A first look at an expert computer system

Article Abstract:

Expertech Ltd. of Great Britain is marketing an expert system known as Xi that runs on IBM PCs, as well as on microcomputers manufactured by Wang, Grid Case, Research Nimbus, and DEC. Although the response time on Xi is slow, the system is easy to use (employing a simple English grammar) and seems excellent for recording the expertise in a field such as accounting for simple applications and training purposes. Xi offers existing knowledge bases in personnel management areas and allows users to create new knowledge bases in fields of their choosing. As an expert system, Xi is not 'intelligent', and is only indirectly related to artificial intelligence developments.
