1a. Research Interests

- Logic-based knowledge representation,
- Conceptual modelling & ontology languages (Description Logics (& OWL), Object-Role Modeling, etc.)
- Relations in (bio-)ontologies, such as parthood and other part-whole relations
- Ontology Engineering
- Granularity
- Biological data characteristics

1b. Research Activities

The main thread across my research activities is ontology, ontologies, logic, and conceptual data modelling. They are divided into three paragraphs for presentation convenience, and a final paragraph on participation in funded projects.

Ontology engineering and logic-based (bio-)ontologies
     In this strand of investigation, I consider automated reasoning for formal (FOL, DL and OWL-ized) bio-ontologies, formal properties of relations (e.g., parthood), ontology engineering, foundational ontologies, modularity. Earlier work also involved Ontology-Based Data Access and bio-ontologies, including particpation in funded projects (among others, ARISTOTELES, TONES, Net2).

Formal and ontology-driven conceptual data modeling
     This strand of research combines the logic and modelling from ontologies with conceptual data modelling (in, e.g., ER, ORM). This includes logic-based reconstructions (mainly in Description Logics) of the diagram languages, model linking and integration, and various extensions, such as formal temporal conceptual data modelling. Some related funded projects were the Ontology-driven unification of conceptual data modelling languages and an earlier projects on "Technologies for Conceptual Modelling and Intelligent Query Formulation".

Controlled Natural Languages
     This strand of research extends from the ontology engineering, by focussing first on controlled (a particualr fragment of) natural languages and natural language generation for knowledge-to-text, and for Bantu languages in particular. I am PI of two funded projects in this area, being a A Grammar engine for Nguni natural language interfaces (GeNi) and a UCT Science Faculty grant on foundations thereof, and an earlier project looked at terminology harvesting in COMMUTERM.

Granularity
     The development of a formal theory of granularity (TOG), my PhD thesis topic, covers subtopics such as mereology, indistinguishability, types of granularity, abstraction and expansion, rough sets, and formal ontology.

Information on earlier education
This has been moved to a separte page, here, and contains summaries of, and links to, the PhD, MSc, MA, and BSc(hons) theses and papers resulting from them.

In case you are wondering about the difference in given name that appears in publications, C. Maria, and my 'regular' name, Marijke: this is due to some odd naming conventions in the country I grew up (the Netherlands); Marijke is derived from Maria. I use my official name for scientific publications, and (used to use) the other one for other activities.
