We have also moved from looking at the shape of data to the meaning of that data. Whether it is downloaded from the Internet or an organisation's local data capture, there is little point in storing information if we can't make sense of it.
These two related problem areas are the basis for our research. Data mining looks at mechanisms for finding nuggets of knowledge in a mass of data while conceptual modelling attempts to organise data in a manner that means that we retain its meaning and its context. Our program of research thus has two interacting parts:
- The Data Mining part focuses on investigates the development and application of advanced algorithmic, architectural and visualisation techniques to the problems of deriving, or assisting in the derivation of, knowledge from potentially large volumes of complex data. These three areas use allied techniques and overlapping methodologies although they differ in the quantities of data, the initial information content of that data and the way in which the data is presented to the user.
- The Conceptual Modelling part aims to develop conceptual models for complex systems and to explore how these models can be used to build data-oriented solutions to difficult problems. In particular, while current conceptual modelling techniques have proved adequate for many problems, they cannot adequately model many advanced semantic relationships characteristic of complex systems.
These two areas come together when we investigate the accommodation of ontologies in data mining and in other ways.
