Creating and Evaluating Problem Templates for Problem Generation Within the Context of Stroke Cognitive Rehabilitation
Degree GrantorUniversity of Canterbury
Stroke Rehabilitation would be more effective if the patients conducted activities personalised to them, as opposed to a set of generic activities which may be irrelevant. This project has the intention of creating problem templates, which will be able to describe the conditions that must be met for a stroke patient to complete an activity, for a wide range of personalised activities. The project is part of the larger Stroke Rehabilitation System, which the ICTG lab is working on. This customisation of treatment is the motivation for the project. The concept of problem templates is used extensively in this project. Problem templates are “chunks of domain-specific knowledge, compiled mentally by experts, and used to solve commonly occurring problems in a particular domain” . Because of their dynamic nature, it is possible to create very generalised problem templates, which can be applied to create very specific scenarios. This research aims to create many of these templates, with the intent of showing that it is possible to create a varied set of potential problem scenarios, using only a few problem templates for each task. After completing background research, a system for developing these problem templates was developed, and six such problem templates created. The six problem templates were for everyday tasks that stroke patients might perform, such as ‘make hot drink’, ‘make frozen meal’, and ‘make sandwich’. A quick survey rendered a number of specific examples to instantiate the problem templates, such as: ‘make coffee’, ‘make pizza’ and ‘make tuna salad sandwich’. From preliminary examination of these problem scenarios, it would appear that these problem templates can be used to generate problem scenarios, in well-defined situations. For the majority of the specific examples, the resultant dependency graphs of states were the correct solution, or required only minor changes. The Author suggests that further problem templates should be made and that further studies be conducted so as to maximise its effectiveness for the Stroke Rehabilitation Project in the long term.
