C ase-based reasoning is most useful in areas lacking a strong theoretical domain model, such as economics, medicine, and law. To be effective in some domains, however, CBR systems must use expert knowledge to determine feature importance when selecting cases that match the current problem. Relying on domain knowledge can be a problem when applying CBR to… (More)
In this paper, we describe our efforts in knowledge building by creating visualizations. Our efforts include problem-based learning. We have identified a problem that the students have in learning OOP. To solve that problem we engage our students in the classroom using existing visualizations created by students of the earlier class, then we have the… (More)
We wish to make frame-based computing easer to deal with by providing a visualization interface. This interface will both show the contents of the knowledge base and show the code execution of a frame-based program. We have implemented FRL, a frame-based language, and extended it with the visualization interface.
In this paper, we describe a model for indexing publications, which span across different loosely federated servers. This situation is found in many universities. The proposed model uses RDF (Resource Description Framework) as a language for describing the metadata for the resources across the digital library network. All the sites and publications in the… (More)
