Open for further development by the scientific

community

The SeMFIS Approach

Goals:

  • Provide an open platform for handling semantic

aspects in conceptual models

  • Applicable to arbitrary modeling languages
  • Establish a community dealing with these aspects

Includes: – Semantic conceptual model types – Algorithms and support tools – Open accessible web services – Support tools and services http://www.openmodels.at/web/semfis/

SeMFIS Algorithms, Web Services and Support Tools

Currently available algorithms:

  • Exchanging models in XML format
  • Exporting frames ontology models in Protégé frames format
  • Transferring concepts from conceptual models into ontology

models via annotation specifications

  • Obfuscating model information using OWL inheritance

Currently available web services:

  • Access the contents of models via web interfaces (XML / Rest)
  • Generation of various graphical formats of models

Support tools:

  • Protégé OWL Export plugin for SeMFIS incl. upload

to an openmodels.at repository

Implementation of SeMFIS on ADOxx

  • ADOxx meta modeling approach developed since

1995, originally for business process management

  • Part of the commercial ADOxx meta modeling

Platform provided by the University spin-off BOC AG

  • >1000 customers worldwide
  • Available for free for projects within the Open Models

Initiative on www.openmodels.at:

– Open use and access of the platform – Online (RDP) and offline model editors – Currently > 25 academic projects based on ADOxx on Open Models – Variety of free services for developers and users, e.g. wikis, forums, developer tools, etc.

Conclusion and Outlook

  • SeMFIS as a concept and a tool to handle semantic

aspects of conceptual models

  • Realization by using semantic conceptual models

together with algorithms, web services and support tools Future work:

  • Further development of the web

functionalities

  • Provision of evolution and change handling

facilities

  • Additional practical evaluation in research and

industrial projects
