For more than 20 years, scientists working in the field of Artificial Intelligence have been developing computer programs that could solve problems in a way that would be considered intelligent if done by a human. At present, there are very few expert systems developed for financial applications. The purpose of this project is to investigate the problem domain of loan-processing within the context provided by the United Building Society, a financial institution in New Zealand, and to develop an appropriate prototype expert system to address that problem.
