Conceptual Modeling

One of the core research topics of WISE is conceptual modeling. During conceptual modeling, we create models for the system to be developed or for the domain under considerration without consideration implementation aspects. While in the past, the conceptual modeling techniques, such as ORM, UML or ER where very general and could be used for different domains, nowadays domain-specific modeling languages are preferred. These domain-specific modeling languages are tailored to their domain and provide first-class modeling concepts for concepts that are specific for the domain under consideration.


Different research topics and projects of WISE are related to e-learning.

Serious Games

Serious games have great potential as they allow people to acquire knowledge and skills as they play. Serious games include board and card games, as well as digital games. In particular, digital games provides opportunities that traditional methods cannot offer, e.g., simulations that immerse the player into different situations, or incorporating social aspects such as interpersonal skills.

Personalisation of Serious Games

Although, dedicated tools, methods, guidelines and knowledge are essential to realise effective serious games, they still are not a guarantee for success. An important reason is that all people are different: they have different preferences, different abilities, different performance motivations, different personality treats, and so on. What works for one person, may not work for another person. A (serious) game that is engaging and effective for one person may not be engaging and effective for another person.

Context-aware Applications

Context-aware applications are applications that take into account a user's context (e.g. personal preferences, characteristics, agenda) and environment (e.g. people, places and things in the user's vicinity), in order to provide an improved user experience.

Mobile Applications

In this research we concentrate on the development of mobile applications running on mobile devices such as smartphones.

Visualization to Support Transparency and Interaction

We are researching visualization techniques to support transparency of and interaction with a wide variety of applications.


Ontologies are an important research domain in the context of the Semantic Web. In general, WISE is applying the research results from the domain of ontologies in its own research. However also some research on ontology evolution has been performed in the past.

Semantic Web Languages and Technology

Semantic Web technology and languages (like RDF(S) and OWL) is an important area in Web Engineering and for semantic interoperability. WISE is mainly using the results of research done in this domain, but we also contribute to it in the context of different research project.
