Context is important to today's mobile and ubiquitous systems as operational requirements are only valid under certain context conditions. Detecting context and adapting automatically to that context is a key feature of many of these systems. However, when the operational context associated with a particular requirement changes drastically in a way that designers could not have anticipated, many systems are unable to effectively adapt their operating parameters to continue meeting user needs. Automatically detecting and implementing this system context evolution is highly desirable because it allows for increased uncertainty to be built into the system at design time in order to efficiently and effectively cope with these kinds of drastic changes. This thesis is an empirical investigation and discussion towards integrating data mining algorithms into self-adaptive systems to analyze and de fine new context relevant to specific system requirements when current system context parameters are no longer sufficient. / Graduate / 0984 / arook@uvic.ca

This thesis aims to develop a knowledge structuring framework to organize knowledge according to means-ends relationships. Means-ends relationships are particularly relevant in technology and goal-oriented domains such as the geo-engineering domain, where technical problems are identified, and solutions proposed. The proposed goal oriented representation in this thesis does not replace current classification methodologies. In this project, a small corpus of research publications from a technology domain is used to help construct the framework. The main means-ends relationships from the articles are manually extracted and represented in a graphical model showing which problems are approached, by which solutions proposed, and in which publications. Proposed solutions can lead to new problems which are in turn addressed by solutions proposed in other publications. A metamodel is derived to capture the important concepts and relationships relevant for this purpose. The metamodel, and the framework have undergone several iterations before finalization.
