This paper describes the evolution and development of an intelligent information system, i.e., a knowledge base for steel structures being undertaken as part of the Technical Information Center for Steel Structures at Lehigh University's Center of Advanced Technology for Large Structural Systems (ATLSS). The initial development of the Technical…

This paper describes how a language for building information systems that is being developed by the Office for Research at OCLC can be linked to an artificial intelligence environment, Poplog. The demonstration system--ISIS (Intelligent Support for Interface systems)--shows how Poplog could provide some intelligent support for a D interface,…
