Ontology-based Approach to Competence Profile Management

Competence management has received much attention during recent years because it contributes to achieving organizational goals and solving problems such as improvement of information or competence ...

The Practice of Competence Modelling

A clear understanding of the organizational competences of an enterprise and the underlying individual competences and the competence development needs has become more and more important for many industrial areas as a foundation for competence supply processes and adjustment to changing market conditions. Competence modelling, i.e. the use of enterprise modelling techniques for capturing existing and describing desired organisational and individual competences in enterprises, offers important contributions to this. In the last years, the authors of the paper have performed a number of competence modelling cases, which revealed different characteristics and resulted in lessons learned. This paper presents an examination of different characteristics of competence modelling cases, and recommendations and lessons learned from these cases for the practice of competence modelling.

Information Reuse and Interoperability with Ontology Patterns and Linked Data : First Experiences from the ExpertFinder Project

Semantic web technologies show great promise in usage scenarios that involve information logistics. This paper is an experience report on improving the semantic web ontology underlying an application used in expert finding. We use ontology design patterns to find and correct poor design choices, and align the application ontology to commonly used semantic web ontologies in order to increase the interoperability of the ontology and application. Lessons learned and problems faced are discussed, and possible future developments of the project mapped out.

Ontology-Based Competence Management for Team Configuration

When manufacturers, distributors and dealers need to collaborate, they form production networks because this provides significant advantages in production variety, flexibility and lead time. Production processes in such networks often spawn different specific tasks that are to be solved by the network members. This requires creation of a team able to tackle the identified problem. When dealing with multiple organizations and multiple processes within a complicated production network, trying to find a member that has required competence can be a laborious, time-consuming process. Developing and maintaining competence profiles of all the relevant parties associated with production can significantly reduce the time. The paper proposes an approach to team configuration based on competence profiles. The approach utilizes such technologies as ontology management, context management and profiling. Using ontological representation makes it possible to identify those team members who are best suited for the task by ontology matching.

Modelling of the Ward Round Process in a Healthcare Unit

Information systems (IS) are nowadays extensively used to support all kinds of activities in healthcare organisations. Enterprise modelling can help to make the use of IS in healthcare more effective by providing process and domain models reflecting a particular healthcare unit. This paper proposes a model of the ward round process in a healthcare unit. The proposed model identifies the roles of medical professionals, tasks that can be performed according to the personnel’s competences, and activities that are carried out as part of the tasks to achieve goals of the ward round process. A formal approach has been used to implement the modelling results in the form of an ontology. Such formal ontologies can support improvement and development of IS in healthcare. We learned that modelling workshops are important for development of models that can be formalized in a machine-readable form.

Application of Inference Rules to a Software Requirements Ontology to Generate Software Test Cases

Testing of a software system is resource-consuming activity. One of the promising ways to improve the efficiency of the software testing process is to use ontologies for testing. This paper presents an approach to test case generation based on the use of an ontology and inference rules. The ontology represents requirements from a software requirements specification, and additional knowledge about components of the software system under development. The inference rules describe strategies for deriving test cases from the ontology. The inference rules are constructed based on the examination of the existing test documentation and acquisition of knowledge from experienced software testers. The inference rules are implemented in Prolog and applied to the ontology that is translated from OWL functional-style syntax to Prolog syntax. The first experiments with the implementation showed that it was possible to generate test cases with the same level of detail as the existing, manually produced, test cases.

On the Role of Competence Models for Business and IT Alignment in Network Organizations

Customer-motivated changes in network organizations lead to alignment of business and IT-infrastructure. This paper investigates the use of competence models in network organizations for more efficient alignment of IT-infrastructure to changed business demands. The paper shows that a competence model is pertinent in a process of aligning an IT-infrastructure to changed business demands. Then, a way is presented of extracting alignment needs from competence information in enterprise models. Finally, our approach for competence profile management is extended with alignment operations. These operations together with other operations on competence profiles form a lifecycle model for competence profile management. Such operationalization allows for support of aligning network organizations to changing business demands.

Modeling Network-Based Defence: Success and Failure of an Enterprise Modeling Endeavour

Research projects have an inherent risk of failure, and learning how to cope with the risk is an important task for everyone involved. In order to do so it is necessary to share the knowledge of the experiences done during and after the project. This paper investigates a recently completed enterprise modeling research project and contributes with lessons learned and recommendations for future enterprise modeling projects.
