✦ Synopsis

The large amount of data collected today is quickly overwhelming researchers' abilities to interpret the data and discover interesting patterns. Knowledge discovery and data mining systems contain the potential to automate the interpretation process, but these approaches frequently utilize computationally expensive algorithms. In particular, scientific discovery systems focus on the utilization of richer data representation, sometimes without regard for scalability. This research investigates approaches for scaling a particular knowledge discovery data mining system, Subdue, using parallel and distributed resources. Subdue has been used to discover interesting and repetitive concepts in graph-based databases from a variety of domains, but requires a substantial amount of processing time. Experiments that demonstrate scalability of parallel versions of the Subdue system are performed using CAD circuit databases, satellite images, and artificially-generated databases, and potential achievements and obstacles are discussed.

Central to our approach is the use of knowledge and perceptions about one's adversary to obtain an uncertainty profile indicating which action the a

## Abstract How we understand our surroundings is an age old question. The general understanding is that it is through concepts, categories, and relations that we make sense of our world. This study presents a result of a dissertation that attempted to investigate the nexus between human cognition
